I am building a new computer using an asus a7v600-x motherboard, amd 2800 333 athlon xp, and 512mb pc3200 dram. After power up it goes to bios screen and shuts down usually after 40 second or less. I have reseated the cpu and it is making contact with HS. I have swapped out PS. I have 2 80mm case fans. this is not my first build. Any suggestion?

When a computer turns off especially on computers just built its usually due to power or heat.

You say you have changed the PSU and made sure the HS is in contact with the processor. Are you using any Thermal Compound?

definately used thermal paste. It all seems to squeeze out so, I loosened the clamp to keep a layer on the core. I even tried different HS.

Oh no, have I read that correctly? - you loosened the spring clip that secures the heatsink? NOOOOO!

The only reason for the thermal paste squidging out is because you have used too much of the stuff! Using too much can be almost as harmful as not using enough.

If the cpu still works at all, I suggest you clean the remaining paste from the heatsink & cpu using a special antistatic cleanser. Reapply a fresh blob of good quality thermal paste - just place a pea sized blob in the centre of the cpu then spread it over the die so it's covered in a thin film of paste. Reattach the HSF (as long as the clip hasn't be bent out or altered), connect the fan & fire the system up.

reapplied thermal grease, same symptoms.

If humiliating myself in public will fix the problem, I don't mind at all.

That's why I'm asking for help. If I knew the answer I wouldn't be here.

Just out of interest, can you check the temperature of your Cpu in the bios before the shutdown? That would show if the problem is heat or not.

Hi,

Are you sure the HS is mounted correctly it is possible to mount (rotate) a socket A HS 180 degrees in the wrong direction. This is a common mistake, make sure the stepped portion of the HS is facing the part of the socket that says 462.

Make sure the HS is compatible with socket A
