Additionally, if there is a build-up of carbon dioxide or other pollutants in the ventilation system, these can cause health problems.

PSUs are often the cause of motherboard damage. They can create too much heat and be a fire breeding ground.

To clean them out, you’ll need to take care of the ventilation outlets first.

PRO TIP:

To clean the ventilation outlets, first power down your computer and unplug it from the wall. Next, use a can of compressed air to blow out any dust and dirt.

Be sure to hold the can upright and not upside down, as this can cause the can to leak. Lastly, vacuum up any debris that may have fallen out while cleaning. By taking the time

5. Incompatible Components:

Every motherboard has a variety of incompatible components. Some are listed on the product’s packaging, and some are not.

If your motherboard doesn’t list any incompatible components, it might still be damaged if your system has an incompatible component.
