While gaming on my computer (any 3D game, from Minecraft (no mods) to World of Warcraft, sometimes my graphics driver crashes and recovers, and I can still continue playing whatever I was playing, although with a severely reduced framerate. Other times, I'm finding my computer emitting a loud, shrill continuous beep (followed by a complete lockup, where there is no sound, no input, nothing), which doesn't match any beep codes. No sound, no artifacts, it just goes kaput, and I need to reboot it. What could be causing this? I have updated all of my drivers to their latest versions (minus the BIOS), made sure my power options were set to High Performance in Windows, dusted the system out, and reseated my graphics card and RAM, with no luck so far.
