Computer freezing randomly

[Rishav_98]

Recently I changed my motherboard, smps and hdd and since then the pc is suffering from random freezing every 20-30mins. After that the computer has to be powered down before using it again. I checked the crash dump but its empty i.e there is no teport of the crash.
My specs are
Intel core 2 duo e8500
Gigabyte nvidia 730
2*2gb ddr2 ram
Enter mb-945 motherboard
Zebronics 450W SMPS
Western Digital 250gb sata hdd
A94 cpu fan

They all are older components. It could be the PSU, the motherboard or the GPU. I'd first test with a different GPU, then a PSU and finally replace the motherboard if the issue still occurs.

The psu, hdd and motherboard are brand new. I did a stress test on the ram and it's ok... While the Intel processor diagnostic tool, the processor failed in "brandstring" and "cpu frequency" tests. Is that what causing the problem?

EDIT: I tweaked around the startup services and bios and now the problem seems to happen only after 2-3 hours and there is crash report with id 7001

Is there someway to test the gpu?

Remove it and connect the monitor to the motherboard.

Ok....so an interesting thing happened. I exchanged my gpu with my friend's (Nvidia 210) and it is working like a charm... Now here's the interesting thing: he too was suffering from the same problem, albeit not frequent as mine, and he hasn't suffered any crash on my card. Similarly I too haven't suffered any crash on his card. Go figure.

Try to switch them again to see if then issue still occurs.

Now it doesn't boot at all.... Guess the motherboard was bad:-(

What happens if you remove the GT 730 and connect the monitor to the motherboard? Nothing at all?
