A couple weeks ago, I started up my desktop, it configured the updates it had just installed, and then it bluescreened before everything finished starting up (no explicit error message there, which was weird. Only advice it gave was to check that I had enough disk space, or something like that). Since then, whenever I turn it on, it POSTs, shows the mobo splash screen, then gets stuck on "loading operating system" and has to be turned off. I can get into the BIOS and the boot options menu, but I can't get into the advanced startup options to try safe mode or anything like that. I've tried booting from a USB copy of windows 7, but that doesn't seem to work either.

My initial guess was that the update's installation got corrupted by the blue screen and borked the OS, but it should still boot from USB in that case. I have been having some random bluescreen crashes for a few months now with the error "Driver Power State Failure," as well as one with "IRQL not less or equal," so that's made me suspect some hardware's dying, but I'm not entirely sure. I also got "Modification of system code or a critical data structure was detected" once, which prompted a virus scan and a memory diagnostic, but both came up clean. Thoughts on what the issue might be?
