I'm having problems with my Dell notebook running Win XP Home (Original; came with the laptop). Not sure if it's a security problem; have run spybot S&D and turns up DSO exploit which keeps on coming back. I'm not sure if that's the reason for the problem.
Anyway, IE won't start properly, and I have problems with Windows Explorer after a minute or two of startup. My ICQ and MSN won't start properly either.
Mozilla works fine (duh).
I tried reinstalling WinXP (not a clean install) but to no avail. Any help appreciated.
