System: AN8 SLI, AMD 64 3800, 2 GB Patriot, Geforce 6800 GT 256, 2 PATA\nDVD drives, 40GB PATA HD (boot), 200 GB PATA HD, 200GB SATA HD. Win XP\nSP2 32-bit.\n\nA few weeks ago I got my first BSOD in years. It happended once and\nthen did not happen again for a few days. Now, the computer starts up\nand just after logging in it goes to one of several BS. The ones that I\nremember off of the top of my head are 50, BE, and 8E.\n\nAfter much trial and error, it seem that the onboard NIC is the\nculpret. When disabled in BIOS, the system boots and is stable. Just as\na note, I have swapped out the RAM and had the same problem, so I think\nthat it is safe to rule that out. Also passes memtest (though it did\nhang once during memtest)\n\nThe system has the current NForce drivers and BIOS. Windows is fully\nup to date. Passes virus and adware scans.\n\nI have read on the NVIDIA forum that there might be conflict between\nthe SATA controller and the NIC but I have not had a chance to fool\naround with combinations to see if I can find an SATA port that does\nnot give this problem. In principle, I do not think that I should have\nto. If I try that and it does work, the board is going to be returned\nor sold.\n\nAny thoughts or similar experiences?
