However, if you just need to do a video card test from
your own computer then you can use a program like Sandra pro to test your
card.
One thing you may want to check before you do a video
card test is open up your computer and make sure the video card is properly
seated in its slot.
A video card can be subject to moving around a lot
because it is connected to your monitor by a cord and every time that cord
moves your card can move with it.
Make sure to ground yourself with the computer chassis
before you touch anything inside the computer. Once in there gently touch
the top of the video card to make sure it is seated tight.
If everything seems ok then you can start a video card
test. Video cards can burn out and it does happen.
You may need to just purchase a new video card if your
video card test shows nothing wrong.
