On the system I've sold (eck.cjb.net), I'm having a little trouble with XP. First, I got XP installed and everything was good. Then I installed the VIA 4.49 Hyperions and XP started crashing. I figured it was the drivers. I coulnd't try to uninstall the drivers or XP would crash. It seems like it would crash every 10 minutes or so, or if you tried to do something in windows -- for example, reading files on a CD-ROM, or viewing system information. I never did turn off the "automatically restart" under "system failure" to see what it was saying. I figured it was just the VIA drivers so I was going to do a format. It formatted fine, but then when XP went to copy files I had trouble. It got to 29% or so and said "the file copied does not match the source file". I though it was a fluke so I restarted and tried to copy again. Same thing happens, around 29 or 30%, but with a different file. This time I did "skip file" and it might copy a file or two, but then it would have the same thing. I just kept skipping files and finally it blue-screened. It said "IRQL_NOT_LESS_OR_EQUAL". I've seen that before, but can't remember how I fixed it. I tried re-copying the files a few more times, but I would get the IRQL error, but every now and then I got some "PAGEFILE_NOT something". I can't remember exactly what it said, but something to do with the pagefile... and it had the word "not" in there somewhere. BAH, I'm stuck. I can't figure out what the deal is. My XP CD doesn't have any scratches, so that shouldn't be the problem. Any ideas would be helpful.
