|My Computer Won't Boot... I didnt delete any Drivers or change any settings, I simply swapped Cards. Now either card doesnt work..|
New card: XFX Radeon HD 5570
Old card: XFX Geforce 7900 GT
I'm struggling to Troubleshoot by eliminating options because nothing works.
New Card + Vga Cable + Monitor = "HP Dos Screen with: F1 for Setup, Etc" then "Black Screen"
New Card + Vga Cable + Tv = Nothing.
New Card + Hdmi + Tv = Nothing.
New Card + PCI-Cable (the wider slot.?) + Monitor = Nothing
New Card + PCI-Cable + Tv = Nothing
Old Card + PCI-Cable + Monitor = Hp Dos Screen, then black screen with an UNDERSCORE "_" top left
Old Card + Vga Cable + Tv = Nothing
Old Card + PCI-Cable + Tv = Nothing
Old Card + Vga Cable + Monitor = Hp Dos Screen, Black screen with Underscore.
Could I have messed up my Pc because I switched from NVIDIA to ATI without removing drivers first?
