Hi

I have recently built a PC for the first time. The key components are as follows:

- Intel Core 2 DUO E6300 "LGA775 Allendale" 1.86GHz (1066FSB)
- Asus P5N-E SLi nForce 650 (Socket 775) PCI-Express DDR2 MotherboardGeIL(Bios 0401)
- 2GB (2x1GB) PC6400C4 800MHz Ultra Low Latency DDR2 Dual Channel Kit
- Tuniq 120
- BFG 8800gt 320
- Couple of amber fans
- Seagate 320gb hd
- Windows Vista

I overclocked it to about a 450 fsb, adjusted some of the voltages and adjusted the memory to 4 4 4 12, all per guides and advice on these forums (ran Orthos for 12hrs on more than one occasion). Everything seemed ok and the temperatures were fine until recently when everthing on my desktop would freeze every so often. It could be after 3 hours or it could be after 10 mins. I could still see the desktop but the mouse wouldnt move and the keys were unresponsive. Each time I have to reset by using the power button.

This morning I decided to reset the Bios to factory defaults but my my desktop froze again after about 30mins.

I am at a loss as to what could be wrong (could it be Vista??). At moment I am running memtest but as yet have no errors at 21% coverage.

Any help would be appreciated.

Thanks
 
Does it freeze if its just idle on the desktop? or is it always when your doing something, stressing cpu graphcis etc? What power supply are you using? And all the temps are ok? Try taking everything out apart from the bare components, mobo cpu hdd ram and see if that helps. if not have you got spare components lying roundyou could swap some bits with and error test different components.

I actually had a very similair problem recently where comp you freeze BSOD etc, anyway after a while it turned out to the RAM. (Got it replaced and it was still doing it, turned out the RAM they replaced it with was faulty as well, nearly drove me crazy figuring that out, anyway all works now.)
 
It's actually normally when the PC is idle with it only downloading something.

I have an OC 520w PSU.

I do have some spare components I could swap in so I might give it a try.
