"application has been blocked from accessing graphics hardware"

I added another stick of RAM about 2 months ago and haven't had the problem since. I'm not saying that the two things are directly related...all I'm saying is I haven't seen it happen since I put the additional RAM in.

Might be worth a try...

I've already looked at the memory question, I'm using about 7% of the total memory available on my machine.  That was one of the first things I looked into  since it's so easy to check.  In fact, that was the reason I replaced my old laptop, it didn't have the memory needed to run my key software for work, Logos.

To me it is a cheap thing to try, swap out your RAM, if you have low RAM swap out to a larger amount also.

      I had this problem since Windows 7, I did memory test all seemed good. Windows XP ran fine, Linux OS,s ran fine.

I swapped every piece of hardware, I built another machine from the parts i had pulled from this machine added memory and all was good.

     That is when I knew it was the RAM.  I put the old RAM back in bingo ERROR back again. new ram, bingo ERROR gone.  

     ****, to me if it is the issue, it a cheap easy swap. get on Newegg order some inexpensive motherboard approved Gskill ram and see if it works.    I am betting it does for most.

      I have heard it too many times over the past 6 years, since this appeared, of memory swap being a fix. 

   If you have done everything else give it a try.

{{{let us know how it goes though. }}}

Microsoft has messaged me about please giving them any info I find on this subject, and I think it is memory related.

Thanks for your feedback. However, if it was a RAM problem wouldn't have I had this problem from the start? I run music software that is very memory heavy and experience no problems at all. Last night I tried to adjust my screen dimmer - computer crashed and rebooted. I definitely think it is some kind of graphics-OS compatibility issue. 

It seems some people have found fixes but they only seem to work for the person who found the fix and/or only a couple of others who coincidentally had the same issue.

I got this reply from my own post, but it is a bit too technical for me. Can anyone make use of this information?

If you completely removed the nvidia driver and OpenGL and some of the hardware tests are failing I am suspecting hware.

Event viewer is showing quite a few nvidia/opengl errors and many others

The computer has rebooted from a bugcheck.  The bugcheck was: 0x00000116  This bugcheck is most often related to HEAT

These crashes were called BCC116 and are related to your video sub system.  Please follow the instructions in this wiki

The description for Event ID 1 from source NVIDIA OpenGL Driver cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.

Display driver nvlddmkm stopped responding and has successfully recovered.

Session "ReadyBoot" stopped due to the following error: 0xC0000188

Activation context generation failed for "D:\Music\Guitar Pro 6\GPInstaller.exe". Dependent Assem"

From what I can tell that bug is related to video hw/sw .

     You can download CPUZ GPUZ to keep track of temps while you run your software.

When removing and reinstalling graphics drivers they dont always remove everything, I usually use Driver Sweeper after the manufacturers (Nvidia/AMD)removal tool.

Event 1 just states the NVIDIA opengl driver crashed or didn't start or isn't there to run.

Ready Boot error is nothing to worry about from what I gather, system runs fine, ready Boot is a function of ReadyBoost that speeds up boot times.

From what I can find the GPInstaller error seems to be either corrupt or missing from that software installation, try reinstalling that software, also possible missing/corrupt compatible C++ Redistributable version.

Yes, my system had noticeable issues from the start, however it did not throw up errors until later, why I have no idea, so I wouldn't be so quick to disregard this possibility.

I had dealt with this for 6 years, and this was my fix.
