@jasonvr: Were I you, I'd still review (and keep an eye on) the event log (system) for errors indicating hard drive and/or storage controller (SATA/IDE) issues. When BSODs that you see under heavy CPU and I/O (hard drive read/writes) loading aren't related to heat issues alone, they often indicate a "weak" component. IME, that usually means a hard drive that is on the verge of failure, an I/O component whose drivers are outdated (specifically storage controller or motherboard chipset drivers) or whose hardware and/or drivers are generally "not up to snuff", or a weak memory stick. Or, of course, overclocking beyond the system's capabilities or without ensuring enough CPU or memory voltage.

I.e, it is wise to translate what is effectively failure during a "burn-in" period of heavy loading as the potential for a failure under lighter loading, just as you would translate a horrible noise coming from your car's engine when you accelerate rapidly as a signal to check for a condition that may leave you stranded by the roadside (out of cellphone range, of course) at some later date.

(Edit: To rule out memory stick issues, you might consider using the software and instructions available at http://www.memtest.org/ to create a bootable CD and test for same.)
