    Clean your computer. Your computer can grow dusty in less than a year, depending on where it is stored. Open it up depending on how dusty your house is. If it's not too dusty, then check every few months, but if it's super dusty (your house), then be much more proactive about it. Remove the dust on the bottom with a vacuum (or cloth), then spray with compressed canned air. Pay special attention to the CPU heat sink and CPU fan. Hold the fan still while spraying it as you can cause it to spin out and on reboot it may have more noise. Spray the intakes to the Power supply fan also. Since you have the cover off reboot and listen for noisy fans make sure all fans are working. Replace the fan if it stops spinning or starts making unnatural sound or you can try to lubricate the bearing, this might help.
