If you’re facing a blank screen on your PC despite it turning on and fans spinning, follow this comprehensive troubleshooting guide to identify and resolve the issue:
Wait and Reboot
Before taking further steps, wait a few minutes as your PC may be reconfiguring memory or initializing USB ports. If the screen remains blank, try rebooting the PC.
Check the Monitor
Ensure the monitor is powered on and correctly connected to your PC. It should display an indicator when powered on, even if it doesn’t display anything else.
Check the Post Code
If your motherboard has a post code readout or displays a specific beep pattern, consult the manufacturer’s manual to determine the issue. If there’s no display or beeping, continue with the following steps.
Reset the CMOS
The CMOS stores basic BIOS/UEFI settings for your motherboard. Resetting it can resolve boot issues. Refer to the motherboard manual for instructions on how to do this.
Remove Unnecessary Components
Unplug all external devices except for the keyboard, mouse, and monitor. Then, remove internal components such as add-in cards and secondary storage drives. Try booting your PC again.
Double-Check the Memory
Memory problems can cause boot issues. Swap out or remove memory sticks one at a time to test if they’re the cause.
Consider the CPU
Remove all memory and try booting the PC. If you get a different error code or beeps, the CPU should be fine. If not, it could be a CPU or motherboard issue.
Inspect for Physical Damage
If all else fails, inspect your motherboard, graphics card, memory, and processor for any signs of physical damage or stress. If you find anything damaged, try replacing the component.
Conclusion
By following these steps, you can troubleshoot and resolve the issue of a black screen on PC startup. If the problem persists, consider testing each component individually or opting for a new PC.
