Never had a problem like this before- owned computer for 5 years and suddenly today it gained this momentary checkered pattern before just going blank. Left it to cool as well as checked connections, everything is as it should be however nothing- it doesn't even tell me there is no signal just nothing showing up at all.
 


I do hear the beep and i checked with other displays and there was still no image and the display i was using works fine with other systems so it definitely isn't that.
