Before re-installing your operating system, scan your computer using Ewido Anti-Spyware. It works very well and it's free for 30 days. You can always uninstall it afterwards. If the problem persists, back up your important information and do an operating system re-install.

If it is not a RAM problem, reinstall Windows XP. Chances are when you uninstalled some softwares, you deleted more files than you need.
Reinstall the os
Your computer may possably be low on ram
