intermittent BSOD and Program crashes and GPU related on P07-650 Riser Cable

I've been having intermittent BSOD issues and in general programs crashing. A lot of the issues seem GPU adjacent. Strange things like I can't update the driver unless it is the first thing I do after restarting the computer. I don't have actual GPU issues like black screens or fuzzy displays, the occasional fuzzy videos I guess.

I'm wondering if anyone has had issues with the riser cable that attaches the GPU to the motherboard. These issues happened after having the computer for 6 months and fresh installs of windows or changing drivers have no impact on the issues. Seems kind of like a low possibility but maybe the cable has vibrated loose or a bend in the cable has gotten worse but I'm not sure if what I'm suspecting is even possible.

Could the riser cable be my issue?

The gpu riser cable will only affect the image or functionality of the gpu if its damaged or not plugged in properly into the mainboard or gpu or its plug is fried (which was an issue with the Nvidia RTX30xx gpu’s as they sucked allot of power and their plugs were of inferior quality) which you should not have as the PO7-650 has the GeForce RTX™ 4080 series gpu’s which this is not an issue with, as its very rare that this cable contributes to the faults that you are having, also try to replace the cable and see if you think it’s the cable.

I would start by updating the bios of your PO7-650 desktop to the last version R01-A3 titled “Add DMI information judgment conditions” and also update the Firmware to version V003 titles “Type C PDFW_V003” that the PO7-650 desktop and also make sure that all windows updates are up to date and that all windows firmware updates are also installed for this desktop in Windows Update > Advanced options > Optional updates > Driver updates > Insyde Software - Firmware or something like that and see if all these updates will solves the issues that you are having. Good luck and hope this helps you out.

Also, take pictures for us of some of the BSOD screens. We can often get some insight into what's going on from them.

I zipped the minidump files I've been saving and made them available at this link.

So it looks like the issue is in the calls to bcryptPrimitives.dll, which is typically done when encryption is used for something. In your case it's a Windows service calling it. Boot in safe mode to test to see if you can still get the issue to show. If so we're looking at a Windows caused event and likely require some more diagnosis to clear up whatever is corrupted. If you can cause it to happen in safe mode, then it's more likely a third party app. Use msconfig32 to disable third party services, then re-enable them until you can cause it again. That should help pin it down…
