System shuts down when in sleep mode

I really am not sure where to even look. I upgraded from 8.1 to 10 and had no problems for a while until I began using sleep mode. About every night or two when in sleep mode, my system shuts down. I'm not here when it does so I don't see a blue screen and appear to have no other problems.
I used WhoCrashed and get this info every single time I check it.

crash dump file: C:\WINDOWS\Minidump\100815-12343-01.dmp
uptime: 14:28:45
This was probably caused by the following module: ntkrnlmp.exe (nt!KeBugCheckEx+0x0)
Bugcheck code: 0x9F (0x3, 0xFFFFE001FD59D710, 0xFFFFD001F6446990, 0xFFFFE002062B69E0)
Error: DRIVER_POWER_STATE_FAILURE
Bug check description: This bug check indicates that the driver is in an inconsistent or invalid power state.
This appears to be a typical software driver bug and is not likely to be caused by a hardware problem.
The crash took place in the Windows kernel. Possibly this problem is caused by another driver that cannot be identified at this time.

I can build computers but I suck at figuring out problems like this. All the drivers are up to date and since this started, Nvidia has had 3 driver updates that I've tried that make no difference.
Can someone point me in some direction to try and solve this problem?

Thanks

No, things were working so well I decided not to do a clean install. In the past, I've always done that but thought I hit it lucky. If this can't be fixed, I guess that's what I'll do.
In the meantime, here's a link to my MSInfo and dump files if anyone is interested in looking at them.
