Hi guys, been having problems with system stability recently. System basically restarts randomly. Have tried to pin down the cause but can't so am requesting help. Have tried the steps in the sticky above on refreshing the page file. defragging etc. Problem still hasn't gone away. All rams have cleared 7 cycles of memtest at 2.65 volts and 2.6 volts without problems, though everything has been reset to stock already. My system specs are as follows : AMD 64X2 4200+ MSI K8N Neo 4 Platinum 2 x 512mb Kingston CH5 PC3200 DDR 2 x 512mb Mushkin Black Line BH5 DDR Inno 6600GT 128mb Creative Audugy ZS Platinum BenQ 1640 Gigabyte CD-RW Hitachi/IBM 80GB SATA II Western Digital 240GB SATA HD Verudium Vortex 430W Am fairly sure its not a power issue and the core temp never exceeds 49 degrees even at full load. Its about 44/45 idle. +12V is at 17 amps so am guessing that thats not the problem either. Am guessing it might be the soundcard though... Anyone able to help? Last 5 minidumps attached. Would be most grateful for any assistance and thanks in advance.
