"application has been blocked from accessing graphics hardware"

I'm fairly certain this is a hardware/driver issue.

As I've said earlier in this thread, I was able to eliminate the error by changing browser settings to use "software rendering" instead of "GPU rendering". This is not a solution, but a workaround.

I have had some success by using the Intel graphics utility and set it to "performance."

recently every time i use a program that use my gpu( I have optimus technology so it switch when needed etc...) I get the error message " application has been blocked from accessing graphics hardware", the internet does not seem to be very helpful about this problem, does anybody know what causes it/how i can fix it ????

thanks for any help,

Recently upgraded to Win10Pro. Even with NVIDIA drivers for my graphics card updated, kept getting "black outs" with errors saying "nnnnn application has been blocked...."

After trying multiple suggestions from my google-ings, I came across one that seems to have worked.

What seems to be happening is in the Intel driver MS uses as the default driver. For whatever reason, it has issues. 

What the link above does is it walks you through downloading a beta driver from Intel and replacing the MS version.

Naturally, make a system restore point before hand, just in case.

All I can say, it seems to have worked. Halleluyah.

Just thought I'd pay it forward.

Unfortunately, I've not found any information on a driver fix outside of the MS Intel driver workaround above. If you have a graphics card that isn't Intel, you're up a creek.

If somebody discovers something, let me know!

My system was STABLE for many years but since I recently performed a format and a system reinstall, errors started popping.

This make me believe that it might be a software error and specifically related to newer updates in Windows 10.

I've noticed that if I try some set of fixes I got: 'Driver stop responding' error, and if I try another set of fixes I get: 'Application blocked' error instead.

Tried so far:

• Clear CMOS (Did nothing)
• Flash and Update BIOS (Did nothing but it was good anyways)
• Clean MB/GPU/CPU (Lowers Temps)
• Play with TdrLevel (3 is more stable than 8)
• Wipe Graphic Drivers in safe mode 
• Use Microsoft video drivers instead (Less stable)
• Use AMD's latest video drivers (More stable)
• Disable Firewall (More stable)
• Change GPU PCIE Slot (More stable)
• Downclock GPU (Did nothing)
• Downclock CPU (More stable)
• Disable windows page file (Decrease occurrence of errors)

Will try:

• Use HDMI instead of Mini-DisplayPort (System was stable for long years using HDMI)
• Test Memory Sticks
• Reinstall System
