Application has been blocked from accessing graphics hardware. PLEASE help

[kingweezel]

I built my computer a few years ago and recently ive been having a lot of problems with my computer crashing/ freezing. I have 16 gigs of ram, water-cooled 980, and a water-cooled 6600k. Over the past few months ive been getting crashes in games and it says "Application (some game) has been blocked from accessing graphics". Yesterday I thought it would help to clean up my computer and do a fresh install of windows. I used asus secure erase to wipe both of my ssds (samsung pro 128gn and 500gb). I updated windows, my drivers, installed steam, discord, asus gpu tweak, and icue. I was looking forward to playing bl2 but soon realized my computer still has a crashing issue. Today ive crashed at least 50 times in a 5 hour gaming session. It started off with my primary monitor going black, followed by my second then they would both reappear and sometimes I would be able to get bl2 to reopen but sometimes i needed to force close it or even restart my pc. After happening about 8 times my computer started to block applications from accessing graphics hardware. It started off slowly with bl2 being blocked about twice an hour. In the last hour the problem has progressed immensely! I crashed about 30 times in the last hour and every time my whole computer freezes and doesn't allow me to do anything but i can still hear the game audio and discord(I can still talk to my friends sometimes but everything would be frozen). My computer has went from blocking just the game to everything on my pc it seems like. Ive spent around 30 hours in the last 3 months trying to fix the issue with no luck. Any help is greatly appreciated.

Have you tried reinstalling Windows? It's a good step.

not sure if this is the case, 

you need to manual install directx / visual c++ (all versions  x64 & x86 all way back to 2012...)

I reinstalled windows on my wiped ssds and it seemed to of made the problem worse as my computer is not not allowing Microsoft windows to access graphics hardware as well as most other applications on my pc

Here's a registry entry for a fix I found online. It might work.
A file is attached in this comment below.

1. Download the .reg file.
2. Opening the file gives you a prompt. Click Yes on subsequent dialogs and Click OK in the last dialog.
3. Restart your system.
