I've had my G5 for a few months now (got it when it first came out). Its been perfect until recently my friend came up from college. He's been in my sight the entire time so its nothing physical, but he did install AOL which was horrifically buggy I can only imagine what else it did to my system. Anyway, now when my computer wakes up from sleep it freezes, or sometimes in mail it will get all squiggly and then freeze (once it got that way and unfroze which was a nice surprise). The strangest part is that when its rebooting the gray screen gets all like an old movie with the lines squigglying across it. I know im doing a terrible job describing it but I honestly dont know how else to explain it. It seems pretty stable otherwise, what should I do? Has anyone hads this problem before??
