Hope you all doing well, i have a Dell Precision M6400 mobile workstation, with a Nvidia Quadro FX 2700M dedicated card. I am running this on a non-genuine but branded charger of around 110W which is enough for normal use without battery. The issue i am getting is while benchmarking or trying to use graphic related thing which will use gpu power or sometimes normal usage, my display shows little green lines for around 1 mili second (very little time faster then the eye blink) i think so, and shows black screen, system is running but screen turns off. what could be the issue? the temperatures are/were alright not exceeding 50 degree. If gpu is failing i know it will require replacement but in this time i won't be able to find 1 gpu compatible of my machine, there are several issues, major one is my city is not advanced enough. What could be the alternate to keep using this machine? i can't afford a new or better one.
