The computer works fine for a few hours and then freezes

Cause: If your Systems CPU is Overheating this symptom is typical of overheating. Overheating processors are a major source of PC freezes and crashes. Mainly two types of CPU overheating main processor and graphics processor the main processor or the graphics processor can overheat and bring the entire PC to a grinding halt. The CPU, and graphics processor has its own heat sink and fan. An overheating main and graphics processor would point to some problem with the cooling system.

Solution:

1.     Eliminate all the other heat generating culprits first

•    Check the power supply
•    The CPU heat sink and fan.
•    Use thermal paste if necessary
•   Clean the Processor fan, Heat Sink and other peripherals.

Note- It may be that the fan is not working or the heat sink is not fitted snugly on the graphics processor. Check the power connections for the fan and reseat the heat sink to fit it tightly with the processor.

2.     Such graphics cards should have a temperature sensor that can be viewed from within the operating system. This would give you a good indication of whether the card is overheating. Unless you are stressing out the system with high-end 3D applications for hours on end, it is unlikely that the graphics card is your source of trouble. In most cases it would be the power supply. But the sudden freeze and shut down is typical of overheating, so look at the CPU and PSU again if you have ruled out the graphics card as the source of the problem

3.     Check the Power management system in Bios – Check fan speed and fan controlling system. BIOSs have fan speed monitors. Watch those for a bit and compare them to what the PSU says is a reasonable speed.

4.     Correct Airflow- choosing the right case is critical for avoiding computer overheating. As hot air has a natural trend to move upwards, the hot air produced by the computer automatically flows to the upper part of the case. The power supply’s fan then draws out this hot air, thus providing proper computer ventilation. Cool air automatically comes in through the case’s front via a suitable slot placed under the space intended for the hard disk.

5.     Use Additional Cooling Units -A good gamer is not one who only chooses the best processor and Graphics Unit, but also one who protects it by adding a suitable cooling unit. These days you get liquid cooling units for a cheaper price. Consider using any of these to keep your CPU temperature normal.

6.     Shut down your computer at least two hour a day-Be in whatever field you are, and for whatever purpose you use the computer, make sure you leave it shut down for at least 2 to 3 hours a day.

7.     Check your SMPS -As I mentioned earlier supplying a lower voltage to the CPU may reduce the CPU fan speed, SMPS power unit may be damaged sometimes, giving a lesser voltage than they actually required amount. So check your SMPS for normal Voltage Supply. There are two symptoms of this, Firstly the CPU restarts often and secondly you can notice your Fan Speed going down.
