Troubleshooting a bad video card.
Question:
Troubleshooting a bad video card.
Answer:
Note: Unless you're sure you're troubleshooting a bad
video card before following the below steps we suggest you go
through document CH000241 for steps in
troubleshooting no display. No display can be a monitor related
issue, no post issue, and/or a video card related issue.
If you've determined that your video card is bad or that it's the
next likely culprit for your computer issues you can troubleshoot a
video card by following the below steps. Each of the below steps
will require that you open and work inside your computer. While
you're working inside your computer make sure you're aware of the
potential ESD dangers.
Reseat the video card
If your video card is not an
on-board video card verify
that your video card is not loose by removing the video card from
the computer and then re-inserting the video card back into the same
slot it was removed.
Exchange video
If reseating the
video card has not resolved the issue or your video card is on-board
and you have access to another known working video card. Try an
alternative video card in the computer.
Replace video card
If an alternative video card did work or you do not
have an alternative video card to try we suggest purchasing a new
video card to replace the defective video card in the computer.
Buying tips for video cards can be found
here.
If an alternative video card didn't work replacing
the video card with a new video card will not resolve the issue it's
likely a defective motherboard and should be replaced.
Replace motherboard
If all the above steps have not resolved the issue
it's a bad motherboard. If you feel comfortable replacing the
motherboard you can find buying tips for motherboards

computer serviced at a local computer repair shop.
