Quick Fixes
Problem: When powering the system, all I hear is a loud and high-pitched squealing noise.
Cause: The graphics card is not receiving sufficient power required through the 6 pin PCI-E or 8 pin PCI-E power
connections from the Power Supply Unit.
Solution: Verify whether your card requires additional power connections. Depending on the model, these are
located at the back end of the card (opposite side of the DVI and VGA ports) or on the side of the card near the
back end. Ensure that you have connected the appropriate 6 or 8 pin PCI-E supplementary power cables and are
not using unapproved power adapter cables.
Problem: The computer will only display a black screen after it boots into Windows.
Cause: The integrated video adapter has not been disabled prior to installing the new PCI based graphics card
and/or not having uninstalled the display drivers from your previous display adapter.
Solution: Ensure that the integrated video adapter has been disabled through your motherboard’s BIOS or the Win-
dows Device Manager prior to installing the new graphics card and that you have uninstalled the drivers through
the Windows Control Panel. After the new card has been installed, connect the monitor cable and if required, any
supplemental power adapters to the new video before booting up the system.
Problem: At boot-up, all you hear is a series of beeps from the computer but see no screen at all.
Cause: The beep sounds are a warning sound from the motherboard BIOS that says that it cannot initialize the
graphics card. This can mean one of 4 things:
1) The card is not seated correctly.
2) There is a problem with the motherboard’s graphics card slot.
3) Supplemental PCI-E power is not connected to the graphics card.
4) There is a problem with the graphics card.
Solution: Remove the card from the computer and reinsert it, making sure that the card is seated properly in the
slot. Then try to boot the computer again. If this does not work then the problem is either with the motherboard or
the graphics card and you should contact your hardware manufacturer for further assistance.
