Windows Crash/Shutdown While In PT001

[Sounder]

Ever since I loaded Didgi001 my computer crashes and goes into re-start mode. After much research and tech help I've narrowed the problem down to Pro Tools. Is anybody else having this problem or know of a fix??

My PC sometimes shuts down, but i think it is a power supply issue, because i have 3 HD, a Viper video card, 2 memory modules, wireless net system, and digi001. My power supply is 300w, i think it is not enough.
I will buy today a 400w power supply and i will send to you the results.

Please do. I've been told that this might be the problem, but I only have the digi and a USB port conected AND I just replaced my power supply last week. Still does it when using digi.
