First, my system specs:
Medion MD42200 Laptop
Intel Centrino M
ATI Radeon 9600 Mobility
I recently reinstalled Windows since it was getting sluggish - Desktop operations and things like Web browsing were affected, Games still ran fine. After the reinstall, the Desktop stuff is better. However, there is a new problem. 3D Games (such as GTA:SA, Racer) will periodically freeze for a period of 1 to 5 minutes. I did an update of the video drivers, which didn't help (and I was using the ones that I got on CD before the reinstall and those worked fine anyway).
I did a few more tests to gather what happened. I set up my TV as a second monitor, and had the task manager on it while I was playing GTA:SA on the main screen, and had a clock next to my monitor. The freezing happens every 3-10 minutes, during which time the computer completely freezes for about 1-5 minutes. Sometimes, the task manager updates just as the freezing starts or in the middle. I told the task manager to sort by CPU useage, and during the freezing, the System process was using something in the 90s range of %CPU. The same thing happens with Racer, except that Racer drops to an FPS of about 0.5 instead of completely freezing (probably because its not as resource intensive). However, even then things like Ctrl+Alt+Del, Ctrl+Shift+Esc, the numlock key, and all those intresting key things don't do a thing.
Thanks for your help ahead of time
