I have a problem here and want suggestions to solve it. Actually its the problem with one of my friend's computer. A few days back he encountered this problem. While the PC booting, the screen becomes narrowed from two sides as if squeezed. When windows is loaded it becomes fine again. He has dual boot, one Windows 8 and the other is Windows 7 Pro. In both cases the same thing happens. The monitor is narrowed only while booting. He has a widescreen LED Monitor (17").
Any suggestion will be appreciated. Thanks in advance.
