Hp heat sink

- Stop Overclocking your CPU.
- Make sure your Heat Sink is placed properly above the processor.
- Clean the Processor fan, Heat Sink and other peripherals.
- Use High Speed fans.
- Use CPU Heat Sink Paste in the processor.
- Fix OS registry with reliable program like I always use Reginout.
- Shut down your computer at least two hour a day.

Hope these tips will help.

It seems that your system is overheating so follow these instructions first
- Make sure your Heat Sink is placed properly above the processor
- Clean the Processor fan, Heat Sink and other peripherals
- Use High Speed fans
- Use CPU Heat Sink Paste in the processor
- Make sure your dint restrict the speed of CPU fan
- Shut down your computer atleast two hour a day
If you are unable to perform above tasks then use a single utility tool like PC Fresher that will fix windows errors that cause of overheating

that can be meaning if the processor is Not Supported with your motherboard,or the New Processor is not in good condition (can be Over Heat or damage).
Processor over heat or damage can be because the HEAT SINK (white or grey pasta at the top of processor) is not enaugh to cooling the processor or,the fan Proseccor is Dirty.

Processor fans are setup to nearly always blow air inward onto the heat sink that sits on top of the processor. The heat sink pulls heat off of the processor and the processor fan blows air onto the heat sink to cool the heat sink so that it can pull more heat off the processor. However, read the following link to see that it probably doesn't matter that much which way you put it: http://www.overclock.net/faqs/14695-opinion-****-vs-blow-way-do.html

I would definitely set it up with the processor fan blowing inward onto the CPU. If you're experiencing overheating you can try switching it to see if that helps. Use a program such as SpeedFan to monitor your computer's temperatures.

Good luck, please post back to this solution if you have any difficulties, and thanks for using FixYa.

How did you clean it?
The last one I worked on had the fins of the Heat sink totally blocked with dust. This will make the fan scream trying to push air thru the heat sink to cool the processor. If it isn't cooled it will shut down in short order.
You must BLOW it out. Use a pressurized air can. Better if you have a compressor with a nozzle.

The other issue may be the interface between the CPU and heat sink is defective. Heat sink moved or become loose.

Of course by this time the processor could be dead also.

that is problem of processor when processor is overheated it do so there is a white heat sink compound between processor and heatsink detach heat sink and apply new heat sink compound on the processor and look properly that heatsink is firmly fixed to processor or not .it may problem of fan if fan is rotating with low frequency then also it happens replace new fan the frequency of fan can be seen in setup

Just to answer your question about the heat sink arms being attached, yes it is imperative, should the heat sink fall off or isn't applied firmly your cpu could overheat and either fry it or causing severe damage to it.

I bought a faulty heat sink once for one of my old computers, put it in and ran the computer found out a little too late that the heat sink fan wasn't running.

Assuming that you are talking about the heat sink.

This device actually makes contact with the CPU and is held down, usually on four points, to the motherboard.

You will need to get some new CPU grease to put between the heat sink and the CPU when you re-attach the heat sink.

However, I would first examine the heat sink to verify that the "legs" are not broken. If they are, you will need to purchase a new heat sink.

Also inspect that the motherboard isn't broken. It normally isn't but you never know.

Good luck

God Bless

those r called as Heat sink Clip u can find in any radio shack or any HW Shop. make sure that befor u put the HeatSink put the Thermal Gel.

the hp dv8380us has an issue with the nvidia 7600 go graphics chip when the manufactured this laptop they didn't use the proper heat sink and heat sink compound so it causes the graphics chip to over heat. and when it over heats it causes errors as you explained. i also have a hp dv8380us  and have the same issues and haven't found a fix. mine also shows the picture 4 times as big as the lcd so i can only see 1 fourth of the picture i can see it fine if i hook it up through the vga port though. hope this explains your problem.
