I don't know what's happening but the 500 mhz computers being running badly since google earth was installed and ie crashed at 98% and then google was ran. On my last post on the computers unknown performance improvements the computer has finally started to run less hot again and has started to run at less usage but the computers somehow running even better. I think their could be a problem with the computer as it shouldn't be running better for no reason and it might be the eye of the problem and get a lot worse. It used to run at 100% usage after trying to run gogle earth after ie had crashed at 98%.
