The problem might be lots of dust inside clogging up the fan. some people have opened the computer and cleaned out the accumulated dust. the fan then began to work and cooled the computer.

Really need more information, but my guess is dirty fan. If fan is blocked by dust, it may make noise and may run at high speed all the time because the CPU is overheating. If CPU gets hot enough, the laptop will shut itself down without warning. If dust is the problem, get some canned air. Before blowing into the air vents, try to spot where the CPU fan is and gently insert a toothpick to block the fan and prevent it from turning. A long blast of compressed air can spin the fan too fast and burn out its delicate bearings. Blow air from underneath and also from the side vent until air blows clear. In some bad cases of dust, the bottom or top cover must be removed to get it all out.

I have a Compaq C700 laptop, it powers on for 12 seconds then shuts off? Power is good, I have checked everything several times and can't get it to boot up? How do I fix it?

I think you have issues with the operation system ..cause there can be nothing else if all is ok physically ..So try first to reinstall the operation system using either a recovery disk or partition ..or use a boot-able disk with the OS on ..remember to be sure you have the drivers for it if you use a boot-able disk ..cause after a clean install there will be no drivers in the system ..
If after the installing will do the same ..or it will stop during the boot from cd ..this means it has issues with the ram memory or the CPU temperature(check the cpu fan and also the temperature set in Bios to be on the default value .....for this is enough to get to bios by pressing F10 on start ...and choose the function key indicated to engage the optimal factory defaults..)
There can be no other fault than the temperature of the cpu or the faulty ram memory ...or corrupted operation system ..

My HP g62 INTEL core i3 laptop encountered some problem of hanging.The CPU usage will go 100%, surely that cause of Hanging..What will I do? do I have to reformat it? how will reformat it!

usually this is happening when the cpu temperature is getting to the max..(cause of forced to the max of capacity ..) and the blue screen with the memory dumping kicks in and restart ..
first check the BIOS settings not to have a temperature limit set for the cpu ...and to do that just get to bios by pressing F2 on start (or del ) and in there look for optimal factory defaults..and engage them ...If you look around it is a feature with this name ..the function key is different from a model to another..) after engaging it ..just press F10 to save the settings and confirm with enter to restart ..
If it still makes the issue ..than the operation system and one of the programs running on it ..have a compatibility issue and you have to either eliminate the program ...(usually is the usage of a free antivirus ..on a recent operation system Vista or windows 7 ...and eliminating the antivirus and installing one from Microsoft may fix it ..o r...just roll back to an earlier operating system ..for example from windows 7 to Vista or XP ...cause it is not supported well by your system and makes it block itself.. I sow this problem a lot of times ..and I usually reinstall the operation system and install a windows XP ..and it is well tolerated with all the programs and such ..
To do so you will need a CD with a boot-able OS ..and the drivers for it ..for the devices..(at least the lan card driver to connect it to the net and seek the others after ) ..
here are some guidance for the installing process... it has a video too on the bottom and it is very accurate ..
installation for Vista is much simpler and all you have to do is to get yourself a dvd with the operation system (boot-able 0 and start the computer with the dvd in ...and also confirm by pressing any key the boot from cd ..and follow the tips ...It will almost install itself ..

The above as over heated and seems to fail after about ten minutes of being on this is an intergrated card can it be fixed without replacing the motherboard it is in an asus laptop.

I suspect that your cooling fan has stopped working or the sealing mating between the fan surface and the CPU is not intact. These fans quit working because dirt and grime gets into the fan shaft and friction slows the fan . also if the fan gets accidentaly moved on the CPU, then this breaks the heat transfer tape between the CPU. This over heating causes the CPU to fail. Open the machine and observe if the fan is running correctly.

When i start games on my pc the temperature increases to 100 degrees and pc turned off this start today before that i've played a lot of games and there was no problems like that

There is a chance your fans and heat sinks may be clogged with dust. This would definitely cause over heating and turn off your machine, if occurring within your CPU or the CPU on your graphics card.

Toshiba laptop fan speed up and then slow down issue. Feedback

I have a toshiba and that is exactly what the fan is doing to cool off the processor. That is because when you boot XP the fan stops after 30 seconds is simply it has no difficult operation on it. But when you choose to switch on to Ubuntu your fan doesn't stop is because ubuntu requires more air since it has so much effort on its operation. Mind you when you installed ubuntu, it requires larger video graphics memory than the XP OS. Try to execute more websites on different tabs on your XP and you will find your fan will work overtime because you put much required operation for the processor. But to help the fan cools off the internal devices, place cooling pad beneath the notebook so that your PC will be safe.

CPU fan issues

The fan may not stay on all the time - its a feature of laptops to help save power. The fan is also variable speed. As the CPU gets hotter, the fan speeds up. When the CPU isn't being used as much and is cooler, the fan slows or even stops. It turns on to full speed when you first turn the laptop on as part of the BIOS system check.

The noise is another issue. You could have a broken "fin" or fan blade. The bearing could be going out. Something may have simply "crawled" inside the fan's output vent. In any case it may be worth your time to have a professional open up the laptop and look at the fan. I have heard a LOT of noisy laptop fans in my day, and believe me it's not the worst thing to put up with.

The HP Presario A900 shuts down within 5 minutes of start up

If your laptop is overheating, it means that the Processor fan is not working. You can damage it further if you keep trying to us it. Although I must say, this is the first time I've heard of using frozen veggies to cool it down. I have a client that bought a portable Air conditioner to cool his laptop. I fixed it by replacing the fan.

The fact that the unit works while being cooled externally points directly to the fan.
Is the unit out of warranty?
If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
Thanks, Joe
