"application has been blocked from accessing graphics hardware"

I've had this problem a couple of times with my laptop running windows 10. I'm docking my laptop to a docking station, which is connected to a secondary monitor. If I try to run any games with the HDMI cable connected via the docking station I get this error. For me the solution was as simple as just connecting the cable directly in to my laptop instead of going through the docking station (USB connection  to the laptop). I guess trying different cables/ports or monitors is worth a try if you're struggling with this issue.

Theoretically new machines are all setup off a disk that has everything for that machine, they are mass produced along with the machines, or now loaded through a network connection to HD. So more than likely you had a hardware issue, minor, but more than likely.

I also bought a Dell Inspiron 15 5000 laptop from Costco with AMD and Intel graphics on Windows 10 Operating System. I am not a gamer, but I was getting the "application has been blocked from accessing the graphics....." error whenever I used IE 11. To resolve the issue I went into Tools/Internet Options/Advanced and put a checkmark in "Use software rendering instead of GPU rendering".  The Switchable Graphics settings for iexplore.exe and chrome.exe are locked down to "Power Saving" mode by AMD and Windows 10 so this was the only way I could resolve the issue. Unless there is a way to unlock the "Power Saving" mode on the graphics card, I have a feeling you'll have to tell whatever software (gaming or otherwise) to use software rendering instead of GPU rendering to use these browsers. For gamers you may be able to add your application to the Switchable Graphics Settings and then select "High Performance" as the setting.

Hope this helps or lead someone to a better solution.

Justin, Since the laptop was only a week old and came with Windows 10 preinstalled, I took it back to Costco and got another. Two days and no problems yet.
