If you disable virtualization in your BIOS, do you still get the hard reboots?

I'm also suddenly experiencing sporadic reboots or shutdowns on RS780 in
various graphics applications, possibly after flipping virtualization support
setting in my BIOS (Gigabyte GA-MA78G-DS3H motherboard with version F2 BIOS).
All problems have occurred either with OpenGL applications or mplayer (xv
output); even heavy computation does not otherwise trigger a reboot or

I'm seeing this on multiple kernels from Ubuntu 2.6.32-26 to stable,
with both xorg-edgers PPA and standard Ubuntu radeon drivers (using ppa-purge).
However, I'm still investigating if I'm just having a hardware (motherboard or
power supply) issue; this machine has been in heavy use for a couple of years.
