Sorry, it's a Sony VAIO laptop, about 3 years old. I run Windows XP on it. It began two nights ago when I was on the internet and then an a small gray error box would pop up saying something like "Cannot recognize (something)" I forget what it was but after that a bunch of IE popups would fill up my screen and then like a minute later they would disappear. This happened about five times, then the computer freezed and you know when computers freeze but are able to unfreeze? This one wasn't it just froze. So I decided to unplug the battery and restart it. When I tried to restart it the lights of the computer went on, but the screen would not turn on or anything, it looked like it was still shut off. I don't know what to do because I can't fix the computer if it doesn't even turn on...you know??
