Any suggestions on fixing a slow desktop? Windows 7 about 5 years old. Ran CCleaner, Spyware removers, Antivirus and anything else I can think of. Sometimes when you try to start a program you just get a spinning circle and it takes a while to open if it ever does open. A shutdown and restart helps slightly but only for a short period. Seeing it did not come with a Windows disc it looks like only way to reinstall is to buy one, repair disc does not work that I made. Tried a restore but it only has a recent point to go back to. Any suggestions?
