    BSOD nvlddmkm.sys VIDEO_TDR_ERROR nVidia GT 745A

    Hi there,

    I own a Lenovo IdeaCentre A730 All in One and it has an nVidia GT745A 2GB discrete graphics card installed along with Intel HD 4600 proc graphics. I bought this rig used and I think this was the main reason it was sold originally. I had a lot of BSOD I noticed whenever I watch a downloaded clip a minute or two into it the system would freeze for 5 minutes or more and go to BSOD usually VIDEO_TDR_ERROR nvlddmkm.sys which I researched is from my nVidia Card. I tried literally everything, Deleting and reinstalling the graphics card, tried pretty much most of the drivers from the Nvidia's website and clean Install option every time, tried to disable NVIDIA Virtual Audio Device and even tried installing a basic part of the driver package without 3D and Physics options, alas all my attempts failed! Interestingly, it's happening under Windows 8.1 Pro x64 as well ( I'm dual booting). The first attachment of the report is from Win 10 Anniversary Edition, now I'm on Creators Edition. I'm also attaching a screenshot of the Device Manager - this happens after a few BSODs Code 43. I saw lots of people have the same problem with so many different graphic chips. I also removed the CPU and GPU heatsinks and cleaned them out and reapplied thermal paste. The only way the PC works well is when I disable my nVidia Card! Please help!Attachment 131040Attachment 131041

    Since this is a common error "code 43" with this GT 745A, the cause could be a hardware failure. This is the result from my bsod analysis:
    0x00000133:    DPC_WATCHDOG_VIOLATION (30.03.2017 07:58:37) [Windows 10] 
    CAUSED BY:     nvlddmkm.sys [16.03.2017] * nVidia Video drivers * => http://www.nvidia.com/Download/index.aspx  
                   hal.dll  (Hardware Abstraction Layer DLL. NO Driver)  
    PROCESS:       System

    Since u tried many things like reinstalling GPU drivers u can try updating your BIOS if there is a newer one:

    BIOS_DATE: 04/11/2013

    U can try to disable the INTEL onboard GPU and see what happens
