What RAM do you have along with what Graphics card you use. As coolraj003 said, put ur specs on otherwise we are in the dark to your problem!

assuming that you have an older pc with <512mb ram, you should add more ram, and if you have any cpu less than a p4, upgrade your cpu.

If you have no intent to spend a few $$ on ram and many $$ on a cpu, unfortanately, reinstalling windows and starting from scratch is the best way to go, though you could debug every trifle program and hardware device (while you could be starting fresh with a clean install) until you find the problem (if you find it). Same thing happened to me, upgraded to 2gb ram (for $28.99) and reinstalled windows (with a full data backup of files, music, photos, etc.) and my slow aluminum paperweight shot up like a rocket!!
