Hello all and thank you for your time.

I have a Precision 5520, Intel i7-7820HQ with NVIDIA Quadro M1200 and Intel HD Graphics 630. Bought in 2017, it served me well, I replaced the battery once and overall I am happy with it. However, recently I've been getting VIDEO DXGKRNL fatal errors more and more frequently. It began by crashing while rendering in Adobe After Effects or while using more than one application at the time (which obviously wasn't a problem before) and now it crashes even when using simply google chrome. 

I contacted Microsoft support and they haven't been able to assist apart from telling me to reinstall my graphics card drivers which I did, to no success. Moreover I tried google search and applied any and all solutions I found, with no solution fixing the problem. A diagnostic of the PC shows everything is healthy.

I've seen a post about this error here back in 2014 but I believe things have changed since then. I like my Dell and I would love to continue using it but it has become simply unbearable to work. I am out of options, any help will be appreciated.

Thanks
