New Build Problem

noob · 24 Feb 2006 at 16:38

I've built my PC although when I switch it on it can stay on for a few minutes but then it knocks itself off. I've checked the CPU temps in the BIOS and all seems fine. When it does knock itself off sometimes you can switch it on and it lasts a minute or so or it switches itself off straight away. Any ideas?

Specs are:-

Asus A8N5X nForce4, GeIL 2GB (2x1GB) PC3200 Value Dual Channel Kit, AMD Athlon 64 3700+ San Diego 90nm, Arctic Cooling T1 Silentium Silent Midi Tower Case - 450W Seasonic Silent PSU

Will try watching the temps when I get home.

Still doing it but what happens now is you haven't got time to look at the BIOS. I'm sure I've fitted the HSF fine. Just doesn't make sense.

Going to try what it says in the sticky removing it all from the case.

Taken everything out of the case only had the CPU with HSF, power plugged in, fans and memory and still the same problem. I've checked the heatsink is fitted ok. Only option I've got left is fitting my mates Zalman CNPS9500-LED Aero Flower if that doesn't work I'm lost.

Cheers guys. Right in the end I narrowed it down to the CPU, Mobo or PSU. I took it to my local PC shop on Saturday and today they've told me they tested all three. The mobo and CPU are dead apparently the PSU is fine. They seem to think the mobo was faulty in the first place and may have killed the CPU? They also tested the RAM and Graphics card both fine.
