Doesn't matter if it's intergrated or not, go to control panels device manager, click the plus sign left of 'display adaptor' and see the identity of your adaptor.
If you still haven't got it resolved, while there install thru: 'add new hardware', a standard super vga graphics adaptor. Also a standard super vga monitor, select the devices yourself, windows will install generic drivers which should correct most of the problem until you can identify the adaptor and update the drivers, and install the correct monitor.
Anytime you format, windows will usually default to the basic drivers= 640X480, 16 colors.
