I have a system with a Biostar G31M+ motherboard and an Intel Pentium D945 3433MHz (17x202) processor with Intel Bearlak G31 Chipset. The system is overheating and I'm trying to figure what I should do next. The CPU fan is spinning. It originally didn't have any thermal paste between the heat sink and the cpu so I added that but it is still overheating. When I use Speedfan the temps read at 77 degree and 78 degrees celsius when the CPU's are at a load of 50 to 60%. If I try to do a system stability test with AIDA64 it will overheat and shutdown in like three minutes. Any suggestion on anything else I should try before I go get another CPU or system? It currently has a factory CPU fan and heatsink and I mean I don't really do anything on this system but word process and surf the internet and it can't even handle that if I get too many things working for a long period of time. When I though it might have been a memory issue it didn't crash once when I ran memtest 86+ for 8 passes. The CPU fan was running at 3050 rpms during the stress test but it still crashed. Anybody have any ideas as to what else I could try or is it just a bad CPU or what do you think? All help is appreciated. Thanks.

The case seems to have alright airflow, however, the only fan in the case is the CPU fan. There is a place to attach a case fan on the case but I don't see a connector on the motherboard to attach one. Previously there was no thermal paste. I applied some and I was always to not put it on too thick. Thus, I applied just enough to have a thin layer that completely covered the bottom of the Intel heat sink. I used a gift card to spread the thermal paste in a thin layer.
