BSOD - a process or thread crucial to system operation...

Hi,

I've been having this persistent issue for the past month or so now.

Every time I turn on my computer, it's like having it on a timer before it BSODs. And every time, its the same message -- A process or thread crucial to system operation has unexpectedly exited or been terminated. Then the computer restarts on its own, only to get stuck on the boot screen telling me that Windows had failed to start. The only way to fix this is to hard reset the computer.

Any suggestions would be greatly appreciated.
