If you suspect your PSU is the culprit, it's crucial to address the issue promptly, as a failing PSU can potentially damage other components in your system.

Hardware failures, including issues with your graphics card, RAM, or motherboard, can also manifest as black screens. While these are less common than driver or overheating problems, they are still important to consider. A failing graphics card is a frequent suspect, as it's responsible for rendering the display. However, faulty RAM or issues with the motherboard can also cause instability and lead to a black screen. Diagnosing hardware failures can be challenging, often requiring component swapping or specialized testing tools. If you suspect a hardware failure, it's best to seek professional assistance to avoid further damage to your system. Ruling out other potential causes first is essential, as replacing hardware can be costly, and it's important to ensure that the replacement is actually necessary.

Finally, software conflicts or operating system errors can sometimes trigger black screens. Corrupted system files, incompatible software, or driver conflicts can all interfere with the proper functioning of your display. In some cases, a recent software installation or update may be the cause. Performing a clean boot, which starts Windows with a minimal set of drivers and startup programs, can help identify whether a software conflict is the source of the issue. If the black screen disappears in a clean boot environment, you can then systematically re-enable startup programs and services to pinpoint the culprit. Addressing software conflicts can often involve reinstalling the problematic software, updating drivers, or even performing a system restore to revert to a previous, stable state.
