Server video card problem affecting RDP video?

Hello fellow Experts,

One of the servers I support probably has a bad video card.  We are on a Belkin KVM with one of those fancy APC 1u keyboard monitor drawer things.  Everything else plugged in works fine, but that one server's video is totally scrambled, even during POST, so it isn't Windows or a driver that I can tell.  I haven't brought another monitor and cables down to verify it isn't the port or connection between the server and the display.

What I was wondering, is would a bad video card cause possible display issues when using terminal services to access the server?  In the past month or two, the logon window is blacked out when TSing into it.  See:  http://www.managed-data.com/termserv.jpg

FYI- around the time these problems started, we had a script running a temp backup procedure fill up the C: and the problem was worse, couldn't see anything until I VNCed in and cleaned off C, and rebooted.  The thing is, is a few weeks later, we discovered that the server had been running a little hot and had kicked some warnings and wasn't happy.  It even shut itself down once.  I assume this could cause some hardware problems, duh.  

Anyways, I went ahead and did some good fans to ventilate the cabinet, which they were supposed to do a long time ago.

The main question is, would video card hardware problems cause that blacked out stuff in RDP?  Any other thoughts?  I'm thinking I may call HP and see if the video is under warranty, but they will need to do a whole motherboard since it is 1u rack-mount with on-board video.

Thanks in advance!

Have you tried power cycling the KVM?

Bad video shouldn't affect RDP, we have a server with no video at all and RDP is fine.

Check your own warranty at http://h40059.www4.hp.com/warranty/ (ignore the fact it's UK and Ireland, the next page lets you chose any country.

There are fans inside the server to cool it, you should have a perforated door allowing 85% airflow and fill in any holes between servers and at the top with blanking panels.

Thanks for the info.  I will check this out, and also may try connecting straight into a monitor to see if it is kvm.
