Microsoft XP suddenly craping out.

Seriously, XP has been working find for the past 4 years and all of a sudden it's getting slow and restarting for no reason. I have no viruses or anything like that. Do you think it's a marketing ploy to buy Vista?

u should probably reinstall or repair windows once a year, cause windows is very unstable. I installed windows, and it screwed its own registery in one day, go figure. However, I don't recomend anything else like linux, cause I think its more 31337 to mod windows than linuxs, cause at least there's a challenge when modding windows.
