hes prolly means 93*F if u turn that to celcius its only 40 to 50 right? witch is normal.
i would rule out any softwear problems b4 messing with the hardware.
if there isnt anything u need on your pc, just reformat and reinstall windows.
go to... control panel/system/advanced/startup recovery settings/disable auto restart.
control panel/folder options/view/turn on 'launch folder windows in separite proccess'
--------------------------------------------------------------
if u dont wont to reformat.
scan pc with Spybot S&D, Adaware, and a anti virus prog.. AVG antiviruse is Free. along with the rest.

also if there are more unused power connectors on your UPS(power supply) substitute the unused one for the one u currenty are using on your Radeon.
