Computer down

I am typing this from my wife's laptop as my PC is currently unavailable. My CPU fan has been making noise for a while and I knew I was going to need a new one. Today the power went out in my house for about 30 seconds and it took my computer off. When I restarted it, I kept getting an alarm saying that the fan was not running at a fast enough speed. After striking out at Radio Shack and Best Buy, I am going to have to visit a computer repair shop, possibly as soon as tomorrow. I may check in from my wife's laptop before I get mine going again.
