She also checked all the cables and everything. I assume the mobo is working right because the LED light is turning on (hopefully that's a good sign), but the case came with its own power supply with a bunch of M/F connectors that I had plugged in, but I have done everything, I think several times, to no avail.It may not be important, but on the side panel of this case, there is a side fan that should connect to a M/F connector (I think) on the PSU. If it still doesn't work, just remove any PCI devices except for the videocard (unless it's an on-board videocard, in which case you just remove all PCI devices). I had a similar issue a long while back that was the results of Video sync issues with the monitor syncing with my video card. I tried the fan test, the PS is fine. [they replaced it] The Power Good line should change state about 100 to 500 milliseconds after the supply mains start. Poor Dell onsite tech, horrible job!

Yes, she did try that too, just forgot to mention that in the first post. If everything is connected properly and still nothing comes up on your computer’s screen, then the second-best way to identify it is an internal hardware problem or an external. Just trying to help. She shut it down, and tried to reboot. The only change is the pin number. a brief tutorial about the components of a personal computer and where the motherboard fits into the scheme You can tr… First download the software, let it detect all of your PC's RGB devices, and then select the motherboard icon at the top. They decided to just wait until I can come and take a look at it. You have tried a known good replacement power supply with no luck. This tells you which pins are the "start" button. I don't know if that is something that should be considered or not (there are two green cables that come out of the front of the case that I've been hooking it up to. I am having issues with my motherboard LEDs not turning off when the board system is Shut Down. Too late in the day for me.If only the power supply fan comes on . I've seen an issue similar to this a few years ago, where because the CMOS battery was flat the computer would only spin up the fans. Here's my specs: AMD Ryzen 7 1700; ASUS Prime X370-Pro; Gainward GTX 1080 GLH; 2x8GB Corsair Vengeance LPX DDR4-3000; Corsair RM1000x PSU + BitFenix Alchemy 2.0 cables. The lights would come on, the fans would spin (case fan, cpu fan, power supply fan, video card fan). My computer was working fine then it wouldn't start up at all by pressing the power button - i.e. I replaced the motherboard but the problem still presists. I have not "seen it all, done it all"...but I have worked in electronics all my life....and on some occasions, things get tricky. Strip it to a bare minimum and see if it will boot. I've seen dead mainbards from Dell (laptops and desktops) more than i should have seen..honestly i can say that those were old models (circa 2008 till 2010), because newer models don't suffer from completely engineering stupidity like this board from a GX620: (in case you are wondering what's wrong, let me tell you that all those capacitors near the CPU are in the most hottest area of the board and not dumb enough the case of this wonderfully crap desktop has only one fan... that pushes air into the CPU and directly to the HDD, without any way to vent it. I want to be sure it's a mobo issue before I replace it, but I'm thrown off by the LED indicators. PC build won't power on at all, no lights, no fans. If it gets a start signal from the main board ,( and the power supply fan starts to run) .. and then won't run your case fans...It would seem that something is wrong inside the power supply.However, if the main board has a componet which is failed in a short circuit state, it is possible that the power supply is shutting down as designed. Does the processor heat sink fan come on, and the case fans...do they also come on ? The outlet works just fine. Feel like I'm gonna have to, though.But yeah, it is still not starting up (LED light is still turning on, though. As others have indicated, likely a graphics card issue, especially if it's an nvidia chip as indicated in the wiki. I need this up and running ASAP, so any help anyone could give would be helpful (I'm praying it's not the case's PSU, because I cannot wait too much longer, and I don't make an awful lot of money, and PSU's are looking expensive at Newegg and Tiger). All that the mobo power control circuit does is tie the green wire to a logic low when you hit the power on switch.I had a 450 Antec where all the power turned on but the sytem would not boot. Black screen. The first 20 wires are unchanged physically. However, the monitor says “VGA NO INPUT” and the DRAM light on my motherboard is on. After a quick restart it wont boot anymore. No sound, just the fans spinning up, then the light starts blinking and the fans spin back down. So far nothing.. Detach any DVD / CD drive and HDD. I know is a very simple step and dunno if you already tried (I didn't read it in the thread). Another thing to check, especially with Dells, is for bad capacitors. Also tried a couple of other things... pulling out the CMOS battery for a few minutes to reset it, and trying to start it without any RAM just to see if the mobo would give me the "Hey, gimme some RAM stupid!" Now onto my problem... the other night I was sitting at my computer, happily playing EA Sports MVP Baseball 2005. Have you tried replacing the motherboard (CMOS) battery? Sorry. Whenever I press the power button the fans all spin, four lights turn on and stay lit on the motherboard but the PC doesn't