https://www.quora.com/I-get-this-error-when-I-play-Minecraft-on-my-laptop-Application-Java-TM-platform-se-8-has-been-blocked-from-accessing-Graphics-hardware-What-should-I-do-I-just-updated-to-Windows-10-from-Windows-8 says the same.
When I am playing Minecraft, I get the error "Application Java(TM) Platform SE 8 has been blocked from accessing Graphics Hardware" usually within 20 to 40 minutes of playing on servers.
Sometimes, the Minecraft screen will turn bluish-gray (this is a different error from the one above), but this is not as big of a problem.
PC Specs:
CPU - AMD FX-8350
GPU - ADM Radeon RX550 4G
Motherboard - Gigabyte 970A
PSU - Coolermaster 500W
Monitor - Dell Monitor S2716DG
OS - Windows 10 Home
So far, I have tried:
- Running Minecraft in compatibility mode for windows 7
- Changing the regedit (Setting TdrDelay to 8, setting TdrLevel to 0)
- Disabling Windows Defender in regedit (DisableAntiSpyware = 0)
- Running Minecraft from its original file location and running it as an administrator
- Used DDU to uninstall the graphics driver, and then reinstalling the driver manually (Windows Automatic Update turned off)
- Reinstalled Windows 10
- Checked GPU temps to be around 30 C.
Interestingly, whenever I reinstall the graphics driver, Minecraft doesn't crash for a couple of hours, but then after that it will start crashing again.
Can someone give me other methods to try?
