I'm new to this forum. I have been desperately searching for help online and after looking through the posts, I thought someone here might be able to help. Background: Computer was in one of our storage units and left behind when they couldn't pay (not a good thing I know). It's a Compaq Presario SR2150NX, VISTA, no hardware added that wasn't factory from what I can tell. Problem(s): Number one is that Nothing on the screen at all. Just blank Problem Number 2, the CD-ROM opens on start up by itself. I don't know if these problems can be related but I'd love some help. The graphics card is the integrated type so I thought getting a new card might help. I added some memory, 2 GB total. I got an NVIDIA GeForce 9500 GT and physically installed it but nothing happened when I turned it on, still blank on the monitor and there's still that issue of the CD-ROM opening automatically when I turn the computer on. I tried putting a CD in and closing it, it lit up like it was trying to read it and then opened up again on it's own like it was spitting out something that tasted bad Is there anything else that could cause the monitor and computer to not communicate besides the graphics card? How can I install this new card/drivers when I can't see anything on the screen? I did a quick search in this forum and didn't find anything I thought would help. What size power source does this graphics card need? I think the one it has is 300w, can that be an issue? What am I missing?
