VGA Mode Not Supported Error
Question:When trying to turn on my computer, a Compaq Presario running XP, it appears to start loading (shows DOS screen) then goes blank with curser in upper left, the a message box appears that says "VGA MODE NOT SUPPORTTED" at the bottom of the message box is 'H:31.4KHz V:70.0Hz'. This happened a year or so ago and a local computer re installed windows (at the tune of $150) can you tell me if I need to scrap this thing?
Answer: It sounds
like your computer got set to a high resolution that your monitor will
not support. It may also happen if it’s really low like 640x480. It can
also be a case of your refresh rate being set to high as well. It’s hard
to tell if its Windows related without seeing how far the boot process
goes. If you can get into Safe Mode
then you can turn down the resolution and refresh rate. You should be
safe at 800x600. If you can’t get into regular Safe Mode then try Enable
VGA Mode.
If you get in then right click your
desktop and choose properties. Go to the Settings tab and adjust the
slider to 800x600. Then click on Advanced and go to the Monitor tab.
Under Screen refresh rate set it to a medium setting such as 60 Hertz.
Then reboot your computer and see if it will start in normal mode.
There may also be a chance that your
video card is having problems and may need to be replaced. You can also
test by hooking up your computer to a different monitor and see if you
get the same results.
