So my brothers PC has this issue where it would boot into a black screen once in a while(usually the first time when you power it on, and then the second time too). You can clearly hear the computer still running, but the monitor just turns off(blue LED -> Orange LED happens with the power botton).
There is no indication to what is wrong, as in no sounds, LEDs on the motherboard blinking any messages.
I do see the BIOS screen everytime. I have Windows 8 x64 installed with the latest updates and what not(same goes for NVIDIA drivers).