actually start. Unplug every external device, except for the keyboard, monitor and power. I was troubled, because the spec sheet said the PS was backward compatable. There is no beep however, and no video. Nothing which could defeat or overheat the system. It was displaying the debugger light for the CPU. The fans actually go crazy, spinning at full force. Don't know what kind of cheap, leaky crap they use, but that's a pretty common problem in them. The fans actually go crazy, spinning at full force. After that, the experience I had is similar to what was earlier discussed... the mobo's LED light beside the 24-pin main power connector is illuminated, the LED indicators for the LAN connection are illuminated, and - most frustrating of all - when I press the power button, the front-of-the-case power LED comes on, but nothing else happens. Motherboard on but not booting I have plugged in everything and then turned on my computer according to the instructions for first time boot up. (I'm building a PVR). But I don't think it is the problem here as your FANS still spin and you are getting BIOS bleeps. I even took it out of the case to rule out shorting, removed the CPU 4pin connector leaving only the CPU, CPU fan, and 24pin connector. If yes let us know. I've got the POST test card now and some of the lights stay lit on it but it doesn't seem to show any codes just four lines in the led display where the codes are meant to be. I know that the PSU and CPU fan are good - I … I have a gigabyte aorus pro wifi board with amd ryzen 3700x. There was one more thing I didn't say, but when I first attempted this, I had plugged the PWR cord in the wrong place, but when I went to plug it in the right place the night before, the fans went for about a second and then stopped, as if it WAS going to work, but then just stopped, and hasn't done anything since regardless of what I've done (don't remember what the specifics were when this happened. This just gets better and better! (when you press the start button).....and you have your case fans plugged into the 12volt rail(wiring harness) on the power supply....then the power supply is getting a start logic signal from the main board..so the power supply is the likly problem, not the mainboard. Figuring a flaky power supply, I bought and installed another one. System would be fine, next power up randomly, it would not POST or do anything else, but the fans would go into a high speed mode making the tower sound like a wind tunnel. I would power it on but only fans would work, on-board LAN worked too (i think, because its LEDs are flashing), but no power for the keyboard and mouse. I will post again , when I try to install the new one. The monitor light remains orange and doesn't go green. Still wondering if that is a optimistic sign that at least the mobo has a chance of not beingg fried. ; C RGB PC Lighting Sync: click the big chain icon in the upper right corner, you may sync RGB LED light effect to all product. (No lights). The pictures of the case in the link I gave should provide good indication of the type of connectors it is, one female, one male, and right now, I have them in such a way that if you take out those green cables, the other cables connect to themseves and not the PSU). I have lots of expierence in building up computers, but I had the same problem as you. Look at every capacitor on the motherboard and check that they haven't burst. Here is a list of what i tried : HP M8300F I disconnected everything, cleaned … A friend told me that it might be CPU that prevents it from booting, primarily because of insufficient cooling, so I went on buying a new CPU fan (Deep Cool Gamma Archer), and then installed it. Maybe simply a bad supply. This is somewhat similar to what happened to one of my desktops before, it has an Intel i3 processor and only uses the integrated graphics module. The capacitors don't have to be blown all to bits either. I even purchased new RAM & a power supply. 1 to 10 are still the same and what was 11 t0 20 are now 13 to 22. Was running C4D with Redshift IPR not activated, Substance Painter and Chrome with a bunch of tabs. The computer was dusted out, though it was already pretty clean to begin with. If it turns out not to be a graphics card problem, or memory. RGB lights on the motherboard are working but wont turn on. The Green wire that is either pin 14 [in 20 pin] or pin 16 [for 24 pin] is the pin that the logic ciruit puts a logic low on to turn on the main rails.Take a brand new supply out of the box plug it into AC power with the rear switch on and simply jumper the green wire to any of the black wires on the same cable and the supply will turn on as evidenced by its fan running. Try changing resolutions on your monitor and maybe demagnitize. Then I put the CPU back in, put the cable for power for the motherboard into the PSU, then put the CPU power cable into the PSU, and plugged that into MB, and then I turned it on. a standard four pin Molex connector. No bios. Have read a number of comments about Antec supplies arriving DOA.There was one minor change in some supplies. I've seen as well damaged boards that shared a similar situation, but those boards had a all common factor: faulty capacitors. Fans don't even attempt to spin, no LED Lights, no Beeps, its like the PC is completely unplugged. Fans are running. A Click the product icon on top to change RGB LED light for each product. Screen does not power up but fan and hard drive spinning. Is the PC using a on-board graphics card or a PCIe card? Just completed a new PC build last