At first startup each day, when my system is cold, system reboots several times showing the following errors: “A problem has been detected and Windows has been shut down to prevent damage to your computer. STOP: 0X0000005, 0XBF9BB233, 0XF7A78970, 0xvtdisp.dfl-Address BF9BB233 base at Bf9B7000, DateStamp 3f14f615 Beginning dump of physical memory Physical memory dump complete’ System then stabilizes and runs perfectly “for days” and gives no more problems until next initial startup when system is again cool. Anyone has any suggestions? Thanks.

I would guess the power supply. Antec makes a power supply tester for $15, or use a voltmeter to test it. MCSE, MCSA Messaging, baby!
