I'm running Windows XP Professional on a Dell Latitude C800. I got it as a refurb, so I'm not sure how old it is (it was a gift, and I thought it rude to ask). It's a Pentium 3, 128 ram, 40 GB hard drive. Lately I've been having a lot of problems with it. Whenever I install SP2 it completely shuts down and Windows can never successfully open. Usually I do a system restore to get rid of it, but the last time I couldn't even open Windows in safe mode. I had to completely reinstall Windows, since nobody around me knew what to do.
Now the computer is running very oddly. The hard drive makes no noise most of the time, which is unusual, and the computer freezes or pauses a lot more often than it used to. I don't know what to do! Does anyone have any advice?
