PC crash/shutdown (after driver update)

[BatatasFritas]

So, I installed the latest radeon graphic drivers for my line of graphics cards and all seemed well until my computer randomly crashed while playing videogames. I wrote it off as a one off thing and didn't think much of it, after that some of the more demanding games started to randomly freeze for like a minute or so but they would return to normal, thought it could be some optimization issues or whatever didn't make much of it either. A week goes by and it just starts crashing whenever i open a game so I start looking into it, uninstall the drivers install a more stable version but it keeps happening, after that i thought it might be a PSU problem so i decided to download some software to test it (don't remember the name) and it crashed as soon as I started the test, so I cleaned my PSU checked if something was wrong and it all seemed alright, I boot it up again run the test, all seems good, but the problem still stands. After that I resorted to only using one of my monitors with the integrated graphics card and it worked fine for a week or so until it got to where I am now where the computer turns on but no screen shows anything, I can't even tell if it's booting up properly cuz nothing shows, any ideias on what could be causing this or how to better access the situation?

 

Tl.DR: Graphic driver update turned to freezing turned to crashing turned to nothing showing up on any screen with any card.

AMD Radeon Sapphire HD 7950

Corsair CX 750

Gigabyte GA-Z87-HD3

By crashing you mean it would instantly power off like the cable was pulled? I would guess it's nothing related to the graphics card and it's more related to the motherboard or CPU.
 

But it's very hard to guess what could be the problem in something like this, there has to be lots of testing done to figure out the culprit, and if you don't have extra hardware to swap things around then i'm not sure you'll ever figure out what's going on, take it to the good ol' PC shop.

 

On another note, do you remove the graphics card from the PC when you test it with the integrated GPU? if not then do that.

Following. I have this same issue when trying to install the drivers from power color’s web page for my Vega 56. I get a “bad pool caller” screen notice when I install the drivers.
