System hangs Occasionally After Screen Blanks

About once a week or two when my system (System One in Computer specs) goes into S3 sleep, the screen blanks, but the system never powers down. I have At this point, the system appears dead, but the disk activity LED is blinking just like it's running normally. However, screen is blank, and keyboard and mouse are unresponsive. I have run a stress test with OCCT diagnostics for several hours, it didn't turn up anything.

When I check the event log, every time this particular hang happens, I always find Event 14, mvlddmkm. My looking around seems to indicate this is a Nvidia driver issue. I have uninstalled and updated and downgraded the video drivers, but no joy so far. Of course, this is hard to test and it only happens every week or two. It appears, since there is a two minute span between the error below and the restart, that the Event 14 is the last error logged before I pulled the plug and restarted.

this may help or at least give a hint.

is 'fast start up' disabled. if not please disable
do you have hibernation file enabled. if so please disable

and it also maybe worth while to do a chkdsk (check disk)
this will require a reboot for it to perform any repairs.

had to this for my wife's computer to get S3 working.
best of luck Steve ..

Actually, I've done all of this. I never had fast start up enabled, and I have also disabled hibernation some time ago. I just disconnected from my RTX 4060 and I'm running the displays on the Intel built-in graphics to see if that has an effect.

Well, I moved to the motherboard video ports and the problem has not repeated. So, it appears that it probably is the nVidia drivers for the RTX4060 are the likely problem. I'm going to give them a couple months and then download the latest drivers and try it again.
