Funny video, but the only crashes I have experienced in Vista I experienced is when the CPU says OHSHI when I try to overclock over 3GHz. I do up the voltage, but it just seems to crash at 3005 MHz.
Also, to get rid of those annoying "Allow or Block" prompts, go to Control Panel>User Accounts and Family Safety>User Accounts, and click "Turn User Account Control On or Off"
After you disable it, restart your computer. No more prompts every 3 seconds!
