I've been running XP for over a year now and I haven't had too many problems with it other than what is to be expected in that amount of time. In the last few days I've noticed a big slowdown in performance on my machine. I checked the processes tab in task manager to check what was taking up most of the mem usage. I found that instead of the usual 3,000 to 6,000k that explorer usually takes it was at 35,000. I killed the process and started it again and then watched a movie. When I was done with the movie everything was just barely moving it was so slow and explorer was not taking up 150,000k of mem usage. I haven't really changed anything hardware or software recently that would do something like this. Does anybody know what I can do to fix it? Do you just reccomend a repair installation? Any help is appreciated, thanks. Oh, I've got an AMD Athlon 1600+ and 256mb ddr ram. I need more ram but I don't think that is the problem here.
