If your computer's recent enough to be running XP you may just need to clean it up a bit. Putting exact error messages into Google (put them in quotes!) very often brings up fixes you can make. You might also want to check that you're not storing things you don't need (Start > Settingss > Control Panel >Add/Remove Programs and get rid of what you're not using), and run a disk cleanup and defrag (they'll be in Start > Programs >Accessories > System Tools). While a lot of Win98 computers are still running fine, they are getting on now, and are probably best replaced when they start to die. WinME was just a PITA.
