    Bsod with dedicated GPU nvkflt.sys


    4 weeks ago I started to have blue screen problems, it would start with 1 per day but it increased exponentially. after reading up on it I downgraded the driver and the problems dissapeared for 2 weeks. I can run my laptop fine but when I start to do anything for which i need to use my dedi gpu (mostly Games) it crashes within 5-10 minutes.

    Here is what ive tried:

    1. completly remove all drivers in safemode and reinstall
    2. Checked temps, Yes it runs quite hot but the gpu doenst go over 73C before crashing.
    3. Clean the dust out of the vents.
    4. Complete virus Scan.
    5. Complete wipe of the hard drive and a reinstall of windows
    6. Sfc /Scannow

    Ive looked my fair share on google and have seen allot of problems with this error msg sadly I have not seen a fix. I am no longer within warranty so just sending it back is not an option.

    Service tag: 1QQ5GV1

    thanks in advance for even reading this

    There are no dump files in your logs to analyse, can you run the tool again and upload new logs.
