What is it you need 2 know it is a custom pc that i made myself?

OK ... sorry, I missed that point

I would check anything new against the compatibility of the board of course.

Check the case fans ... how many are there? how many does the board support?

Check the PSU fan & the PSU itself. The CPU fan as well as the Graphics card fan.

Sounds like a PSU issue to me or perhaps Hot Wires. Run with the case open ... feel the power wires ( especially connections & splitters if you have any ... check for Hot Spots.

Make sure the IDE cables ar'n't blocking fan paths etc.

Does your BIOS have heat sensors? You can also get some with this app:
