O.K ....so a couple weeks ago, i put this screensaver onto a mates computer without him knowing, and set it to turn on after 30 minutes. First time it happened he didn't know what was happening so reset his pc, and thought nothing off it, he mentioned he had a blue screen appear and i had forgot about putting it in his system, oops ,, anyways to cut a long story short, this happened to him 3 more times, on the 3rd time, he put in his windows disk and done a full clean install. Double oops He knows about what i did now and all is good.
