Restart, and before windows starts press the f8 key to enter set-up mode (or it may be f5), select last known good configuration, press enter. this should reset it.

My monitor is displaying sideways on a hp montior


It sounds to me like you have Hotkeys enabled and accidently pressed them.

To rotate screen view you can do the following using the keyboard arrow keys in conjunction with pressing CTRL key and ALT key at same time:

Ctrl-Alt-Up - right side up

Ctrl-Alt-Right - 90 degrees

Ctrl-Alt-Down - 180 degrees

Ctrl-Alt-Left - 270 degrees

To locate HotKeys and disable navigate here:

Start >> Control Panel >> Display >> Settings >> Advanced

Subject to your monitor/graphics card you may need to click a few mor tabs to see HotKeys.

Hope this helps. Best Regards -md

Changed graphics card-then disabled the monitor by accident, now black screen.Not even safe mode works now!


That's pretty funny (apart from the suffering)! It's doing exactly what you asked and displaying nothing to that monitor. Even if you safe-boot, the VGA thing might try to honor the setting (though it shouldn't if you have WinXP SP3.)
Booting to a command prompt 'only' from the safe boot choices and importing some regedit settings from another machine's video might just do the trick. (As well might adding a 2nd monitor on some machine and seeing what changes in the registry using a monitor program for that.... Some 'display' key probably contains 'disabled 1' instead of 'disabled 0'.... )

If you can get a LiveCD or bootable USB key of any sort (WinXP, Knoppix, Kevin's Rescue CD, etc.) you can probably just enjoy graphics settings by booting to that, and edit the registry or use WINCONFIG a little more freely than Safe Boot offers.

No signal to monitor


  1. Verify card is seated properly.
  2. Check bios settings. ie. disable onboard video, enable PNP OS installed, enable "assign IRQ to vga", disable shadowing and caching, enable passive release, enable delayed transaction, vga boot sequence: AGP, set graphics aperture size to 128MB, disable turbo modes.
  3. Verify power supply is at least 350 watts.
  4. Reboot into safe mode (press F8 right after the BIOS POST screen and before the windows loading screen) and use the program, Driver Cleaner Pro to remove Nvidia video driver remnants. Don't select all of the options, just the Nvidia driver and the plain ATI selection.
  5. Verify the monitor cable is securely connected to both the monitor and the computer.
  6. Verify that you have connected the cable to the vga port on the card and not the onboard vga port. (I'm not implying that you are dumb or anything like that, but sometimes even the best of us, overlooks the simple things... especially me! LOL)
  7. Verify the monitor cable is good.
  8. (Last but not least), try using another monitor to test. (Could be an incompatibility with the monitor.)
