    Well, today, everything with my PC was fine, until just an hour ago I woke the computer up from standby. It SEEMED OK, until it randomly switched to 640x480 resolution. I tried right-clicking the desktop and went to Screen Resolution, but the option to change it was greyed out. So then I went to Device Manager and tried to Roll Back the Driver, but when I did that, my PC crashed (screen went black for 10+ minutes) and I had to turn it off via holding down the power button. I rebooted into Safe Mode, and tried doing a System Restore to a time I knew worked. However, I still rebooted into the horrible 640x480 resolution. So then I went into Device Manager again, and uninstalled the Driver. Then I went to Programs and Features and uninstalled ATI Software Install Manager, ATI Catalyst Control Center, ATI Video Driver and ATI HDMI/DP Audio (basically uninstalled eveything to do with ATI). Then I downloaded the driver for the display adapter from HP, and installed it. Still, the same problem. I ran a virus scan and everything seems OK. I've exhausted my knowledge and need your guys' help.

    PC Specs:
    HP EliteBook 8740w
    Intel i5-560M'
    ATI FirePro M7820
    8.0 GB RAM
    Windows 7 Professional 64-bit

    It is possible that you video card went out, is it still under warranty?

    Yeah, it is.

    It says "1|2. Multiple Monitors". If I click on advanced settings and click the adapter tab under it lists my card correctly. If I click on the monitor tab it has "Generic PnP Monitor" and "Generic Non-PnP Monitor" which neither seem to work. I've never connected my PC to another monitor via any of the ports -- I only use/have the built-in laptop one.

    Backup all your information. Reformat the HD.
    ^ Fixes all software problems.
    If it's hardware. You're kind of F'd unless you're under warranty.

    Can I use a different CCC for my card (like the stock one)? I'm thinking I'll take the backup/reformat suggestion. I've had stability issues with the HP drivers before... although they never messed up quite like this before.

    You will need the default HP Driver first before you add on CCC. It is the only way the CCC will detect the FirePro from a Radeon Catalyst POV.

    Well, it doesn't appear to be a hardware issue. After reinstalling Windows and applying my backups, everything seems to be in correct working order. Still unsure as to what happened, though.

    Annnndddd guess what? Fresh install, and it happened again. I was able to get my screen resolution normal, but I have to go right-click the desktop, select screen resolution, and select Show Desktop only on 1 each time I start my computer. I might pop in a Linux DVD to confirm its a hardware problem, but at this point I'm fairly certain it is, especially the way it acts before it happens (screen going on/off in random intervals a random number of times).

    This stinks. Gonna have to have HP come out AGAIN.

    EDIT: Dandy, I have to do it when I wake up from standby/hibernate as well. This is not supposed to be like this.
