I have a new box with the following.

CPU: AMD Athalon X2 7850
Motherboard: Gigabyte MA770-UD3
RAM: 4 GB DDR2 Kingston
Graphics: Sapphire HD 4670 1GB DDR3
O/S: Windows 7

Everything seemed to be fine for the first week or so. However yesterday I installed Company of Heroes and on playing it only for afew minutes the PC shutdown itself. On restarting it again shutdown midway through windows 7 startup.

I went to the bois and saw the CPU and system temps. The were 46C and 38C respectively. No problems there. I waited for a while and started again. This time i had a successful startup. I monitored the GPU temperature and it was around 60C with fan speed 40%.

I fired up COH and after playing for 5 minutes paused and looked at GPU temperature -- it was 104C with fan speed 100%. It gor down to 94 in 10 seconds. I switched to the game again and the system shoutdown in 15-20 seconds.

What's going on?

I had a three year old IDE DVD writer which i put to use in this. Could it be that the IDE ribbon cable is obstructing airflow?

Looks like a temperature problem in the GPU. Try it with the case open.
