"My car doesn't work."
Armed with such detail all I can write is your car needs repair.
Details such as what happens, what error messages (or messages) you see are clues to what may fix each area. Also nice to know is the OS is up to date.
Look up XP SR.INF on google.com which notes articles such as http://www.annoyances.org/exec/forum/winxp/t1061090103 in which a common SR repair is noted. But while safe to do I can't know if that will help.
Any BETA software should be revealed and what pest control you are using.
My compatability wizard and system restore are not working ! Do I have to reinstall my windows xp home edition sp2 OS, or is there another way to repair them? I have a Dell 4500 series/640MB RAM and just recentley upgraded my video card with a GeForce 5200 AGP card.Please help if you can...Thanks
