I know this isn't a forum about PC specs but I need serious help. My laptop graphic card (Acer Travelmate 4000 series with a ATI Mobility Radeon 9700 64MB ) just went berserk and the 3D graphs cannot be displayed (I think the card memory banks are screwed). I see some strange colors in some images and, when it needs to render something in 3D it's completely useless.

Does anyone know where I can buy mobility graphic cards? Cause if I can't it means I need a new laptop and, at the moment, I can't afford one :(
