Hey, I'd really appreciate any help with this. I have an HP slimline pc. It's just over a year old. Been having problems with the monitor shutting down more or less since I got the PC. First it was with some games, then on initial start up. It displays a message saying to check the video cables but this is not the problem. I have swapped monitors (which sometimes works for a little while and then the same problem happens with either/both monitors) and I have two imputes for monitors in the back, one direct and one I can use an adapter with to hook up the monitor, sometimes swapping between these works, sometimes no change.

The last time this happened the PC stopped recognising the monitor, keyboard and mouse, all were reliant on the back imputes. My front usb ports are shot and anytime a device is plugged into them the pc won’t start up (I think there's a short somewhere). So I reset the BIOS by removing the battery inside the pc and then reformatted and everything worked well for a while, until I updated with windows vista sp2, then the problems began when I tried to watch any video. It's taken me several attempts and restarting to get the monitor to work. I uninstalled the service pack and now the monitor works on start up but still fails when I play video (I can hear the video but have no monitor signal).

I get a warning message saying that 'the catalyst control centre is not supported by the driver version of your enabled graphics adapter. Please update your ATI graphics adapter or enable your ATI adapter using the displays manager'. The trouble is my drivers are all up to date and when I go into the catalyst control centre; my monitor is already active there. My resolution and refresh rates are not up at high. I keep them in the middle because of this problem.

Sometimes this problem is gone for months and then returns with a vengeance. I have tried just about everything but it's always a short term solution because I can't figure out what's causing the problem. Both monitor and PC are relatively new, drivers all up to date etc. It's driving me crazy now because I never know when it's going to happen.

Any help would be much appreciated :)

It sounds more like you need to sort your system motherboard or possibly PSU problems before you start trying to solve a specific video problem.

However...it would help to get a better understanding of where things sit (with no significant expense and relatively little time involved)...you need to get Vista and all its drivers, Catalyst, and etc. out of the picture.

Download and run freeware self-booting UBCD and run the system, memory, video, and CPU diagnostics.

Assuming NO problems are found with diagnostics, then...
Download freeware Ubuntu Live and/or freeware Knoppix Live and see if your various problems remain under those OS environments.

Do you have both Analog and DVI plugged in? Try reinstalling the graphic drivers, uninstall, restart, install.
