Fortnite/League of Legends Crashes (Please Help)


Dec 7, 2015
Hello everybody,
I would consider myself tech-savvy but I am still not the greatest with it.
Recently I have been having some issues with my GPU that I have never had before.
First, I started playing Fortnite one day and the game randomly froze and crashed while I was dropping. This now continues to happen every third game or so the game will randomly crash in the middle of a session.
In the crash log file for Fortnite it displays this:
[2018.06.16-19.34.13:523][819]LogD3D11RHI: Timed out while waiting for GPU to catch up. (0.5 s)
Also I have been playing League of Legends, which is not a very graphic-intensive game and it started crashing just around the same time Fortnite did, also happening during the middle of a session.
Except with the League of Legends crashes I get a prompt from windows saying
"Application has been blocked from accessing Graphics hardware"
Also, in the league log file it states this:
"001337.522| WARN| An unexpected error occured; unable to reset d3d device."

I have tried so much now and my frustration continues to grow with this issue. If any of you have any insight at all please let me know. The following I have tried:

- Updating Graphics Drivers
- Completely Uninstalling and Reinstalling Graphics Drivers
- Clocking Down Graphics Card
- Took Graphics Card Out of Computer and Inserted Back In
- Running sfc /scannow In Command Prompt
- Running DISM Scan In Command Prompt

The only other thing I could theorize being a problem is my PSU, but I am almost sure it isn't as it has more than enough wattage to supply enough power to my entire computer.

Also, if anyone would like the entire log files from both games please let me know a way to supply them.

CPU: AMD Ryzen 3 1300
GPU: ASUS Radeon R7 370 2GB
Motherboard: MSI B350M Gaming Pro (AM4)
RAM: Micron 8GB (x1) DDR4
PSU: Thermaltake TR2 500W

Please help me with this issue, I am very fed up with it!
