1) Is the computer dirty inside?
When a Processor overheats it turns off. This is a built-in Fail Safe feature.
Keeps the Processor from burning up.

The Heatsink sitting on top of the Processor, and the Fan sitting on top of the Heatsink, keep the Processor within a thermal limit. (Temperature)
If they are dirty, the cooling capacity of these two components drops tremendously.

[ Typical construction of a Heatsink is a plate of metal that has tall, thin fins protruding from it.
The plate of metal absorbs heat from what ever object it is placed against. (In this case a Processor)

The tall, thin fins absorb heat from the plate, where they then radiate the heat away.
If a fan is used along with a Heatsink, the air flow from the fan draws heat away from the fins.
{Older computers did not use a fan along with the Heatsink.]

Typical example of a Heatsink/Fan combo,

Some computers do not have a Fan placed on top of the Heatsink.
A computer case fan in the front is used.
The fan pushes air through a plastic port, which covers the Heatsink.
(Think tunnel. Plastic port is a U shape)

Computer unplugged from power, computer case open, Observe Anti-Static Precautions.
Use a can of compressed air for computers, and clean the fins out of the Heatsink, and the fan's blades.

You may also find that using Q-tips to break the outside 'crust' will help.
The Q-tips are not used so much as to remove the dirt, dust, etc. But to break the outside surface so the can of air can remove it.

2) Thermal Paste: (Also referred to as Thermal Grease and Thermal Compound)

This is applied in-between the top of the Processor's case, and the bottom of the Heatsink.
It MUST be there, and in a gooey state.

Thermal Paste is used to transfer heat from the top of a Processor's case, to the bottom of the Heatsink.

The top of a Processor's case, and the bottom of a Heatsink are not perfectly smooth.
A microscopic view would show small 'Pits, Hills and Valleys'.

When the two surfaces of the bottom of a Heatsink, and the top of a Processor's case meet, these imperfections create an Air Pocket.

Air is an Insulator. Not a Conductor.
It insulates the heat from transfering from the top of the Processor's case, to the bottom of the Heatsink.

Thermal Paste is a Conductor.
It conducts heat from the top of the Processor's case to the bottom of the Heatsink.

Thermal paste can dry up. When it is dry it looses its conducive properties.
Check the thermal paste.

You have to Properly clean the top of the Processor's case, and the bottom of the Heatsink.
There must be NO old thermal paste left.
Then new, fresh thermal paste is applied Properly.

Thermal Pad;
A cloth like material that looks like a thin pad. Used on some older computers to take the place of thermal paste.
These are Junk, should be removed, and thrown away.
Once you remove the Heatsink to look, you can't reuse a thermal pad anyway.

3) You may have a bad Power Supply.
Power Supply's have Electrolytic Capacitors inside them. They are used as Filters. Used in the Input stage, and Output stage of the Power Supply.

Electrolytic Capacitors can break down over time to an unusable state.

{Electrolytic Capacitors DO break down. The design engineer knows this. After a given time they break down to a 50 percent level. The design engineer takes this into effect, and uses capacitors that are 50 percent better than needed}

The Electrolytic Capacitors used are Radial Aluminum Electrolytic Capacitors.

For simplification, let me state that they have an outside case made of thin aluminum.
Shaped like a 'Coca-Cola' can.
Inside this case is Electrolytic Paste
When the paste breaks down it forms a gas. Hydrogen gas.

The gas expands, and pushes paste out. The paste oozes out. (Pushes the paste against seals of the case, and breaks the seals)

So much paste loss, and the capacitor operates at a reduced level.
Too much paste loss, and the capacitor fails.

A weak, or a few weak capacitors can produce a weak voltage power rail in the Power Supply.
When they work good, the Power Supply produces power as it should.
When they don't, the Power Supply does not produce enough voltage, and the Processor turns off.

4) Motherboard;

Electrolytic Capacitors again.
This time they are used in the motherboard voltage regulator circuit.
Part of what the motherboard voltage regulator circuit does, is to regulate voltage to the Processor.

The Processor must have a Steady, 'Clean', supply of voltage.
A Processor has a VERY small tolerance range for voltage that it operates in.
To little, and it turns off.

Visual signs of capacitor failure,

Hi, I've purchased a 2nd hand LG 42" Plasma TV set

Usually black lines in a flat panel indicate an error or problem in the video board. A service professional can hook up to the tv and better diagnose the issue.

My mother board is intel 845gvsr,it not coming any display,before days it's working properly.but now it's not working,even bios settings also not showing.some times it's working but only 5 to 10 min only...

just a thought have you checked that its not shorting out on the case? when you installed the motherboard did you put in the spacers?
if you have then i would suspect the psu check that the fan it running when you switch it on

Intel mother board power light is on... but processor not working.. when switch on my cpu. the mother board powerlight displayed.mother fan is only one time run for sec.. processor not on

This is was with me too. I know how to fix it. Remove all cables from your cabinet, i mean like keyboard, mouse, moniter etc. Remove your ram too. Then press your power button from 30 seconds. wait for 10 mins plugin all cables and turn it on. Hope it works for you.

Best of luck.
