I have had Windows Xp installed on my late 2009 MacBook Pro for a couple months now, but all of a sudden, when trying to boot XP, i click the icon and it just goes to a black screen with a flashing white line. I have up-to-date virus protection on the XP side and do not think that could be the cause. The only differences on the Mac side are that i have installed Paragon NTFS 8.0, Photoshop CS5 Extended, and Squeeze, by latenitesoft. I laos changed the BootCAmp icon on my desktop to a different image, but after restarting from the black screen with flashing white line, the BootCAmp image restored itself to the original one. I googled the problem and saw that it was a hardware problem. I just want to know what could have caused this and how can I fix it?
