Troubleshoot differences between hardware and software problems

Display problems can be detected in any of the computer's three different graphic states: BIOS level, Windows (OS) level, and Advanced Graphic Chip state. Visual irregularities that are noticeable only when the computer is in operation can usually be adjusted using updated Windows or graphic chip drivers. However, physical damage that will require repair or replacement can usually be detected in the BIOS level operations before the computer boots into Windows. The cost of replacement parts and service will vary based on the exact problem and the location of repair facility.

If the display is blank (either all black or all white), or the image is cracked or distorted during the boot process, there is probably some physical damage that will require repair or replacement.
If the image is clear in the BIOS state but distorted in the Windows state, it may be possible to correct the problem by installing the latest BIOS, CPU chipset, and Windows graphic drivers.
If the image is normally clear but becomes distorted when running a specific program with high graphic requirements, like watching videos or playing on-line games, it may be possible to correct by problem by changing the screen's resolution or installing updated drivers from either the graphic chip maker's site or the application manufacturer's site.
