i built a new computer for gaming last week and what get on my nerves is that i get crashes and reboots during gameplay now and then. And wherenver after the reboot, i get this error report that some kind of unknown driver is causing the trouble, and microsoft has no solution... after this, i have my video card (nvidia 7900 gtx) replaced with a new one. But the crashes and reboots continue. This is really pissing me off. I spent loads of money on this rig and now it runs worse than my old comp.
