Hello. I recently attempted to upgrade my GPU and have come across an issue after uninstalling all graphics drivers. When I start my pc it seems that everything powers up but I am not getting any display signal. I have tried to plugging straight into the on-board graphics and didn't get a signal there either. I'd also like to point out that I used a program to uninstall the graphics drivers and that the no display started happening after I took my CMOS battery out to reset. Thanks in advance for any advice!
