So sometimes in certain occurrences my monitor will go go black then into "power saving mode," then after a solid minute or two it'll turn back on with awful lag. Then till I restart it, the computer will freeze every 5 seconds. The only real times this happens is when I play LOL. It doesn't happen with any other games as often as it does with League. I thought the spiking was a power issue and lack of wattage so I replaced my old PSU.
Here are the things I have done:
Reset my drivers(most of the ones u would be told too)
Reinstall windows 10
Change location of files
Undervolt and Overvolt my GPU
Reset monitor to factory settings
Check GPU fans
Higher Fan speed
Buy a new psu
Here is the important stuff of my build
b450 Aorus elite
Ryzen 5 3600
Radeon RX vega 56
Has anyone ever had a similar issue that can help?
