Hi, I've been having these problems for the last few weeks. If I'm typing using Microsoft Word or I'm playing a graphically intensive game, it may happen. It seems utterly random. The problem is either the monitor going onto standby and the sound just looping until the sound cuts out, while the actual computer is still on and the fans are still whirring etc. Or, the screen just freezes and the computer is still on, but the sound cuts out straight away. As I said, I don't there is anything I can avoid doing to make this stop, sometimes the computer runs for 3 hours playing an FPS like Call Of Duty 4 and other times I will turn it on, it will load the desktop and then it will freeze straight away... It may be a temperature problem, but I don't understand why a component could be getting too hot when just using Microsoft Word. Also, it's not my graphics card because I recently clocked it back down the default core and memory speeds. Does anyone have any ideas why either of these things occur? Thanks for your time, Blekk.
