Computer Gives Up The Ghost

My computer has finally given up the ghost. It has been making this strange beeping noise for the past few weeks when I try to turn it on and I've been just too lazy to find out what what the problem was. You could usually unplug it from the back and then plug it back in and voila you were in business but yesterday...no such luck. I dropped it off yesterday afternoon but haven't heard back yet. I just have a feeling the news ain't gonna be great. Luckily I can access the internet from my daughter's computer so all is not lost but I am trying to remember if I backed up my lastest works. I'll keep my fingers crossed.
