PLEASE HELP!(Motherboard)

I would checkout some used combos if they're cheaper; you may have a problem with your cpu and you won't know until you try another board. With such an old cpu, a new motherboard isn't worth it. Lots of good g31 boards; just check the "cpu support" section with your cpu model number on the lid before you order.

First of all, THANKS a lot for your quick reply.

I recently had went to my local vendor, to change my SMPS. He only told that i need to change my Motherboard some time later.

The PROBLEM in my PC is, that it is normally working well for 15-30 min, then there is a sudden restart. then it works for 15 -20 min , and after that it restarts again.
I would really like a conformation from your side, if u have idea, that it is a problem of MOTHER BOARD or not.

Moreover my Processor is '05A Platform compatible'. So could you please suggest me some good Motherboards which are "05A Platform compatible."

Today i will be going to INTEL SERVICE CENTRE, to see if this motherboard is repairable.

Praying to god that it is.
