Is the memory 1gb or 2gb sticks? And have you tried it with just one stick?

And how far does it get before resetting?

memmory is 2 x 2GB sticks

3 seconds roughly

So on the POST screen? Atleast that rules out an OS problem.

Try it with just one stick of memory. If that doesn't work then try with just the other stick.

Is the graphics card the only 'old' component?

I take it you have already tried resetting hte cmos?

Try the system outside of the case, The motherboard may be grounding somewhere.

Have you connected all your motherboard power connections?

What voltage does your memory need?

talked to supplier who went through the same stuff I was trying
