hey there,
I'm mining with with an Ati Radeon HD 5830 (core clock 965MHz, memory clock 300MHz, VECTORS AGGRESSION=8), with a PSU of 420W. My problem is that if press ALT+TAB when I am mining and I want to switch from *someprogram* to Excel the ati driver crashes. Anyone noticed athis strange behavior?

I'm looking forward for your answers, thanks.

EDIT: it happens almost every time i press alt+tab
