G'day Joan,
if there are 2 memory modules take one out and try to run the tests (booting from the CD you've made - the tests run immediately with no need for intervention from you - if there are faults they get shown in the lower half of the screen - they will take a while to run). You don't need windows installed to do this. If you get failures, swap the memory modules so you test the other one.

If you still get errors move the module under test to the other slot, and finally swap the modules again - this will test both modules individually in both slots. You should be able to determine from this if you have:
a) a faulty module
b) a faulty slot
c) something else wrong.

It is unlikely, though not impossible, that both modules or both slots are faulty. If things do appear that way then the motherboard is more probably at fault.

If a module is faulty then a replacement is not that expensive. If a slot is faulty then the largest module that will work in the other slot is also not that expensive. If it is the motherboard I wouldn't waste any further time...

You're only paranoid if you're wrong!
