Constant Crashes/BSOD with different error messages.

As per the zip you uploaded, the latest BSOD is of 08.06; which is a stop 0xA, and already checked earlier.

If you get a stop 0x1, I would suggest you to enable Driver Verifier to monitor the drivers.
Driver Verifier - Enable and Disable
Run Driver Verifier for 24 hours or the occurrence of the next crash, whichever is earlier.

   Information

Why Driver Verifier:
It puts a stress on the drivers, ans so it makes the unstable drivers crash. Hopefully the driver that crashes is recorded in the memory dump.

How Can we know that DV is enabled:
It will make the system bit of slow, laggy.

   Warning

Before enabling DV, make it sure that you have earlier System restore points made in your computer. You can check it easily by using CCleaner looking at Tools > System Restore.

If there is no points, make a System Restore Point manually before enabling DV.

   Tip

• If you fail to get on the Desktop because of DV, Boot into Advanced Boot Options > Safe mode. Disable DV there. Now boot normally again, and try following the instruction of enabling DV again.
• If you cannot boot in Safe mode too, do a System Restore to a point you made earlier.

Let us know the results, with the subsequent crash dumps, if any. Post it following the Blue Screen of Death (BSOD) Posting Instructions.

Boot into Safe mode. Disable DV. Boot into normal mode again .... (it will do) and enable DV again. Make it sure that you are not selecting any driver supplied by "microsoft" or "unknown" and run the computer with DV on ... hopefully it will go to desktop before crashing again.

The bsod is caused by PxHlpa64.sys.

---------

You need to uninstall it. A list of programs that includes the driver is here: pxHelp20.sys programs .. I will add quicktime with that list.

Uninstall any program contains that driver.

Do to C:\Windows\System32\drivers and C:\Windows\Syswow64\drivers, and delete PxHlpa64.sys manually.

BTW, MagicISO and MagicDisc, with their fake SCSI controller is present there, still.

Let us wait and see :)
