I have a Gateway computer and run Windows 98 SE. Periodically, whether I'm on the net or not, the computer will freeze. If I'm downloading a web page, working in a CAD program, playing solitaire, or whatever, the mouse pointer will freeze, or whatever I am downloading will stop. After a few seconds everything resumes as normal. I recently took the tower in to a computer repair service and had them check it out(it had been freezing up completely). They checked for viruses, adware, etc., reported nothing, but suggested I add more memory. I told them to go ahead with the memory. This problem also causes the sound to stutter and videos to actup, making it very frustrating to listen to music while working. Can you help me? Thanks in advance.
