How to troubleshoot a computer that displays a distorted screen upon startup.

The computer’s screen flickering on startup may be caused by hardware failure or driver issues, and you can try the following solutions:

1. Restarting the computer: Sometimes a screen glitch is only temporary, restarting the computer may resolve the issue.
2. Check the monitor connection: Make sure the monitor’s cable is securely plugged in and not loose or damaged.
3. Replace the monitor: If another monitor is available, try connecting it to see if the issue is resolved. If so, it indicates that the original monitor may be faulty.
4. Check the graphics card driver: Updating the graphics card driver may help resolve screen glitches caused by driver issues.
5. Check the hardware: If the above methods are ineffective, it may be a hardware malfunction causing the screen to be distorted, professional technicians can be contacted for a more detailed diagnosis and repair.

It is important to note that if the computer screen suddenly becomes distorted when starting up recently, you should consider if any recent changes have been made to the system or hardware, such as installing new software or hardware devices, as this could be the cause of the issue.
