Hello Everyone. Any computer wizz's able to help me at all? I've got a acer aspire laptop and the other night I was downloading a few things had a video on and a few other bits a pieces, so it was working pretty hard. Then all of a sudden the computer crashed, completly stopped, nothing worked at all even the mouse. So I held the power button and restarted it. Ever since then it goes REALLY slow and explorer.exe keeps crashing. I also have those gauges on the sidebar and the RAM gauge never goes lower than 56% even when I'm not doing anything?? I've done Registry cleaners, virus scanner's, c drive check. Alot of programs wont install aswell. Any ideas? Any help is greatly appreciated, I really dont want to do a format.... but if I have to I have to
