Question about HP 8710w Mobile Workstation - Intel Centrino Pro Core 2 Duo T9500 2.6GHz - 17" WUXGA - 2GB DDR2 SDRA... PC Notebook
I had similar problem on my HP 8710p and eventually fixed it. Here is how.
First I had a normal overheat situations twice due to clogged dirty fan vents over a period of 4 years. You notice this when the vent cooling fan stays on most of the time, unlike when it was new, even while idling, and of coarse one is reluctant to break open new a PC. After eventually cleaning the fans the problem was resolved but the PC was actually operating at slightly higher average temperatures as the cooling fan would switch on more often that it did when it was new. This is so suttle it did not concern me at the time me until eventually after 18 months, a mere boot would send the cooling fan into frenzy of cooling mode and usually switch the PC off before a full boot could be achieved.(and yes my cooling fins were spotless as I cleaned these once a month at this point).
System reboots were a nightmare as I would have to wait for 30 mins for the CPU to cool down. Eventually I lifted my keyboard on the left side and slipped a small 5 volt fan onto the processor. The fan was powered by a USB port. This worked great but directly cooling the CPU also meant directly depositing dust directly onto the inside of your PC which had to be cleaned with compressed air at least once a week. That was besides the fact that I had to contend with a lop-sided keyboard because of the fan height.
After a year of this I finally I decided to rather try replacing my CPU as I had run out of options. While searching eBay I discovered that CPU cooling apparatus'us were sold in conjunction with CPU's so I decided to buy the cooling apparatus first as a replacement CPU was pricey, especially for an older PC. Skeptical about about my decision, I replaced the CPU cooling apparatus.
To my amazement the problem was solved. Where before I could not even touch the copper tubing near my CPU with my bare finger, now it was cool, probably no more than 30 C and booting was silent. Needing to be sure of this, I replaced the previous cooler and the problem returned, the CPU cooling apparatus copper evaporated spit near the CPU and miraculously cooled down to a room temperature on the fin end.
This was difficult to understand because copper is a very good conductor of heat and here clearly was a situation where the one end of the copper tubing was hot enough to boil spit and the other was at room temperature.
So what can cause this? I am not sure exactly but its not mentioned any where on the Internet as a fix, Not even by HP themselves.
I suspect initial over heating may have messed with the internal climate system in the copper tubing to the extent that the coolant dissipated, probably due to high pressure. The faulty cooling apparatus did not demonstrate any signs of ware and tare, actually the replacement cooling apparatus looked worse than mine as the copper had lost its sheen. I also examined the faulty apparatus from close up for any possible cracks and holes and found nothing visibly wrong. All I had to go on is that the replacement worked and mine did not.
My CPU now peaks at around 50 C when number crunching and the cooling fan is seldom activated. The copper tubing is warm, but not hot, right up to the area where the CPU is located. My system runs so quiet now it has a feeling of newness about it. That raises another question, modern PC's have normally have self preservation software coded into their BIOS that prevents or slows down the CPU clock speeds when over heated or running on battery. The battery part is to conserve power but the heating part is to not do irreparable damage to the CPU. This feature is usually referred to as "dynamic clocking". A hot CPU will run at the slowest possible speed it can function at, (beyond this it will be shut down) at a time when you are trying to crank every bit performance out of it. So it goes without saying my PC now runs faster and appears to be more responsive, just like the day I bought it.
While this occurred to my HP 8710P, I know the problem occurs to many aging laptops that can by fixed the same way. Currently there are many alternative external CPU coolers being sold to solve this problem(and I have seen many and the ones I purchased I have returned). I believe that Trojans and viruses are not always responsible for sluggish PC's. Until you address the real issue, your problem will continue. Consider the above as an option.
My PC was headed for the trash heap. (I am a developer, not a gamer) but now it will stay. Its reliable, trustworthy and never had a problem besides the cooling issue.

If you already have a Virus scanner, that updates regularly you can skip the Malware scan.
I would suggest three things. A Malware scan, a maintenance cleaning, and checking your Start-up applications.
To run a malware scan go-to: www.trendmicro.com/housecall
And follow the instructions on the page, let this run, until the results dialogue window pops up, this make take a while. 1-3+ hours. Just let it run, you do not need to attend it once it tells you it is scanning.
For maintenance cleaning, visit this site to download an application called CCleaner
After these steps.
To adjust what programs you have starting up in the beginning:
Start > Run > Type "MSCONFIG" > Click the Startup Tab then un-check any program entries that you don't need starting up in the beginning. This does not remove them from your computer, just from starting up in the beginning and taking resources in the background. When you need the program, you can simply click on its link in your start menu. It is your choice what you keep and what to remove.
If these steps do not solve your issue, there may be a complication with your Audio Hardware acceleration. To rectify this issue:
Access your control panel:
Start > Control Panel
Press and Hold "Windows Key Logo" + Press "E" > Click "Control Panel" from the left-side menu (or address bar, depending on your configuration.)
Once their click "Sounds and Audio Devices"
While in the Audio Devices window:
Click on the "Volume" tab and click on the "Advanced" button under Speaker settings.
Click the "Performance" tab > drag the slider for Hardware Acceleration to none.
These directions are for Windows XP generally, but you should find the location is similar in Vista.
It is important to note that this procedure should solve your issue; however, in the event that it does not, this procedure does increase the performance of your machine dramatically. Nothing will be harmed if these steps are followed in their entirety.
If these steps do not solve the problem, please let us know. If this information was helpful to you, please take a moment to rate the solution. Thank you.

SOURCE: overheating hp compaq 6735s
The overheating problem can be caused by a faulty fan and or dust clogging the fan and heatsink assembly. If the fan deos not spin freely then it is faulty, also loosen the dust and vacuum the dust from the fan and heatsink.

The overheating can also be cause by the battery. Please check the following article link as it lists models affected. There's also a link in the article, if you need to contact HP's battery replacement program.
