An Apple Store employee once told me that using Parallels on my MacBook Pro would void my hardware warranty. I am wondering, is this true? I was using parallels this morning and all of a sudden, my entire screen went blank with a whole bunch of shapes (differents shades of blue or yellow) everywhere. I rebooted my comp and my Windows XP partition was all messed up and wouldn't boot, and everytime I would boot up into MacOS X, the screen would get all messed up where I clicked. Accordingly, I am thinking it may be a video card issue, but I am wondering if my warranty is void because I have Parallels installed on my machine. If anyone has any info on this topic, please let me know. Thanks!
