PC restarts when resolution is set

post #1 of 3
Thread Starter 
GPU: ASUS AMD HD7770

Strange thing, I had some issues with my water cooling that got stuck and raised the temps a bit but don't think it did any damage to my hardware, even though little water sipped out when I was as well trying to fix the loop. When I fixed it things worked, but then something again happened the loop got stuck and raised the temps, but no water issues this time, only the GPU resolution fault that came up after this incident.

I ran sfc /scannow no issues.

When ever I set my default resolution 3440 x 1440 my PC hangs and restarts after a while. Same issue with the Microsoft standard drivers. So now I'm running 1024 x 768.

As well when I install the AMD drivers same thing happens, because during the install the correct resolution is attempted to be set, so PC again restarts without the drivers being installed.

Very strange issue, don't think anyone have had it.

Have checked different cables, HDMI, DisplayPort but same issue.

Is it a faulty GPU or Windows 10 issues with corrupted files, or anything else?

I'm thinking about repair Windows, will keep my profile but allot of 3rd party apps will be uninstalled.

To me, that sounds like your GPU might be damaged and is doing bad things on the PCI Express bus when you change the resolution, I've seen similar things at work with the (non-GPU) PCI Express boards we manufacture if they get bad firmware or are damaged. PCI Express errors often result in a system reset.

Do you have another GPU you can test with?

I'll just have to test it.

My Blu-ray drive is now as well acting suspicious, open/closing and at the end getting stuck. When I was filling my water bay tank, little water ran down the drive, and might have caused some issues, or it's maybe the MB that as well took allot of water.
