PC Locks up for a bit After Closing Fullscreen games

[RedxYeti]

So when I start a fullscreen game it causes my computer to hiccup a bit and then continues, but when i close the fullscreen game it locks up for upwards of 15 seconds. its been doing this for a bit now and its starting to get fairly annoying.

 

Running games borderless window or just windowed doesnt cause any sort of lock up

 

during the lock up my 2nd monitor goes black 

 

specs:

z390 e gaming (asus)

i9 9900k at 5ghz (4.8 atx)

1080 strix (newest driver, just did a ddu reinstall also)

32 gb hyperx 2666 ram

kingston nvme drive

win10 pro

 

if you have any suggestions or you need more info let me know, thanks.

So you're not going to turn off the overclock when doing diagnostics?

Two things to do whenever you get any sort of inexplicable PC problem:

 

1. Undo overclock.

2. Disable XMP.

 

Try both of those then come back to us.

i get better thermals with the atx on while OBS is running but it runs fine at 5ghz.

 

is this relevant to my problem?

yeah , you never leave an overclock running on a machine that hardlocks and try diagnostics without disabling it.

If your machine can't handle the arduous task of full screen applications then it's not stable is it?
