Fuzzy Display after Windows Update - HP Diagnostic does not proceed ahead after language selection

[Sidd168]

Hi this is Sidd here, after a recent Windows update I found my display all fuzzed up (refer to the picture). I have tried resetting the system, updating the driver using device manager etc. I have also tried rolling back the drivers but the issue was not resolved. I then decided to run the HP Hardware Diagnostic, which would not proceed after selection of Language. Please help, it has been 3 weeks now and I am stuck with a fuzzy display with no idea if it is a software issue or a hardware issue. The screen at times corrects itself with a clear display at the top of the screen (1/8th of the screen).
