abit post code 0.4 (boot up failure)

My pc was working fine - I decided to upgrade my heat sync.

Having replaced the heat sync and reconnected everything back to the motherboard I booted up my pc. After around a second the PC gave one long beep which repeated. And the abit post code showed a post code of 0.4.

The solution was to remove the heat sync, take the processor out and put it back in, replace the heat sync and try again.


I hopes this helps some body.

Looks like a fairly common problem..... those ABIT people came to a strange conclusion though.

 

When reading the Abit thread I can see how it would happen, if you had not enough standoffs between the mobo and case or maybe even if you did, when applying pressure to mount the hs you short the mobo or flex the mobo to a point it could cause problems. Not sure what the error code is or how taking the cpu out and reinstalling it fixes the problem.

I guess my point is that when installing a hsf it is better to do it before the mobo is installed in the case on a new build but if you are just replacing I guess you take the chance.
