Hi! My computer has recently been rebooting for no reason. I have: -Formated my HDD and reinnstaled windows -Updated my system drivers and graphic drivers -Gone through your "Before posting your minidumps, please read this." But I can't seem to figure out what it is. My system is: -CPU: AMD Athlon 64, 2000 MHz (10 x 200) 3200+ -Graphic: GeForce 6600 GT (128 Mb) -HDD: Maxtor 7B250S0 (233 Gb) -Motherboard: DFI LanParty nF4 Series -RAM: 2x Corsair CMX512-4400C25 After my computer restarts my windows error report tells me its something wrong with my Video graphic drivers. But I have updated them. The error logs in the event viewer tells me this: Date: 10.12.2006 Source: System error Time: 22:10:22 Category: (102) Type: Error Event ID: 1003 User: N/A Computer: My computer Description: Error code 0000004e, parameter1 00000099, parameter2 0003476f, parameter3 00000007, parameter4 00000000. In the bluescreen they give me this error msg: Stop 0x00000000a Minidumps attached. Thanks so much! Greetings from Norway!
