So I was peacefully dusting my room, when I moved the rig back an inch or so and moved it back, paying it no mind. However some sort of fault has developed? I was playing it just the night before, but when i tried to switch it on the no video input error comes up. I've tried removing the ram sticks, changing hdmi cables, and even tried different monitor, but nothing seems to work, so I assume it's the problem with the actual rig? Any further help could be helpful, before I contact the useless IT support.

Oh I also forgot to add, this sort of problem has occurred in the past, not sure how I've fixed it though, because it seems to have started working of its own accord, the rig doesn't make any beeps whatsoever when I turn it on, so I am at a loss. My hdmi connection is also having to use the mini adapter to adjust to the video card output.

Try changing the cords to the TV or use on a different TV. Need to narrow down the issue to actually being the "rig".

Yeah super, I mentioned different monitor and HDMI cable.

Try pulling your video card out and put it back in.

Mine once moved out slightly when i moved my case and I had that error.

Alternatively try a regular VGA cable as it may have defaulted to that so need to switch back to HDMI.

On one rig that I had when I upgraded video cards I would also get that message until it actually loaded up into windows then my monitor would come on lol. No idea why, could never work it out.

I would also try another monitor, and another PC on that monitor to eliminate any video card or monitor issues.

It could be driver problem. Have you tried booting into safe/recovery mode?

Ok I think the problem is the adapter, I took it out, swirled it around, slam dunked it into a bin and got a new one, now I've connected it, it's fine. I thought it was the video card failing or something, but I found it weird that my card would be failing just because I've decided to dust my room and move it like 5cm.

Thanks for the help anyway guys

glad you got it fixed :)
