This PC is acting really wierd. It seems to work fine for a few weeks or so, then starts cyclic booting, BSOD, or just stops/freezes with no errors. Event viewer seems clean. Memtest and HD test both pass repeatedly. Any help? Thanks. I think it may be the mobo or CPU. Mini031307-01.dmp is the most recent and has lots of info. Zipped minidumps attached.
