Win7 process lock-ups triggering RAID repairs. Solutions?

I have Win7 Premium, with four hard drives: one hard drive specifically for the OS (written to the outside of the platters and the rest of the drive unaccessible so that the drive head never moves and I get seek times faster than a Raptor), two identical 1 tb SATA drives in a mirroring RAID, and a 1 tb external drive.

My problem is that Win7 keeps locking up processes on a fairly regular basis (ie/ once every couple of weeks or so) so that they can’t be shut down, even from the task manager. I’ll be playing a game, the game will crash, and Win7 will refuse to terminate the process. Googling this shows others have the same problem. I can’t shut down properly because Win7 isn’t able to terminate all the processes properly, forcing me to do a manual reset.

When I reboot, about half the time it fuxx0rz my BIOS so that it forgets boot load order and I have to set it all again. Then when I do manage to reboot Win7, it triggers my RAID and I spend the next six hours twiddling my thumbs while it verifies and repairs data, during which time my computer is a very expensive paperweight.

Anyone have any suggestions or solutions? Don’t tell me to “switch to *n?x,” because I’m hostage to Windoze unless and until WINE achieves gold level emulation for the games and other software I use (after which I will have a snowball fight with His Satanic Majesty).
