My pc Screen goes black after 5-10 minutes of usage.i thought it was due to old graphic card drivers.when I updated graphic card drivers,screen gone black after reboot and now i cannot even use for a second.
When screen goes blank, is it during normal usage and/or idle? or during gaming?
My thoughts are either your PSU cant handle your Video card or the card itself is bad? you said you tested with another video card and it was working fine correct?
