So yesterday my Computer Restarted when I was on, well il be honest here a Adult Website. So I came back on, GPU was not being detected, dual screens no longer worked and when moving lets safe the browser window about it would sorta laag and "erase" desktop icons (they would come back after few milli seconds). My Avira is unable to be turned on, Realtime protection is offline and status message "computer not secure" appears. My Sleep and Hybernate modes are greyed out as well as "Realtime Protection" for Avira has the same. Lastly Nvidia GPU panel gives me the error "NVIDIA Display settings not available. Your are not currently using a display attached to an NVIDIA GPU" Also DXDIAG has said the same, N/A for the GPU tab so basically GPU not being detected, even Everest says the same. I re-fitted the GPU, cleaned out the machine so I guess either W7 reinstall (move the old one to windows.old for backup) and or BIOS flash for my mobo (but my amd 555 be needs to have one of the latest BIOS revisions). This is really odd, did Spybot scan and removed double click issues but that isn't anything to do with this. Started in Safe Mode + Reinstalled my GPU drivers with latest and oldest drives too. EDIT: Looks like in the Device Manager, it detected my GTX 460, here is a screenshot.
