Windows 10: Error code c0000005 - Not a BSOD

Yea, I assumed it was the driver for my PS4 controller. I uninstalled it, and started Driver Verifier again, and everything is working fine so far (besides GTA V still spitting out appcrash error c0000005 every time I exit). In the meantime, i'll try to find a more up to date driver for my PS4 controller.

 

I don't think there is one available. This is the 3rd or 4th BSOD problem I've looked at in the last month or so that had a problem with ScpVbus and I don't remember any of them finding updated drivers. I hope I'm wrong, but ...

 

I actually found this (nefarius/ScpToolkit). Newer driver too (I believe March 27, 2016 or so?), though launching the driver itself with DS4Windows is a bad idea. Other than that, it seems stable so far, even with it running through Driver Verifier.

 

Seems a few different programs crashed on linux too (segfaulted). I'm gonna try to run Memtest86 again and see if I catch something this time.

 

Make sure you run memtest86+, not memtest86.

 

Any particular reason why Memtest86+ with DDR4 memory?

 

memtest86+ is what we always recommend. Did some searching and found this: Memtest86+ does not appear to be actively maintained, but Memtest86 seems to have been monetized. Which would you use - Memtest86+ or Memtest86... and why? : techsupport

I don't know how accurate this is but if true then we should be recommending the free version of memtest86, not +. I'll see what I can find out.

For now, stay with memtest86.

 

Ran memtest86 and found no errors.
Ran prime95 and found no errors.

Should I assume that the motherboard, or some other hardware is faulty?

Edit: Can a faulty motherboard corrupt the instruction pointer? The last appcrash I received did not have a corrupted instruction pointer, but was still memory corruption. Can a faulty motherboard corrupt memory then, or is there something else I should look closely at?
Problem seems to be getting worse now, though I'm surprised no BSOD's have shown up.

 

Yes, the motherboard can cause almost any kind of error, including memory corruption. Defective memory ports on the board have been encountered before.

Try removing 1/2 of your RAM, leaving 8GB. Run that way for awhile and see what happens. If okay it's possible the removed RAM is defective. Sw2ap removed and installed RAM and test some more. See if you can narrow things down this way.

Following shows where the single module should be installed.

I tried two sticks of RAM, in A1/B1, and still got error c0000005. Took them out, placed the other two in, same error. However, upon accidental restart, I received Q-Code error 55: Memory not installed. I haven't touched them, and they are correctly in the motherboard.

If it helps diagnosis somehow, I did have a problem turning on the computer two weeks ago, trying to figure out another problem. I couldn't even boot the computer until I hit the Clear CMOS button.

 

Two modules should go in A2 and B2 according to the diagram above.

Single stick in A2, two in A2 and B2.

 

Did the same for A2/B2, still got errors, minus the Q-Code error

 

Try just A2. If fail, try same module in B2, ven though it's not the recommended slot. Trying to see if you have a bad A2 memory slot on the main board.

 

They both still produced errors unfortunately.

 

Where do you stand as far as ScpVbus.sys and removing or updating the controller driver?
