First off I'd like to just say Hi, and any and all help would be greatly appreciated. I've been pulling chunks of hair out for 3 days now trying to fix this problem. I re-installed XP 2 days ago after having some bad luck with Warcraft all of a sudden. My system was locking up if I enabled sound, yet if I turned sound off, no lock up. Now that I've reinstalled, my system locks up randomly, even while just resting at my desktop. Walk to the store, come back 30 mins later, PC is completely frozen, reset required. Last night for the first time, my PC didn't lock up but rather just rebooted on me, and after I loaded again it said Windows has recoevered from a serious error, and I got this error: C:\DOCUME~1\UserName\LOCALS~1\Temp\WER4779.dir00\Mini010007-01.dmp C:\DOCUME~1\UserName\LOCALS~1\Temp\WER4779.dir00\sysdata.xml I reinstalled XP again tonight, got all my drivers set up and installed (chipset NForce4 Ultra, Nvidia display, Creative), and was pretty optimistic that it was ok until it completely froze up on me during the installation of my first Windows Update batch, the one with some Internet 6.1 fixes, the one right before they give you SP2. I got another random reboot after that, and I actually found this error in my Event Viewer/System: Save Dump The computer has rebooted from a bugcheck. The bugcheck was: 0x10000050 (0xfe805303, 0x00000000, 0xfe805303, 0x00000000). A dump was saved in: C:\WINDOWS\Minidump011007-01.dmp I'm at a total loss. I currently run the Abit AN8 Fatal1ty Socket 939 board, with an AMD Athlon 64 X2 Dual Core 3800+. This board did not support X2 CPUs until its BIOS v15, and I upgraded the BIOS to the current v20 2 days ago. My system specs are: Mobo - Abit AN8 Fatal1ty RAID CPU - AMD Athlon 64 X2 Dual Core Processor 3800+ Soundcard - SB Audigy 2 Videocard - NVIDIA GeForce 7800 GT RAM - 2 Gig Corsair VS1GB400C3 HDD - WDC WD740GD-00FLC0 (Western Digital 74gig 10K Raptor) PSU - Turbolink ATX-CW 500P4 12v (500 WATT MAX) Optical drives - PIONEER DVD-RW DVR-110D & TEAC CD-W524E It's not the best system in the world but it's not the worst. I've had these components for roughly one year, and just recently something has gone bad. I'm leaning towards my mobo being the culprit, and am more than happy to upgrade to a new one like the Asus An8 32x if need be. Anyone have an idea on what my problem is? Thanks a ton again for any and all suggestions.
