1. Make sure your monitor is turned on first and working properly. If
you have another system, test the monitor on the other system to make sure
the monitor is functioning.
2. If you're getting power to both the system and monitor, but still
get no video, but you're hearing three short beeps from the system, then
your video may be loose or defective.
3. Open up the system and reseat the video card. If that does not fix
the problem, then try the video card on another system. If you still get no
video on another system, then you need to replace the video card.

1. Most likely this is because the refresh rate of your video card is
set too high for your monitor. If your display is OK when you're booting up the
system, before you get into the Windows 9x/NT desktop, then you need
to change your card's refresh rate.
2. To do this, keep hitting the F8 key when Windows 9x starts to get
into the Startup Menu. Then select SAFE MODE from there.
3. Once you're in safe mode, right click on an empty area of the desktop
to bring up the desktop menu and select Properties. Then select the Settings
tab and click on the Advanced button at the bottom.
4. Click on the Adapter tab and you should see a Refresh rate
setting at the bottom. Change it to 70Hz, 72Hz, or Adapter Default and
restart your system.

1. This may be caused by an incorrect refresh rate set on your video card.
See the question above.
2. Try adjusting the brightness and contrast settings on your monitor.
Setting the brightness too high on some monitors will make text appear blurry.
3. If the problem still persists, then you may have a defective monitor.

1. If you're stuck at 640x480 by 16 colors, then you haven't installed your
video card drivers, or the drivers are installed incorrectly.
2. To see which video driver you have currently installed, right click
on My Computer and select Properties. Then click on the Device Manager tab and
double click on Display Adapter. If the entry reads "Standard VGA" then you
need to install the drivers for your particular video card.
3. To do so, locate your video card's CD and put it into your CD-ROM
drive. Most CD will then auto start and prompt you for the driver installation.
If you're having difficulties with the installation procedure, please contact
the video card manufacturer or PREMIO product support for assistance.

1. If you turned on your system and you get no video, but you do hear
three beeps, then most likely your video card is not seated properly in the
PCI or AGP slot.
2. To correct this problem, turn off your system and remove the cover.
Locate your video card and reseat it. If it's a PCI video card, try moving
it to a different PCI slot.
3. With the cover off, power on the system and see if the video comes
up now. If it works, then put the cover back on. If you still get not video
or three beeps, try the video in another system, if possible.
1. If you have another system, try the video card in that system first.
2. If the video card still does not work, then you may have a bad
video card.
1. On some monitors, if the brightness is set too high, text on the
monitor will appear blurry or fuzzy.
2. Likewise, the contrast setting will have an impact on the text's
appearance. Consult your monitor's manual to try different
brightness/contrast settings, until the text on the screen looks sharp.
1. If the display on your monitor looks OK when you first power up
the system, but appear scrambled when you get into the Windows 9x desktop,
then your video card's refresh rate may be set incorrectly.
2. To do this, keep hitting the F8 key when Windows 9x starts to get
into the Startup Menu. Then select SAFE MODE from there.

to bring up the desktop menu and select Properties. Then select the Settings
