Hi I upgraded my CPU to an i7 from an i3 and there is no display. I removed the cpu and put it back in still no display. I then put my i3 back in and tried updating to the modern bios but my pc won't load the prompt to update it. I use a Dell G5 5000 prebuilt and used the dell support page to download the files for it. When I downloaded the file and ran it it gave me the response of allow to make changes. When I clicked run it is supposed to restart but nothing has happened since. I even tried redoing it at least ten times but still no restart or system bios prompt that supposed to show up. Am I doing the right thing in trying to update my bios or is there a different alternative?
