My system reboots about once a day randomly. It's a brand new system that I've installed a fresh copy of Windows XP. The only thing that I've done to it thus far is load the drivers from the motherboard site and patch it with XP SP2 and critical updates. Reviewing the event viewer, I get one informational System event (Eventid 1001) when the computer reboots: The computer has rebooted from a bugcheck. The bugcheck was: 0x100000d1 (0x4b574008, 0x00000002, 0x00000000, 0x8003b020). A dump was saved in: C:\WINDOWS\Minidump\Mini022506-02.dmp. Then when I login as a user, I get a System Error popup that creates a second event viewer System event (Eventid 1003): Error code 100000d1, parameter1 4b574008, parameter2 00000002, parameter3 00000000, parameter4 8003b020. Here's how my environment is setup: Motherboard: Giga-Byte GA-8NSLI (REV1.1) CPU: Intel Pentium D 930 Memory: 2 GBs Corsair Video: Radeon X600 Please help!
