Black Screen on Startup/Yellow light

[sirheinouslot]

This has been happening ever since my computer shut down when I applied a bad overclock on AMD Overdrive (but I've never used that overclock again)

When I start up my computer it beeps (been happening for two months now) it starts up, then it quickly boots into the Profile log in screen.. then the screen turns black and the monitor light goes yellow. Capslock or any key on the keyboard doesn't work either. When I push the power button in and start the computer up again, it goes through all the proper booting procedures instead of going straight to profile log in, which is why I can post this thread.
Hardware:
GTX 960 2GB
FX 4300 3.8ghz
8gb RAM 1600mhz
MSI 760GM-P23(FX)

Have you checked the BIOS to see if the OC has been undone there?

 

[sirheinouslot]

Sorry for late reply. The overclock has been undone there. I noticed that when I go to bed, if I forget to switch off the plug for my computer and WiFi (after shutting down pc), the next morning the computer refuses to start up. Meaning I have to switch off the plug and switch it on again to get the computer to work.

You mean the PSU switch?

 

[sirheinouslot]

No, I mean't the switch to the computer. The plug that connects the computer and wifi to electricity.

If this is a desktop pc then it is the PSU switch indeed. And this seems to be static to me, does it seat in a carpeted room?

 

[sirheinouslot]

Yes, its in a carpeted room, but the desktop itself is not on the carpet.

Unplug the PC off the power and press the power button of the case a few times to discharge the static. If that doesn't work, perhaps clearing the CMOS settings will do.

You mean the power button which lights up, the front one? And if so I have done that already to no avail.
