Use !analyze -v to get detailed debugging information.

BugCheck 3B, {c0000005, fffff80003088e5e, fffff8800a7a5ea0, 0}

Probably caused by : ntkrnlmp.exe ( nt!KiSignalSynchronizationObject+4e )

Followup: MachineOwner
the causes for the Bugcheck range from corrupt drivers or third party apps to possible hardware faults (usually RAM). I also noticed you had dump files with probable causes for graphics, Network and memory corruption.
Looking through your driver stack I see your drivers are of the latest versions and all looks good.

Try removing any third party apps just as a simple test to see if the bsod stops. For example I found this driver cropping up a lot:
ALSysIO64.sy : Core Temp - CPU temperature monitor or at least I think it is. Notice the 's' missing on the .sys. I wonder if this is down to corruption. Try removing and re-installing:

What are your system temps like?

Check for system corruption by running a system file check. Open an admin command prompt (right click on command prompt and click run as admin) and type:
sfc /scannow
Press enter and await results.

Please check the RAM on your GPU by running the test found here:

Can you post how long you tested the RAM for?
