Hello I was replacing my HP screen and once done the screen was not readable as the computer started up, but once the computer was done completely booting up, the screen was readable. At this point i was running vista. Then i decided to install windows 7 and since it was not readable when starting up i decided to plug in a monitor. Once it was completely installed and booted up the screen was not readable again .
(This is what it looks like http/imgur.com/fJbdsu5
is the screen defective or is there something wrong with my computer? Any suggestion helps
