I really don't know where this should go, but it involves RAM.
Basically, I had 512mb RAM and although my PC ran OK, I upgraded to 1gb. Now, whenever I do anything like open a flash video in full screen or play a game, the fan goes mental and makes a loud spinning noise continuously. Before I changed the RAM, the fan was silent. So, if I leave the application open long enough then eventually my computer cuts out.
Help, please. I can't play games anymore. :(
