Hi, I have 2 Monitors in my Mac Pro (2006)...so I was arranging my studio and just for the meantime connected only 1 monitor and the Desktop looked weird, like the monitor size setting was not right...I could not find a Setting that was right, but I thought was because I was using in the meantime only 1 monitor...I did not care.... but all the folders were all on the side of the screen all crunched together. Anyway next day I could nor boot the computer...and after the grey Mac logo I get a dark screen with the pointer in the upper right corner....weird thing is that I can move the mouse but still there a pointer arrow frozen in the corner. I was not able to boot with the CD or install again the Mac OS. -I was thinking can be a bad capacitor. -The Graphic card is damaged...(but why I can see the Grey Mac Logo fine?) -Or maybe the logic board is bad (again..maybe a bad capacitor?). I did a Hardware test and in the fast test do not show any problem. in the long test say: 4SNS/1/40000001:VMBS error. Any advise? Thanks!
