Hanging programs

I guess that someone on here has had the same experience that I am getting...I bought this Acer comuter on 9/23/10 and have been having problems with it off and on ever since.

It will freeze for about ten seconds and then resume again when I am on the net...I also do a lot of Flight Sim flying and during almost every flight the computer shows a plain Error message and shuts me down to Desk. Shutting off the FSX in the process.

Yesterday I made a backup of my files and the DVD would not open to let me remove the disc???????

Merry Xmas and a Happy New Year to All. Except Acer..... any help would be regarded as the best Xmas present ever...Phil.

I will give that a shot thanks mate!
