Great, thanks for the reply, did a fresh windows installation and prior to this I downloaded the latest intel graphics driver from intel website and also the latest Nvidia graphics driver from intel website because I realized the versions in dell website were older versions and I suspected the old drivers were the ones responsible for the video tdr failure and this watchdog violation, so after OS installed, I disabled windows update permanently via the policy editor and the registry, then installed the intel driver first and then the Nvidia and restarted pc, then I installed the revit and AutoCAD software and tried testing the pc by doing some heavy settings rendering in revit that lasted about two hours and the pc never ran into the video tdr failure and so on, previously it couldn't do this for even 5 minutes before running into blue screen, my question now is , being that I've only installed the two graphics drivers and no other drivers since I'm afraid I'll only find old ones that makes pc run into blue screen, will my pc just run normally with only these two graphics drivers and not others, last time I installed OS and let windows run update to install drivers and when I installed revit and tried those renderings, it ran into blue screen quite often, for now the pc really works well with just the two graphics drivers but I know there are other drivers that it will have to need, I'm even afraid of installing or turning on framework 3.0 and 3.5 that needs to be downloaded and installed from windows update, what can I do over this dilemma, I'm trying by all means not to run into these blue screens by being choosy on what drivers I install
