Hi,
About 2 days ago my computer crashed. Nothing special happened, I was browsing the internet and all of a sudden it turned off. I tried to restart it, but when I pressed the power button nothing happened - no fans spinning or anything. There was still power inside of the case, the light on my graphics card was on and all the USB ports worked (both the ones directly on the motherboard and the ones on the front of the case). I tried jumping the power pins, then the computer would turn on roughly every 10 power cycles. I decided to leave it for a while until I had a chance to properly look at it.
Fast forward to today: I tried to turn it on and it worked! However now the PC does not boot past BIOS. The BIOS hangs for about a minute and a half, and I get single short beep from the POST speaker I installed on the header. Then after the 4th beep the screen goes blank. A cursor briefly flashes in the top left corner but this does not last for more than a second. After that the computer stays powered on, but the screen is blank. My monitor does not flash up with a "No Input" warning. I tried replacing the battery on the motherboard with one from a friends computer (so I know that battery works) and I still get the same result.
Anyone got any ideas?
*UPDATE*
For some reason my computer boots again now. It is still taking over a minute to get past the inital BIOS splash screen, and it is completely unresponsive during this time (which is a shame, because I really need to access a VirtualMachine and it's started complaining about VT-x being disabled). And sometimes I need to press the power button several times to get it to actually turn on
Here's my full system specs:
Motherboard: GA-Z77X-D3H
CPU: i5-3550
RAM: 8GB Corsair Vengance
GPU: Gigabyte 980Ti WaterForce
PSU: Seasonic Snow Silent 750W
