Hey Hykster
I'm having the exact same problem and I've been searching on the internet for a solution. Everything thing i've seen says that if you test the power supply and the 3.3v rail checks out then the problem is somewhere else. The main solution they gave was start removing parts and see if having one removed solves the voltage problem. If that doesn't work replace the Mobo. I have an Asus P4Pe and in the bios my 3.3v is down around 2.9. My computer crashes only when I run high end graphics games such as World of Warcraft. Otherwise my computer works fine. Have you found a solution cause no one knows one that I've found.
