This morning from 09:18 to 10:50 it seems that my PC has crashed for 6 times (6 dump files). This is totally new, windows was idle only running a P2P program in the background during the first one. Here's the error log: The computer has rebooted from a bugcheck. The bugcheck was: 0x100000d1 (0x2e353532, 0x00000002, 0x00000008, 0x2e353532). All the same. What could cause this, RAM? I built my PC like 2 months ago and my system had passed stress tests like Memtest, Prime95 without a problem. I also found this Warning at 05:52 in the morning: The time service has not been able to synchronize the system time for 49152 seconds because none of the time providers has been able to provide a usable time stamp. The system clock is unsynchronized. * I'm running Windows XP Pro.
