Hello everyone, I have a Sony VIAO running windows 7. The laptop is about 3 years old I believe. I'm having an extremely strange problem that seems to have no solution. About a year ago, one day out of the blue, the laptop went crazy. I would try to type something and whenever I pressed a key, it would pull up random programs and send commands and type multiple letters at once. Then the screen would get all laggy and the fan would come on full blast. It was completely unusable. I tried restoring the system and resetting a few other settings (don't really remember what all I did a year ago) and nothing seemed to work. Then one day, once again out of the blue, it was completely normal. And it stayed normal for a year, up until a few days ago. It's now doing the same thing. Does anyone have any idea what's going on? Every so often when I start it up I'll get a black screen that says "operating system not found" and I have to pull the battery. When I turn it back on, it's fine. Is it possible that reinstalling windows would fix this issue??? I'm so lost.
