"I was switching out the antivirus software I had on it"
Do you mean turned off your antivirus ? if yes then what type of antivirus program u were using
"I tried killing the programne I had up"
What type of program .. and how did u killed it? by deleting you mean?
Did you tried rebooting after like a hour ? How did this problem exactly happened? like what did u exactly do when this type of problem occured suddenly at that time.. ?
Also give me full specs on your laptop, i want to know what processor is it running as well as RAM .
Solved the problem. It was AVG that I was trying to uninstall. I'd already installed the replacement programme (Avira). When AVG froze up, a little window popped up and said AVG was unresponsive, and asked if I wanted to kill it (close it/stop running it) or wait for it to respond. I kept hitting the 'kill' option, but nothing happened axcept for the same window popping up over and over again. Finally the AVG window I had up (the one I was trying to close) disappeared, but took my taskbar and desktop icons with it. That's when I tried some keyboard controls (which didn't work) and then hit the power button, which shut off the screen. The computer stayed on for a while after that, but it finally shut off and after about half an hour I turned it back on and it was/is fine. I'm thinking it maybe just overheated (it's big and slow, and tends to get hot). The computer has an Intel Core i5-2520M CPU @ 2.50 GHz and a 64-bit OS (running Windows 7).
