My roomate's computer has been having a problem where the screen goes black (no signal) there is a grinding/distorted noise coming over the headphones, and the PC is frozen, needing to be turned off by holding the power button and restarting. Not sure if it's related, but sometimes the display driver crashes as indicated by a pop up bubble from the taskbar that says the display driver has crashed and must be recovered. The problem seems to occur randomly, and can happen whether playing a game like World of Warcraft, or even watching a video on youtube for example.
I'm really at my wits end as to what could still be causing this issue. I don't remember the full specs of the original deskop config where this problem started happening, but I have upgraded the PC, replacing the motherboard, memory, CPU, and graphics card, I've even tried swapping out the power supply with the one from my PC which I know works fine and is far beyond the wattage required by her PC (750 watt), and changing hard drives. Hardware of the PC listed below.
