No video out - intermittent problem

[damianpaul]

Hi, I wonder if anyone can help please. I have posted in general as although I suspect it may be graphics card related it could be something else.
I built a new PC earlier in the year but have been having an intermittent problem. Approximately 50% of the time the computer boots but there is no signal displayed on the screen. The computer does boot into windows and I can connect to it from other PCs (e.g using Steam in-home streaming) but the screen remains black as if no signal is being received. I have to power cycle the PC multiple times until it starts working.

The motherboards on-board graphics works without fault 100% of the time.

I have tried the following
1) Cleared CMOS (removed battery 30 mins etc)
2) Reseated all hardware on motherboard
3) Tried booting from one stick of ram in various slots
4) Tried all 3 PCI slots on the motherboard
5) Tried different HDMI cables
6) Updated to latest bios
7) Tried different output from PSU to the graphics card

Worthy of note is that this problem occurred from the very first time I used this graphics card. When no signal is displayed on the screen the fans on the graphics card do spin and the lights are on.

When working the computer is rock solid stable - it can run prime95 on blend for as long as I've left it (12 hours) and can play modern PC games for hours on end.

Does anyone have an idea of what the problem could be please?

Cheers

Are you using the same cable for both the onboard and the 960? Have you tried a different port/connector on the 960 to see if you have a faulty port on the GPU?

Hi, same cable for onboard and 960. Haven't tried the other ports as I only have hdmi input on the screen. Can you get converters?

Ive RMA'd my graphics card and no fault has been found. Could an issue like this be caused by the psu?

What display are you using? Do you have any other connection options like DP or DVI?

What monitor are you using?

Very much doubt it's the PSU, but it is possible I suppose. Sounds more like that particular monitor and video card combination is just fussy. I recently had a Dell laptop that had a very similar problem to yours - it ended up having a whole new motherboard fitted and still had the same issue.

Is the monitor a TV by any chance? I had an issue before on a media-PC and a firmware update on the TV fixed it.

Thanks Curio.
I've tried the DVI output and same problem.
It was interesting to see your comment about issues you've had as I am using a TV. Just tried updating the firmware but it didn't help. Also tried another TV and, again, still has the problem.
