Method 3: to boot the computer in low resolution mode and check.
1) To get access to the Enable low-resolution video mode option in Windows 7, you will have to press
F8 key on your keyboard after the big logo or black screen with white texts appears.
On some computers you will see a boot selection after pressing F8, cancel that by pressing
Esc key on your keyboard and then press F8 key again.
2) First you might see an operating system selection screen - select the correct one there in case you have multiple operating systems installed. If you already pressed
F8 repeatedly, this screen might not appear, move on to next picture.
