Where Can I Take My Video Card To Be Tested?

I think my video card is defective but I need to test it out on another computer to be sure. But I only have one desktop and none of my friends will let me try it on theirs. Where can I take it where they can tst ti for me on another computer? Will a local computer repair shop or something do it?|||Yes go to any local repair shop they will be able to let you know if you need a new card by testing it and can advise you on which type and power you will require should you need a replacement. New Cards start at around £25. and go up to £500.
