Fortnite crashed after a few minutes after I swapped motherboard?

Yesterday I installed my motherboard (P8Z68-V LX) and a new graphics card (RX 580 8GB) now I get blue screens from time to time (my PC crashes with error messages like WHER_UNCONNECTABLE… Iwas) and fortnite can't start, or I can start but after some time crashes fortnite.

What can I do?

would a BIOS update be helpful?

Either the graphics card broke during the process. If you have an integrated GPU in the CPU, then plug the screen into the other HDMI socket and try it out. If it works then the GPU is broken. Otherwise times m BIOS look, if all HArdware parts such as RAM etc. Are recognized and work. Possibly. Also the monitor broken?

Reinstall… Or use the "clean reboot" feature. There may be conflicts between drivers.

Alternatively simply reinstall the current drivers for the mainboard. Uninstall ALL graphics drivers and install the latest one from the AMD website.

But it can also be on the cooling or the power supply

How do I uninstall the old or all drivers?

GPU is not broken, can see the drivers and just fortnite again could briefly play on 180 FPS completely epic

Sorry but with a RX580 you can't do 180FPS on Epic in Fortnite. Then look, if more recent drivers of Graka are available and download, if so. Otherwise motherboard probably broke, sometimes in bios look

Download DDU

There are a maximum of 180 FPS and have a few things like shadow disabled

And then?

A possible cause could also be a not properly mounted CPU cooler (you have just changed the motherboard). Then there are thermal problems at high load.

The Event Viewer then shows "Kernel Panic" under administrative events.

If the blue screens come through the graphics card, usually an error with "Nvidia" or "AMD" is displayed.

A defect in the graphics card can also lead to time-delayed errors and must not occur abruptly.

What should be understood by not reasonably mounted CPU cooler?

have water cooling from Corsair and did that earlier so the Corsair has shown to the right, now it shows right,

Is it possible?

If the radiator body does not sit tightly enough, or too little or too much thermal grease is used (or even forget to remove the film from the heat sink), there's a heat build-up despite high-performance radiator.

I do not know any special installation instructions for AIO cooling, but I only have experience with air cooling and "correct" water cooling.
