I was given a dell studio cos 9000 and it wont output any video to my monitor. My uncle said to put the original gpu in because it might be a pci card but i looked up the specs and it the site i looked at said it had a pci e gpu in it. I dont have a pci card to try so any help would be greatly appreciated. The motherboard is not blinking and when i turn it on the fans and stuff start moving but there is nothing shpwing up on my monitor. Its not my gpu because I use the same one in ny other PC.
