i just bought a custom pc and it was working fine for a few weeks. suddenly i started get the blue screen of death every once and a while, i could reboot and continue using my computer. Now for some reason my computer is dead, i cannot run windows. Right as it is about to load windows,(after the screen where the symbol "-" blinks a few times, it freezes at a black screen. I cannot boot from windows disk and i also ran memtest with no problems detected.
