Bit of a long one here so please bare with me.
A few weeks ago I upgraded my PC/sim rig to Windows 10. All was well. However, a few days after the install I booted up the rig, went for a brew, came back to the rig to find a black screen. Thought the rig had gone into sleep mode but nothing I did woke it. I was moving the mouse and pressing the space bar etc but nothing. I then just started pressing buttons on the keyboard and heard the PC come back to life but still had a black screen.
Anyway, after trying various things I unplugged the DVI cable and connected the HDMI cable... success! The PC came on and so did the monitor. Using the onboard graphics was/is fine. Everything is working as it should so I know the monitor is working and everything else (power supply etc) but when I try to use the graphics card with the DVI cable I get nothing. I can hear the PC booting up as normal but there`s no "beep" and all I get is a black screen. After a wee while with it sitting on the black screen a little moving box pops up on the screen saying something like "HDMI not connected/No Signal To Monitor".
So the long and short of it is that when I connect up the graphics card with the DVI cable I`m getting the black screen and I can`t access the desktop in any way. When I connect the HDMI cable and use the onboard graphics everything comes on and works as normal.
Not an onboard graphics kinda guy but at least I know everything is working using that.
I`ve removed the card and cleaned it/reseated it etc and have checked all the connections. The fans on the card are coming on and seem to be working as normal. Checked all other parts like RAM etc too. Everything seems to be connected/seated properly.
I re-installed the W10 OS to see if that "cleared" anything but it didn`t.
I`ve also checked in the Bios and it`s set to PEG which is the card.
I`m thinking it`s either a faulty DVI cable or a dead card but thought I`d post here to see if you guys agree with that or if you have any advice on anything I can try.
Btw, the card is a Gigabyte GeForce GTX 780 OC 3GB.
Complete system specs are:
Intel i7-4770K @ 3.50GHz
Corsair Vengeance Pro Red 16GB DDR3 1600MHz
Seasonic M12II Evo 750w
Corsair Hydro H100i
I`d be interested in any thoughts on this.