night. http://www.newegg.com/product/product.asp?item=N82E16819103023), http://www.tigerdirect.com/applications/SearchTools/item-details.asp?Sku=ULT31796, Car Parts, Gadgets, & How-to's - Roadshow. Japan's asteroid return mission arrives on Earth, YouTube will ask users to rethink before posting potentially offensive comments, Cyberpunk 2077's exact launch and pre-load times detailed, PC won't boot - No video, no beep, but fans spin, https://en.wikipedia.org/wiki/Dell_XPS#XPS_630, http://www.digitus.info/en/products/accessories/misc-accessories/pc-atx-power-supply-tester-da-70601/. If you are really needing your computer, you should take it to a repair shop, where they can test each componet, and you only pay for the one you need.Sorry if I confused you the first time. Alright, I took everything out, all of the cables, the cpu, the motherboard, and fans. THe processor WAS fine 2 hours ago, it was in my desktop. For ASRock Motherboards. I had plugged everything in several times, trying different orientations and what not, making sure everything is in right, but nothing will turn on except the mobo LED light on the board. Do you hear fans starting to work inside the PC? My thought is the power supply is screwing up, but they don't have an extra one to test it with. We jokingly call it the self clean mode as it pushes dust out fast. ; B Select any color, effect, light speed or the brightness you prefer, and click “Apply” button to save your preference. I also installed the Thermaltake BigWater SE liquid cooling system. Some case fans turned on, the cooler pump was on, and the mobo seemed on. http://www.thenakedpc.com/dan/Bulging_Capacitors/close-up.jpg, Thanks, I'll have her take a look at the capacitors :) And thanks for the articles, I'll pass it along, So far it's a no go. I recently bought a Asus A8V-VM Socket 939 Motherboard (http://www.tigerdirect.com/applications/searchtools/item-detailsInactive.asp?Sku=A455-2136) (about a month or so ago) and then even more recently got me a Aspire X-Infinity case (http://www.newegg.com/product/product.asp?item=N82E16811144076)to put all of this in (the AMD Athlon 64 processor (http://www.newegg.com/product/product.asp?item=N82E16819103023), two memory sticks, a Sound Blaster sound card, two Maxor HDDs, two DVD disc drives (one just a DVD Rom, the other a DVD Burner)). I assumed it was the PSU, went out got a new one, put it in, same result. It turned out that the mainboard was the root of the problem with a bad controller on it. Thank you all for the help :). So far nothing, but from the sounds of it, can be a very small brown speck, which makes it difficult to find.. Just a tiny, tiny brownish spot on the tops of them and they're toast. The desktop still does not boot. If it does, from there on just start plugging devices back in. Now the fan starts, the red led on the mobo lights and I hear a couple of faint clicks as if something wants, or has tried, to start (one immediately with power on and a second a couple of seconds later. The model is https://en.wikipedia.org/wiki/Dell_XPS#XPS_630 if that helps any. if you have no beeps or any response but just lights and fans running, then there are oly 3 things that can go wrong here, 1, psu gone bad (how old is the PSU) 2, CPU over heated, heat sink clogged or overclocking or just the weather and placement of that computer does effect your PC. I'm using a heat pipe that clips on, so that will be kind of hard to get off (I feel like I'm going to break the clips or worse whenever I go to remove it). There is no onboard video....I had been hoping there would be, but there isn't, and no extra video cards laying around at the moment...I'll see if he has something to test the power supply with, a multimeter or something. It sounds like a power surge may have taken the mainboard out. It's still giving me the little red light and continuously resetting. No I assume the motherboard is fine. You told her to move all RAM modules, but didn't state if you let her boot with just one module. They always had a Minus 5 volt wire and a Minus 12 volt wire. Then connect that to the first controller port by clicking on the light bulb icon with the A1 next to it. Nothing else, no drives no video card, no keyboard or mouse.Between each step turn power off COMPLETLEY, no LEDon.Hit the power button, does the power supply come up as noted by the supply's fan and CPU's HSF coming on and STAYS ON. I started working, got everything installed, double and triple checked my connections, hit the power button.... and no post. It turned out to be a bad batch of mainboards that missed the QC of things. Not that this would be the same for your computer, but at my job, we had a bad run of HP's that would do the same thing with their fans. I've tried the manual switch, the cardboard and pulling everything out. I'm hoping it's not a motherboard problem...Power supplies are cheaper than motherboards lol. If ALL fans come on, and you hear clicking (probably the hard drive)..then I would suspect the processer is dead. This will add the fan into the top left-hand corner, next, we click on the light bulb icon of the added fan. The light effect is still adjustable as previous step. She also unplugged everything on the outside. She isn't comfortable with unplugging everything on the inside. So until I can take a look at the computer personally, and do what others have suggested, she is stuck using a pc that isn't quite as good lol Could be a couple months before I get to take a look at it..Unless she can bring it to me sometime lol. Any fans spinning? I reseated the RAM and the connectors and still nothing. See if that does anything. Under the Light Effect column, click off. The pins that have voltage fom the Power Supply on them are always female, so that you won't accidently short the hot leads to ground.The fan will then run at consnt maximum speed from the 12 volts from the supply. Press and hold the power button for around 15 seconds. Not sure if that will help you. Reconnect the cables and see what happens. All trademarks mentioned are the property of their respective owners. 