Windows 7
Asus crosshair v formula
AMD FX 6100
GTX 580
BeQuite 750w

Upon wake, Msi afterburner and specy, no longer display GPU Readings - MSI Afterburner reads null for voltages, temp and speeds. Speccy displays: GTX 580 and some weird character.
This has never happened before and there's been no changes, that I'm aware of.

Searched tomshardware and Msi forums, can't seem to find a solution.
Does anyone know of a possible Windows service, which would affect this?

Appreciated.
