Application blocked from accessing graphics hardware

Recommended Posts

Posted · Original PosterOP

Hello,  I've been having a bit of a frustrating issue recently where games will freeze up for 3-5 seconds, then recover. It is only the game that freezes, I can still move my mouse around and tab out when it happens. Initially began when playing WoW TBC and now with Diablo 3. GPU temp sits around 70-75c when this happens. 

 

My PC: 

i5-4460

8GB 

Sapphire R9-270X

Ennermax 525w (Pro 82+)

 

At first, the freezes gave the error notification of "application blocked from accessing graphics hardware". I've tried:

- fresh installing drivers (removing in safe mode with DDU)

- uninstalling drivers and letting Windows auto install

- adding TdrDelay to registry 

- underclocking GPU core / memory 

 

Yesterday I reinstalled Windows 10. Latest drivers installed. Same issue only now there is no error notification. Anyone have any ideas on what else to try or what could be the cause?

sounds like some tool/software running in the background is causing this. try deactivating your AV. If the freezes still occure then take everything out of your autostart, reboot and try again

 


My Setup: 
CPU: i7 4790 @3800 MHz, MB: MSI H87-G41, Grafik: Gigabyte GTX 1080TI, RAM: 2x 8GB DDR3 (1600), Storage: Samsung SSD 850 Evo

I'd probably try getting a new power supply. If it's the culprit, you should replace it ASAP.

Get a Corsair CX450, CX550, CX450M or CX550M. Very good PSUs


Ryzen 5 1500X 3.925GHz @ 1.24V with stock cooler, 1x8GB DDR4, GTX 950, Corsair 88R, 1TB HDD, 240GB SSD, Corsair 88R, Phanteks RGB LED Strip (400mm), planning on getting a 144hz monitor soon

1500X Cinebench score: 770cb

1500X Cinebench score (3.9GHz @ 1.24V) : 875cb

GTX 950 Cinebench score: 96.31fps

 

1500X idle temperature: 33C

1500X load temperature (1 minute sustained, non-AVX) : 55C 

1500X load temperature (OCCT AVX 64bit all cores/Prime95 1h sustained) : 65C

I kinda figured the same thing, but still happens after a fresh OS install with nothing but D3, Discord and Chrome installed. Could Windows Defender be messing with things? I just realized this started happening after a recent Windows Update.

Should not... Which Win10 Version do you have? 1809?
