If you got the driver from Intel, that was a mistake. Dell customizes the Intel driver (as well as all other drivers)for your exact model. Get the right driver from Dell Downloads and Drivers. [URL] I assume you reinstalled Windows when you got it from the company. You cannot get the computer to do anything without Windows. If you have not done that--Burn the files for windows 10 reinstallation to disk or thumb drive by using the Create Media Tool
Hi everyone,  I recently lost my job due to the company I worked for shutting down because of covid, so they wiped our laptops and then sent them back to us to keep. Unfortunately whoever wiped my laptop has done something as my laptop no longer works.  Issue: Whenever I try to login it either freezes when inputting my password, or shortly after the desktop loads. It blue screens with an error message "stop code: whea uncorrectable error" I can however use my laptop as normal, BUT only if I boot it when it is plugged into my second screen. As soon as I unplug the second screen however it instantly freezes and blue screens. Same if I try booting without the second screen connected.  This got me thinking it was something to do with the graphics driver, so I tried updating/reinstalling different versions of the Intel UHD Graphics 620 etc. But was still having the same issue with freezing. I then tried to rollback the driver to the Microsoft Basic Adapter, and this worked- when it is set to this display adapter it works as it should. Obviously the basic adapter lacks the ability to have multple screens which is an issue so ideally I want to get the intel driver working again.  Has anyone else had this issue? or knows if there is any fix here that allows me to get the intel driver working properly? Or maybe these issues are just a symptom of a larger/different issue that i'm missing? Any help would be very much appreciated! FYI the model is: Dell Latitude 7490
