However, I am having the following problem... I can boot to login just fine (XP Pro, multiple accounts), and get into each account as expected. But I am only able to launch a few applications; others just fail to start. More clearly, I can start any arbitrary apps, but only 3-4 of them. Anything after that begins to load, but crashes immediately out. There are no other symptoms, it doesn't matter what apps I am loading, and the CPU is reporting normal loads. The page file seems a little smaller than usual, but I don't see how that would cause this kind of problem.
Worse, I'm not even sure how to search for this kind of issue. I've run virus and malware scanners ad nauseum, but nothing seems to come up.
Any ideas? How can I even begin to search for this sort of thing?
Thanks for any insight!
