My problem is that my pc has started to freeze on a regular basis while playing games. The screen turns black and goes to sleep mode. As all the controls stop working I have to reboot the system whenever this happens.Lowering the graphics is of no use, and since all the games used to run perfectly the problem must be elsewhere. All graphics & sound card drivers are up-to-date.
The interior of the case was freed of dust maybe two months ago so I don't think it is to blame.
No major registry errors appeared in scan either.
Here are some of my system specs, more info provided in the link http://h20000.www2.hp.com/bizsuppor...
-Intel I7 860 quad core processor
-GPU NVidia GeForce 230
-8GB of memory
I have observed temperatures and such via HWMonitor and Speedfan and it seems that my gpu temp is 80 degrees C already at startup and reaches 100C in less than 15mins. I also did a test on Furmark and after 2 minutes the gpu reached 105C and the computer shut down.
In summary, I think the gpu idle temp is strangely high but I've read that these kinds of problems can also be caused by failing psu. I would appreciate any help and views on this. I can provide the HWMonitor data if requested.
