Pc freezes completely after 10 minutes of playing games

Specs: Windows 7, HPE-130sc 2.8GHz / 8GB
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.

Open the system case and make sure all the fans are actually spinning when powered up, because your temps are definitely way too high.

Remember the fan that you can't see - the PSU fan. You can just about see it through the grille at the back. If that's not spinning, fit a new PSU.

Thank you for reply and the hint. I checked the fans, they do spin. Also, according to monitoring softwares, the other fan spins at 1000-1800 rpm and the other at 1100-1200 rpm.

I don't understand much about the whole psu thing but the voltage values are following, I'm not sure, though, if they are of any use.

Voltage 0 1.65 Volts [0xCE] (VIN0)
Voltage 1 1.65 Volts [0xCE] (VIN1)
Voltage 2 1.62 Volts [0xCA] (VIN2)
gpu voltage 0.950 Volts
