Hey all,

Have a bit of an issue with my pc and wondering if anyone had any ideas/pointers?

Yesterday my desktop/gfx card started blinking out, my monitor would just go black for a second then come back on again, it started maybe doing it every 30 seconds or so I shut everything down and rebooted and same again (same when I left it off for about an hour) left it on for about half an hour and over that time the frequency increased and the screen stayed black for longer. Tried again this morning and there was some brief flickering when there was an image on the monitor but pretty much as soon as I was logged in the screen was just permanently black. My monitor goes to blue screen if it senses there's no input but it wasn't doing that so my gfx card is outputting something but just black. I took out the gfx card and plugged straight into the motherboard on board graphics hdmi out (although I've never used it before) but just got black screen again..

Any help or ideas what it might be or what to try would be great.
Thanks.
 
I agree with the above, try a new cable first, because there's the simplest fix. You could also try DP instead of HDMI.

Phew, strange wouldn't have thought of it as I don't think i've even touched the cable in ages.

A few things can dislodge them, like sitting at a desk causing vibrations and pressing the monitor buttons on/off repeatedly over time. They're often held in vertically too, where gravity is against them.
