Hello, I come to you with a problem. I wasn't sure which forum to go to with this, but I think that this is the most likely location. Last night, my desktop PC blacked its screens as though it had gone into sleep mode. After trying various inputs, all to no avail, I decided to hard reset. Upon turning back on, the screens remained black and computer would not boot at all. Also, the front power/reset buttons did nothing at all after starting it back up. The power button would start up the computer, but pressing and/or holding it did nothing at all, same for the reset button. I unplugged it and opened the case, to see if there were any loose connections. I saw none, so I once again started the computer back up. There were no beeps, no readout on the small LED display in the corner of the mobo. The lights for the power, reset, and clr CMOS buttons (the buttons on the mobo itself) all had lights on, however. Everything else also seemed to power on; my fans, CPU, and video card were all on. But there was no screen, and no sign of the mobo booting. I have had similar problems before, so I went through and unplugged the mobo connectors and plugged them back in. After all that, my PC booted back up as though nothing at all had gone awry. So I went back about my business, as I was doing before.
Then it happened again, under the same circumstances (playing an online game.) I figured that case vibration had shaken things loose again, which is nothing new. So I did all those steps again. This time, however, nothing. The 3 buttons on the mobo light up, but no LED, no booting, no sounds or beeps. Nothing. I began searching the internet with this problem, and found quite a lot of similar problems. I attempted many of the fixes listed on this forum, as well as many others. Clearing CMOS, shorting the 24-pin connector, taking out the battery for a few hours, discharging the caps. I even left everything unplugged overnight, but still the same problem arises. Everything powers on, but the computer does not boot.
Now, I am still unclear as to the true problem. I understand the possibility of a faulty PSU is present, and I am still hoping that it is indeed the culprit. However, it just feels like a mobo issue. I don't have any sort of itemized list of settings or components, as all that information is on my desktop, and I am unable to access any of it. Like I said before, I searched for hours last night, looking for anyone with this exact issue, but found nobody. Most of the similar issues I found were solved by rather simple means, all of which I tried. I still don't understand why I was able to get it working again the first time this problem came up by unplugging then re-plugging in all the power connectors to the mobo, yet now I cannot. I know for certain that I didn't cross or short anything myself.
Please, if anyone has any advice or possible solutions, let me know.
