Default GPU Messing up Monitor?

Hey all, my friend called me with a computer problem this morning, and I think I diagnosed the problem okay. Still, it be nice to have those smarter than me give their opinion. So, whenever the computer turned on there would be many vivid, vertical lines clogging the screen. It was impossible to see anything clearly, but some things could still be made out (like the loading bar, so the OS was still booting up right. Screens while actually booting up weren't as obscured as the Windows ones). I brought in a different monitor (that used a DVI connection instead of his HDMI as well), and the problem persisted. After a thorough dusting and no results, I said it was a video card problem. Also, the menu that comes up for adjusting monitor settings was clear if that means anything, but I just took that as meaning that it's not a monitor issue. Another note: the computer was really dusty, and the house was hot, so maybe the GPU was damaged by heat.

His computer is an HP media center. Can't remember the exact model but it had:
AMD Phenom Quad, whichever one is clocked at 2.2 GHz
640 GB HDD
Nvidia 8400 256MB

Thanks in advance for any help.

gpu issue, try and rma through hp as that's a rather new computer. hopefully it's still under the 1 year warrenty.

A notice to EVERYONE who has posted here with a computer problem, I highly encourage you to keep current with the forums, even if it's browsing for 10-15 minutes during lunch, or before you go to bed at night. There are many things that you can learn and apply to future issues. My goal is to help people get to a point where they can use their own knowledge to help themselves, and others.

Also please use the search button. You've got a 50/50 chance that someone's asked your question and we've answered it.

The motherboard wouldn't happen to have "onboard" video also would it? If so try it.

If not. Obviously trying another videocard would be a good step.

IMO there is a GPU issue. Is there any thing else he can hook up to the screen using them ports just to rule something in the screen out?

Can't. Impossible to navigate after getting to the Windoze desktop. Thanks for the help everyone; I'll be back if a replacement GPU doesn't work.
