Soltek Qbic malfunctioning...

[PiSquared]

I have an Athlon64 Qbic system with a 3400+ processor that I built for a friend. It's wonderfully fast, but it keeps rebooting at random. The blue screens of death usually reference IRQs or a page fault. I have reinstalled software and eliminated any problems on that end. If anyone has any suggestions as to how to find the exact problem, I'd appreciate it. My initial guess is that it has something to do with the memory or with the barebones system itself, but is there any way to find the exact cause?

Thanks for reading this!
