PC breaks when connecting an HDMI

Specs:
GTX 1060 3gb

Alright so, iv been away for a week and a half for some business and when I came back I noticed that the PC would break when I tried to connect my second monitor.

My PC has no VGA support, but I have a VGA2HDMI cable, which has worked for a year or so.
For whatever reason, when I plug it on now, the screen(s) go black and the fan starts spinning at the speed of light, keyboard, mouse, power button and all else suddenly stop working.
I had to shut it off manually by unplugging the cable, which has done its fair share of damage to my system (some apps appear to be corrupt now).

Does anyone know how to fix this? Im updating my graphics drivers as we speak, but I doubt it will be of much help given that my current drivers are the same as they were before I left.

One major factor is that you are supposed to power down your PC completely before inserting any HDMI cables meant to be used for video.


However, if that fails, try re-seating the video card:

If you have integrated graphics on your PC, test that first to see if it is not any of the connections on the video card.

Also, find another HDMI monitor and see if that works to make sure it is not the TV.

If both fail it is probasbly a cable problem or a problem with both.

You might have a loose GPU that is moving around when you plug the cable in.

exactly i never heard of that haha, i mean i heard about its better to power off, but on my old dell, id unplugg my hdmi 10 times a day from the pc to my ps4 and no problems.

To be perfectly honest, im currently away on a trip so I cant test any of the fixes right now, I just tagged as solved because I didnt expect any other answers.

It is a method and means of making absolutely sure that the HDMI port is being detected by the BIOS and being used by the video card at startup. Besides, I actually did in fact suggest re-seating the video card first if that did not work...

In the case of a PC tower and a PCIe type video card. you run the risk of inadvertently unplugging the card from the databus while fiddling around with plugging in the HDMI cable...or any cable really. That could cause the system to behave unexpectedly. (in Windows can cause the BSOD) and may even cause severe corruption. Given the OP's problem it totally makes sense to shut down one's PC to reattach cables properly.

The BIOS has nothing to do with detecting a device connected to an HDMI port of the GPU.

Reseattng the GPU might help if the system didn't detect the GPU properly. But this system is crashing or failing badly when the GPU is moved (my guess). That isn't a reseating issue. That is a loose GPU.

exaclty, my motherboard has a gpu lock on it
