Thank you for your quick response.
I have run a CPU test and a memory test, both using the UBCD. I used the stress CPU test and the Windows Memory Diagnostic test. I'll be honest though I've yet to find a test that would test the chip set and make me feel comfortable about the mother board as a whole.
I tested the hard drive with the Wester Digital software, short and though.
The interesting thing is the system never locks up durning testing, not once, I only have issues in Windows.
Unfortunately I don't have another system that I can test the components in.
