I had a prebuilt however I've rebuilt it using the same motherboard and cpu. I have managed to get rid of the ugly logo on start up however when i go into the system properties the logo is there. My computer is basically custom built now yet it has that annoying logo which leaves the tramp stamp showing it's a prebuilt even though it isn't anymore.