3, Bios could be corrupted or possibly blown. yeah....), They will be picking up a multimeter to check it out (Always nice to have one around anyways lol, http://www.esaitech.com/images/detailed/3/GGG/img54820.jpg, That is some bad planning on Dells part then lol Thanks for that info, I'll have her look at the capacitors near the CPU extra carefully :). The last thing you want to reconnect is your HDD, you don't want it to boot to Windows at this point. As long as that contact is maintained the supply will stay on. However when the system goes into shutdown the headers turn off but the motherboard LEDs go into rainbow cycle mode. After several hours and numerous test, I finally put the old power supply back in, and everything worked fine. I took it to a computer repair shop & they said I needed a new motherboard. They aren't the most tech savy, and are afraid of breaking something, so I'll test the other suggestions at a later date. I am not saying it is the case with your board, but if the fans are doing the full speed action upon cold boot with no post, this is a pretty good indicator of something deeper than a few loose cables. I sent the powersupply back to Antec, for replacement, with a detailed explanation to them....waiting to get it back. What I do not notice in your post, OP, is the RGB Fusion software. The motherboard lights up but neither fan spins and nothing happens. Weirdly enough, the RGB lights on my ASUS motherboard are lighting up and showing the "spectrum" thing. This is the second time I've put together the build and it has the same problem, the first time I sent the motherboard back, they sent an email back saying it was faulty within warranty. Please help! Now the first thing you’ll need to make sure about your monitor is, that it’s ‘Powered ON’ and the video cable is connected properly.Most of the times just because of some loose cable, a lot of people having this black blank display related problem. I'm in the same boat... Chaintech 7NIF2, Aopen H400 200W PS. Help my laptop's screen isnt showing any display but lights are on and fan is spinning: Laptop not loading, fan spins, hard drive spins,stops and repeats without sending signal to the screen: Laptop black screen fan spin at full speed non-stop: Laptop turns on. location when coming from one end of the connector. We are grateful for the participation and advice you have provided to one another over the years. CMOS did nothing, and no beeps from the mobo when no RAM was installed. She has tried some of the suggestions here, but doesn't want to break things further. Hey there. I tried to power it … The issue: Turn it on and everything seems to get power, fans run up, LED’s on the motherboard, graphics card and CPU cooler light up, monitor and keyboard both get power. After digging around on Antec web site, I found a link to a PDF file that gave industry standards for ATX power supplies, including the pin out for all connectors to the main board. The 20 pin was numbered from 1 to 10 along one side and 11 to 20 along the other side. Hope not). Any suggestions on what and how to troubleshoot? If the fans still dont spin it could be just a faulty fan controller in the front I/O - you can get a replacement for that by contacting rosewill, or alternatively switching it out for another case or switching out the fans for other fans and see if that fixes the issue. If the mobo power supply turn on logic is working, when you hit the power switch its logic turns the remaining power supply rails on [5 volt main, 3.3 volt, 12 volt] Side comment, do you have the 4 pin 12 v connector plugged in [this is not necessary for the supply to turn on but is necessary for the CPU to work]? http://www.theinquirer.net/inquirer/news/1137385/nvidia-bad-bump-misery-deepens. Similar to darkprwjd, my desktop is doing the same thing, the only difference is how we got there. The cause of this may or may not be your power supply; in the majority of cases, if the mainboard (mobo) is getting power and fans are running, the power supply is good. I'd go for the minimalistic route. Neither are used any more so some mfrs don't bother putting a Minus 12 volt rail in to save money.My Antecs came ith a little manual that gave all the wiring info. Does anyone have any ideas that I can pass along, before I go in search of a power supply? By And I can't help her with that, since she is visiting with her dad out of town. I tried replacing RAMs from other units as well, but that did not solve the problem. But … Pins 11, 12, 23, and 24 are the four pins added at the far end. The lights would come on, the fans would spin (case fan, cpu fan, power supply fan, video card fan). I also had her remove the BOIS battery for 1 minute, and replace it. Pull the MB CR2032 battery for about 10 minutes to reset CMOS. Nothing connected power or signal but power supply to mobo, CPU/HSF plugged in, One stick of memory. GIGABYTE GA-78LMT-S2PT rev 4.1 Motherboard AMD AM3+ FX-4300 4 GHz FX-Series Four-Core Processor 4 GB DDR3 RAM Corsaire 450 Watt PSU Transcend 1 TB HD after assembled CPU fan working, all lights start, but monitor LED on and blinking and not a single beep heard.
