Crash dump directory: C:\Windows\Minidump Crash dumps are enabled on your computer. On Sat 30/07/2016 12:07:09 PM GMT your computer crashed crash dump file: C:\Windows\Minidump\073016-306401-01.dmp This was probably caused by the following module: ntoskrnl.exe (nt+0x32D9E7) Bugcheck code: 0x124 (0x0, 0xFFFFFFFF8CBDC8FC, 0x0, 0x0) Error: WHEA_UNCORRECTABLE_ERROR file path: C:\Windows\system32\ntoskrnl.exe product: Microsoft® Windows® Operating System company: Microsoft Corporation description: NT Kernel & System Bug check description: This bug check indicates that a fatal hardware error has occurred. This bug check uses the error data that is provided by the Windows Hardware Error Architecture (WHEA). This is likely to be caused by a hardware problem problem. This problem might also be caused because of overheating (thermal issue). The crash took place in the Windows kernel. Possibly this problem is caused by another driver that cannot be identified at this time.

On Sat 30/07/2016 3:31:44 AM GMT your computer crashed crash dump file: C:\Windows\Minidump\072916-58266-01.dmp This was probably caused by the following module: hcwpp2.sys (hcwPP2+0x7DA8) Bugcheck code: 0xC4 (0xF6, 0x16A8, 0xFFFFFFFFE26443F0, 0xFFFFFFFF94EB1DA8) Error: DRIVER_VERIFIER_DETECTED_VIOLATION file path: C:\Windows\system32\drivers\hcwpp2.sys product: WinTV company: Hauppauge Computer Works, Inc. description: WinTV PVR PCI II (v2) WDM Video Capture Bug check description: This is the general bug check code for fatal errors found by Driver Verifier. A driver references a user-mode handle as kernel mode. This appears to be a typical software driver bug and is not likely to be caused by a hardware problem. A third party driver was identified as the probable root cause of this system error. It is suggested you look for an update for the following driver: hcwpp2.sys (WinTV PVR PCI II (v2) WDM Video Capture, Hauppauge Computer Works, Inc.). Google query: Hauppauge Computer Works, Inc. DRIVER_VERIFIER_DETECTED_VIOLATION

On Sat 30/07/2016 3:31:44 AM GMT your computer crashed crash dump file: C:\Windows\memory.dmp This was probably caused by the following module: hcwpp2.sys (hcwPP2+0x7DA8) Bugcheck code: 0xC4 (0xF6, 0x16A8, 0xFFFFFFFFE26443F0, 0xFFFFFFFF94EB1DA8) Error: DRIVER_VERIFIER_DETECTED_VIOLATION file path: C:\Windows\system32\drivers\hcwpp2.sys product: WinTV company: Hauppauge Computer Works, Inc. description: WinTV PVR PCI II (v2) WDM Video Capture Bug check description: This is the general bug check code for fatal errors found by Driver Verifier.

Conclusion

---

8 crash dumps have been found and analyzed. 2 third party drivers have been identified to be causing system crashes on your computer. It is strongly suggested that you check for updates for these drivers on their company websites. Click on the links below to search with Google for updates for these drivers:
hcwpp2.sys (WinTV PVR PCI II (v2) WDM Video Capture, Hauppauge Computer Works, Inc.) hal.sys
If no updates for these drivers are available, try searching with Google on the names of these drivers in combination with the errors that have been reported for these drivers. Include the brand and model name of your computer as well in the query. This often yields interesting results from discussions on the web by users who have been experiencing similar problems.

On the plus side, it's much cooler today and the core temps are down - 54C to 56C at the moment.
 
Haven't seen a true BSoD crash yet, but I'm still getting the Display Driver crashes.
One thing that I get a lot of is the screen will go black and I get a message from the monitor saying it has gone into eco mode. This will last for anywhere from a few seconds to several minutes as the screen flashes and attempts to come back. Often it is showing various parts of what was on the screen originally, and sometimes it even displays something from a tab that I was looking at previous to the one I was looking at when it crashed.
 
 

Re: Testing the RAM
 
Good idea - I'll try and set it up tonight before I go to bed so it can run all night.

Looks like you're still getting the 124 bsod even at default voltage. I would say go higher but your temps may become a problem. You should try testing your cpu with the intel processor diagnostic tool to see if your processor can pass it or not. Remove WinTV to get rid of the the other blue screen errors.

 
Just ran the Intel Processor Test - Here are some of the results (I left out about half the report as it is quite long and redundant):
Bottom line is that the CPU passed all tests except one

Haven't had time to pull RAM and test them individually, but did test all of it.
Passed all tests.
 
I'm beginning to wonder if the problem might be in the motherboard...

UPDATE:  Ran MemTest again last night for almost 8 hours. Passed with no errors.
 

I'm thinking you still need to raise the vcore more. You should try testing the cpu in another computer if you know anyone that has a lga 775 motherboard.
