Computer hangs on POST Screen *sometimes*

[Banli]

I recently built a computer for a friend:

specs are:

intel q6600 quad core
4gb AData RAM
8800 XFX GT
600W ultra x-finity psu
Gigabyte S-series P35-DS3L Mobo
750GB WD HDD
XP Pro 32-bit

The problem he's having is that sometimes the computer will hang on the POST screen. It'll display the gigabyte logo, but won't proceed any further. Generally, if he powers the computer off for a time, say 15-25 minutes, then it will boot up and work fine. I'm not exactly sure what the problem is as it is not always consistent which makes it slightly harder to diagnose. What should I do?

sounds like a thermal setting was set wrong in the bios.

or the HDD timeout is too short.

Did the problem exist from when you built it?

Does he have a number of USB devices hooked up to it?
