ERROR_CODE: (NTSTATUS) 0xc0000094 - Screen no longer receives signal

Uninstall Daemon Tools, it's known to cause BSoDs. Update your graphic card drivers to their latest but uninstall older ones first. Also avoid "CCC" during installation. Watch the cards temperature cause signal cut off and black screens sound like a overheating card. If your motherboard has an onboard VGA slot connect there and see if you're having these issues.

SYSTEM_THREAD_EXCEPTION_NOT_HANDLED_M (1000007e)
This is a very common bugcheck.  Usually the exception address pinpoints
the driver/function that caused the problem.  Always note this address
as well as the link date of the driver/image that contains this address.
Some common problems are exception code 0x80000003.  This means a hard
coded breakpoint or assertion was hit, but this system was booted
/NODEBUG.  This is not supposed to happen as developers should never have
hardcoded breakpoints in retail code, but ...
If this happens, make sure a debugger gets connected, and the
system is booted /DEBUG.  This will let us see why this breakpoint is
happening.
Arguments:
Arg1: ffffffffc0000094, The exception code that was not handled
Arg2: fffff880072fc7a2, The address that the exception occurred at
Arg3: fffff88002176ed8, Exception Record Address
Arg4: fffff88002176730, Context Record Address

The dump of 22nd says you don't have the latest drivers installed for your card. What are the temps with Speccy?

Hmm. Isn't 73C° a little too much? When did you get this graphics card?
