Hey anthony lobo. If you see hp logo have same problem during bios post then i am sure you need to reball or replace North Bridge. but make sure every track of pair of lvds signals from lvds connector to North bridge is ok. If hp logo seems ok then it might be Graphics driver problem. I hope it would help you to diagnose it. Thanks.
