[QUOTE="chscag, post: 1336897, member: 46727"] Try this test for us: Take a screen shot of your desktop with the blue vertical line and dark spots. Examine the screen shot to see if the same blue line and dark spots show up. 1. If the screen shot is clear (normal) that means the problem could be caused by defects in the LCD itself. 2. If the screen shot looks the same (blue line and dark spots) it could be a problem with the graphics chipset. Post back and let us know and we'll go from there. [/QUOTE]
