New Build P4 (775) Power Down

Howdy all,

Building a new P4 with a Socket 775 Processor. Using a FoxConn board (new). Have done all of the prelim stuff, installed drives cab jumpers, CPU Cooler, IDE Cables and all power connectors.

The computer boots to Bios, I get a Post Beep but about a minute into setup, the power dies. This has happened partway into a WinXP install, it happens if I let the computer sit on the boot screen.

First thought was bad power supply, so I swapped it out with another I had. Same thing happens. Any Ideas?

Grif, Did apply the paste. This is a bit new to me. This is the 3rd new build, and never had one do this. The system stays on as ling as I am in BIOS. System health says CPU id sitting at 82-83 Dgrees C.

Now this socket does havs something different. There is a metal retaining clip that is between the CPU and the Heatsink. Should this get thermal paste on either side?

82 Degrees C is Too Hot..

In reply to: Yup!

...and it's a good possibility that the symptoms you're seeing are related to heat.. About 30 - 35 degrees C is more appropriate. I'm guessing you don't have the processor, heatsink, and thermal paste correctly applied and working as designed. Only a very thin coating needs to be applied. The retaining clip doesn't need to have paste on it..

As to specific instructions for applying the paste, the link below might help:

Hope this helps.

Thanks everybody, all is well now. One issue was that I had the dangdest time getting all 4 legs of the Fan mount to lock in, so the contact between heatsink and processor suffered. Thinning the paste application, locking the legs and whango! off and running.

I do like the lock on the older skt 478 P4's a bit better, but things change...

Now on to my next crisis!
