Hey, I read through the thread on how to debug minidumps, and have included the logs. I can include the original dumps if you prefer. A little history: I bought and built 5 identical computers in June, all new parts. Two of them are blue screening a lot, the others are fine. The computers are lightly used for business, so mainly MS Office and Quickbooks and not overclocked. They are connected to a switch and a windows 2000 server for a shared drive. They are basically: AMD Athlon 64 X2 3600+ Dual Core Processor Socket AM2 Brisbane 1.9GHZ 2X512KB 65NM 65W Retail Box ASUS M2A-VM mATX AM2 AMD 690G DDR2 PCI-E16 PCI-E1 2PCI Video VGA DVI Sound Motherboard Patriot Signature Line 2GB 2X1GB PC2-6400 DDR2-800 CL5 240PIN Memory Dual Channel DIMM Kit Seagate Barracuda 80GB 7200.9 8MB SATA Hard Drive Antec Sonata III Black ATX 16IN Mid Tower Quiet Case 3X5.25 2X3.5 4X3.5IN 500W Air Duct 120MM Fan I doubt they are overheating, very cool in here and those cases breath well. The power supply should be fine, 500W antec. I had video driver problems with all of them at first, but I guess that was a known issue with this mobo and seems to be resolved in more recent driver versions. I've updated the bios. I've ran memtest and made it through a full pass with no errors, I haven't had a chance to run longer yet. I'm hoping someone can help me out. I'm thinking it's onboard video problems still, or RAM. Network issues couldn't cause this could it? I know our network doesn't run great, but I can't see how it would cause this and only on 2 computers. The two computers I'll reference by the users Rita and Corrine. Rita's seems to be random, any program can cause it, and about once a week but getting more frequent. Almost always a pink square somewhere on the bluescreen. Corrine's usually happens sometime during the night when no one is on, her's is the only one left on 24/7 to do backups. I noticed a pink square this morning on the bluescreen, but I don't know if it has been there ongoing. I will post Rita's logs in this message, corrine's in the next.
