Since a couple of days I'm experiencing freezes and crashes. This has only happened while playing (3D) games. Sometimes the music player keeps on going in the background when the game freezes up, but shortly after everything just stops responding/acting.
Only way to reset the computer is by using the reset button. Keyboard input doesn't do anything.
The use of benchmarking utilities gave no errors or low performance. Updating drivers didn't solve the problem. Nothing has been changed in my system (hardware and software) in the past few weeks. There are no problems with my harddisks (checked that). It's not internet related (gives freezes while connected and not). I'm also running both Windows XP and Windows XP x64 on my computer. Both give the problem.
The problem seems to occur during a lot of graphical activity (which also relates to a lot of game activity). So I'm guessing it's either my graphics card or my memory which is faulty. I have no spares of either (only computer with these types of hardware here) so I cannot swap these out to test them. Any idea on how to test either? Or any ideas on what the problem might be?
Thanks in advance.
