Multiple Bluescreens (DPC_WATCHDOG, VIDEO_TDR) after upgrade

FYI, the VIDEO_TDR_FAILURE means that the drivers weren't responding anymore and windows tries to get them working again. But the timeout is getting too much so the bugcheck is called to prevent any damage that may occur due to this problem.

Cause is the Nvidia Video driver.

Code:

2: kd> lmvm nvlddmkm
start             end                 module name
fffff801`d3fa0000 fffff801`d4a93000   nvlddmkm T (no symbols)

It might be due to some things that have to do with the memory.

Please download and install Speccy.
When you have installed and opened Speccy, click on RAM and click SPD -> Slot #1 (every slot) -> Timing table, please make a screenshot of it and post it
It looks like

Please try the following:

• Shut down your computer
• Once the computer is turned off, unplug all power sources (AC Adapter then Battery)
• Hold down the power button for 30 seconds
• Plug power sources back in (Battery then AC Adapter)
• Turn your computer back on

This will reset your software connections between the BIOS and hardware, and it will also clear any memory corruption in the temporary memory (disregard the battery statements if you are using a desktop and not a laptop).

Please try MemTest86+ again when you've done this.

Good,
Looks really like driver problems
