Computer Troubleshooting - How to Stop Your PC's Overheating

The danger with a computer overheating is that internal components will be burnt out and damaged beyond repair. This is normally fatal for a PC and may result in data loss (especially if the hard disk is involved). This article looks at using the BIOS for computer troubleshooting heat problems with the CPU/fans, and how to prevent this from happening.
Start by checking the heat monitor levels for your CPU. All computers monitor CPU temperatures and fan speeds via the BIOS. You can access this data by booting up the computer in BIOS mode (usually by using the delete key as the system boots). The BIOS menus should contain sub-menu items for monitoring, CPU temperatures and fan speeds.
Alternatively, freeware tools like SpeedFan and HWMonitor can present these BIOS monitor readings as your computer is running.
Check that the fans are running and that the CPU temperature is below 50 degrees centigrade. Intel recommends a maximum temperature of 40 degrees as the PC idles and 50 degrees under heavy load. If your CPU levels are nearer 80 degrees then you have serious overheating issues.
Computer troubleshooting heat problems involves (i) cleaning the internal components of dust and (ii) reducing the computer's exposure to external heat sources. Open the PC and use compressed air to clean the vent inlets, CPU heat sink, fans and power supply. Do not use any liquids for cleaning (as it causes corrosion).
With the computer cleaned, ensure the PC is not kept beside a heat source or that anything is blocking the vents. Laptop users should be careful to place their computer on a level surface to avoid blocking the vents underneath.
If the detected heat levels are still high then you have to check for damage/faulty components. Check for cracks in the vents/heat sink or damage to power cables and connector pins. Replacing damaged fans won't cost too much and is easily done by a PC repair shop if you are not comfortable doing this.
