Unexpected Error. Cause: Processor drops to 0%

As the title says, I found what could be the cause of the Unexpected Error in my case. Still, after doing a bunch of research, I have yet to find the cause of this issue. Anyone got any ideas? Here's my specs currently:

I can post the full DxDiag thing if needed

Hi peeps just wanted to say I had been having the same issue for EVER. I went into regedit and gave it a Tdrdelay of 8 (DWORD) not (QWORD) I have been playing for 3 days now and so far I have had no crash running on a Gforce 750ti . I tried this once before giving it a delay of 4 and it didn't work so I abandoned the idea suffering. On a whim I dug more and found a fix with the Tdrdelay. I also set my Nvidia 3D settings to advanced 3D imaging as another fix for my card. The regedit path I modified was: open regedit, HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Control/GraphicsDriver, right click mouse over "new" click DWORD rename TdrDelay modify 8. WARNING!! Do not use this fix if you are not comfortable using regedit you can really mess up your PC ( I see this written each time Iv'e seen this fix so I feel it necessary to add it as well) Hope it works, it did for me. Happy gaming.

It has now been over a week of playing with this fix and I have had no issues what so ever highest settings. It took me a yr of looking to find this fix fyi it drove me crazy LOL

That fix didn't work. (Also, why do you keep copy-pasting the same thing?)

Ok, I did a different fix and so far, so good. Unparking the cpu. Those that wonder how it's done, here you go (It uses the regedit too so be careful)

Copy the following registry key entry between the brackets [ 0cc5b647-c1df-4637-891a-dec35c318583 ].
Select your start button.
On the search bar type in “regedit”.
Go to edit->find->find next.
Paste this registry key but without quotes “0cc5b647-c1df-4637-891a-dec35c318583” and click find.
Once it has located it, look for the keys on the right hand side labeled MinValue and MaxValue.
Double click on each value and make sure they are both set to ‘0’.
Close the registry editor and shut down your computer.
Power the computer back up.
Core Parking should now be disabled.

eDIT: Scratch that, it popped up again after 3 hours
