Yesterday one of my office computers was forced to update to Windows 8.1. The update took forever and once it was done it decided to take out the driver for my graphic card (GT 620), I use two monitor and I could use one only now. I have updated the drivers through Nvidia site but after it asked me to re-boot the driver did not seem to take and was still missing. I tried several option, clean install, driver only, uninstall re install,... Now the computer will not even boot properly. I turn it on, it sows the Dell logo with the spinning wheel for few seconds and it goes straight to purple screen. There should be an option for me to log in at the purple screen, but I do not get that or any other option or button. I tries F8 and Shift+F8 to get to safe mode, but I cannot even to that. I do however get an option for F12 Advanced Options, but I did not find anything there to help. I can also get to BIOS but that is useless at this time. I am creating recovery driver from one of the other computers hat has successfully updated to Win 8.1 and see if I can get that operational, so far it is taking longer that the update. Meanwhile I would like to see if there are any other options out there. Thoughts?
