The problem is most likely a heat issue with the CPU.

As the other person said, you need to check that the CPU fan is running first. If so --- and IF you feel comfortable taking the fan off the CPU, check for thermal compound. It sometimes dries out.

Lastly, get some compressed air and blow the heck out of everything on the motherboard. Hope that does the trick!

Any turn off after about a min is usually down to overheating. Have you checked the system / CPU fans? The shut down is an automatic thing to save the life of your processor. Take the side off, and switch on while looking at the fan. If it is going then it may be that the thermal compound's not making good contact.
