Amnesia Blue Screens My PC

[Your Computer]

I wouldn't say the RAM is defective, or else i'd expect you to be crashing in just about everything, not just Amnesia. Nevertheless, i wouldn't entirely disregard hardware failure. My guess is Amnesia is trying to access a system file that got corrupted somehow. You could probably fix it with a restore point some time before the date this all occurred. If the blue screen starts to "migrate" into other programs, then i'd start considering hardware failure.
