I get frequent display shut off with "no signal - Entering power saving mode", the PC seems to be still running with GPU fans spinning...etxc, but the screen is off. 


I tried:

High performance mode

multiple outputs from the video card

default settings in bios

no OC

ram test by windows

multiple games

multiple radeon drivers

updated the card bios! 


all temps are normal. 


what couls be the case?
