Had a random BSOD earlier for "memory management" and now can't get it to even boot past the windows splash screen. Immediately get a BSOD for "system service exception" and it restarts.

I've tried removing/swapping RAM sticks and the video card and that didn't fix it. Cannot get it to boot in safe mode either. Anything I can try real quick tonight before I take it in tomorrow to the local shop?
