Hi i found a used Built By ATI Radeon 9800SE 128MB AIW from my previous system it's the 256-bit model and i haven't overclocked or unlocked the 4 additional pipelines however i am having a problem with the card. I bought it for my Media Center. I tested it in my main pc until my cube system arrives however there are lines and artifacts all over the screen. The card is recogised by windows and plays 3d games it just the display both when boot and in windows is garbled text is garbled and line appear all over the screen not always in the same places. Any idea i want to get this card working thanks. also i know it is not my board because my Ideq 200T arrived today with the same results If it don't work try hitting it, then if that doesn't work buy a new one :P

Does that card require the extra plug-in from the power supply?

"....there are lines and artifacts all over the screen." "...it just the display both when boot and in windows is garbled text is garbled and line appear all over the screen not always in the same places." The only things that can cause that is the video card is damaged, or it has a poor connection in the slot it is in. Remove the power to your case, turn off your monitor, open up the case, make sure the video card is all the way down in it's slot and parallel to the mboard. Take it out, put it back in if you need to. If that doesn't help the video card is no good. NOTE that ATX power supplies are always powering ATX mboards in some places including some contacts in the video slot, even when Windows is Shut Down or in Standby or Hibernate modes. If you did not remove the power to your computer case when you installed the card, it is quite possible to damage the video card and/or the video slot while installing or removing it from it's slot. "Does that card require the extra plug-in from the power supply?" If it's an AGP card, no it doesn't. However it does have a chipset fan on it, and if that isn't spinning properly the chip it protects could be damaged.
