For the past few weeks I've been having a problem with STOP errors that I just can't figure out. I'm running the latest and greatest of all the drivers for my system and the problem seems to be getting worse instead of better. I've got an Asus A8N-E with AMD64 3000+, ATI X700 PCIe video card abd a SATA harddrive. I'm using the sound and network on the motherboard. Following the advice in this forum I ran memtest86+ and in three separate sessions with anywhere from 8 to 14 passes I got no errors. I don't *think* it's RAM, but of course I don't know what it is so anything's possible. The reason I think the problem could be related to APM is that it only seems to have the problem if I'm not physically using the machine. It may be downloading, encoding movies, etc. as long as I'm using it, no problem. If I leave the room for an hour I almost always come back to find it's rebooted. I had some info showing up in the event log but after some research I've been able to correct most of what I was seeing, but I still have this issue and now I get nothing of interest in the event log (at least that my untrained eyes can find). I've attached 5 minidumps. Any thoughts?
