Clean Inside PC Case

Your computer can overheat, reducing its life.  It is recommended that you clean inside your case every six to eight months.  Do it every three months if your case sits on the floor, you have pets that shed, or if you smoke.

Using a screwdriver, remove the side of the case that's opposite your motherboard. Touch as little as possible inside the computer, keeping fingers away from cards and cords.

Blow air around all of the components and along the bottom of the case, keeping the nozzle four inches away from the machine. Blow air into the power supply box and into the fan (from the back of the case). Lastly, blow air into the floppy disk and CD drives. Wipe the inside of the cover with a lightly moistened cloth before replacing it.
