Hot CPU, or are you trying to refer to the computer itself? CPU stands for Central Processing Unit. Another name is Microprocessor, or simply Processor for short.

1) Clean out the inside of the computer, with a can of compressed air for computers, and you may also have to use Q-tips to dislodge the heavy 'Gunk'.

2) Make sure the computer case fan/s are operating, and they are not spinning too slowly. (Bad fan bearings)

3) Assure that the Processor fan is operating, and not spinning too slowly. (Or spins a few times then stops)

4) Assure that the Thermal Paste used in-between the top of the Processor's case, and the bottom of the Heatsink, is in good repair. At the cheap cost of replacing, it's best to just clean the Processor's case top, bottom of the Heatsink, and correctly apply fresh thermal paste. IF a thermal pad is used, remove it, fly it at the cat. Thermal pads are JUNK, and can't be reused anyway.

BEFORE you reach inside your computer.

Observe Anti-Static Precautions.

Anti-Static Precautions:
Your body carries Static electricity.
Static will fry out (Short Circuit) the hardware components inside a computer.
(Some examples: Processor, Ram Memory, motherboard chipsets, etc.)

Computer UNPLUGGED from power, computer on a table, computer case open. TOUCH the metal frame of the open computer case.
This will relieve your body of Static.

Should you walk away in the middle of working on your computer, upon your return be SURE to Touch the metal frame again.

    NO, if you have a thermal pad DO NOT fly it at the cat after removing. Was J/K.
    (I can see it now. News headline. Expert moderator on FixYa.com, tells asker to fly thermal pad at cat. Cruelty to animals. Cat's can't work on computers )

Well if the CPU gets hot it will shut down...
no ifs nor buts nor maybe it will shut down, reason being the cooling system and the fan is meant to keep the processors cool and if they over heat then the system cannot perform or stay up, it may be the fan so check into that if not run an hardware diagnostic on your system...
to do the hardware diagnostic go to;
CMD the type the chkdsk in the box and hit enter..
you can also do CHKDSK /f to fix errors or CHKDSK /r to repair errors... but those would not be with overheating and shutting down but regular chkdsk should get you an asnwer if anything is wrong hardware related...

Auto restart


Your machine is rebooting itself while you watch a movie on it? Could be a couple of things. First, is this a laptop or desktop? When is the last time you updated your video drivers? If this is a laptop, does it get very hot just before rebooting?

Theories work like so:
1. older video drivers can be causing a cpu panic condition due to a bug. This is more common with PC games vs. watching movies, but still possible. Updating your video drivers may help fix the problem if that's the cause.
2. heat: if the computer overheats, it will reboot to protect itself. As for why it's getting hot--could be that your video hardware or cpu is getting too hot playing the movie. Could be that your cooling fans are bad. This is why I asked about the machine getting hot.

Another possibility is the need to update either your BIOS or hardware drivers.

Please post more info if you require additional help.

Does it boot up into windows and allow you to work on it before it shuts down? Or does it shut down during the boot up process?

It sounds like it might be running hot or you have a virus or infection that causes it to shut down.

One sure sign of a computer that is running hot is to try and restart it as soon as it shuts down. If it's running hot it will not restart until you let it sit a while and cool off, then it will restart successfully.

Three things that will make a computer run hot:

1) Dust - Dust inside the computer, dust clogging the vents, fans, cpu and heatsink. Solution- Remove the case and take a can of compressed air and blow out the dust.

2) A Fan not working. Make sure the cpu fan works and the fan inside the power supply. If not replace them.

3) The Thermal Paste around the cpu and heatsink has dried up or is too thin to keep the unit cool. Remove the fan that sits on top of the cpu and heat sink, remove the heatsink, release the latch that holds the cpu in the slot and remove the cpu (remember how it goes into the slot). Clean off the old thermal paste then put the cpu back into the slot and put the latch that holds it back on. Put a fresh coat of Thermal Paste on the cpu. Turn the Heatsink over and remove the old thermal paste from it and apply a fresh coat of Thermal Paste. Put it all back together and reboot.

Download and Install MalwareBytes and run a Quick Scan.

Go to www.google.com and in the search box type: "Download cnet Malwarebytes" (without the quotes). Download and install malwarebytes from the sites download.cnet/malwarebytes. When the site opens up click on the Green Download button on the left. Do not click the Red Download button, that's junk. When it finishes installing the Gui Interface will open up with an offer to Accept a Trial Version or Decline. CLICK DECLINE you want the totally free version. Run a QUICK SCAN. As it scans, if it finds infections the number will be in red. When it finishes scanning, click SHOW RESULTS. A notepad text document will open up showing you the results. You can close the text document and go back to the Gui Interface where you will click REMOVE SELECTED RESULTS. The objects will already be selected for you. When it finishes removing the objects click ok and it will sometimes reboot your machine.

Why does my computer keep restarting?


It's either running hot, you have a device conflict or a virus.

Try running a virus scan to make sure it's not kicking you off. Check your devices in the device manager to make sure all drivers are loaded.

Remove the power cord, remove the case, take a can of compressed air and blow out the dust from inside the computer, around the vents, around the fans.

If it still runs hot after the above steps, remove the fan that is on top of the CPU and Heat Sink. Clean the dust and apply a fresh coat of Thermal Paste to the CPU and Heat Sink.

Computer shutting off


shutting off when? Shutting off immediately when you try to start it? Shutting off after it has run for a while?

If it is shutting off after it has run for a while, then it is probably running hot. If you try to restart it immediately it will not boot. If you let it cool off for a while then it will boot successfully (definitely a sign of running hot).

Things that make a computer run hot:
1) Dust in the vents, fans, cpu & heat sink and all inside the computer.
2) Fan not working
3) The Thermal Paste on the cpu and heat sink has either dried up or is too thin to keep it cool.

If it shuts down immediately after it has been sitting for a while then it's not running not and your system has some other problem.

System restart even playing game gta3


If your CPU or GPU aren't capable of running the game your computer might be overheating. Restarting itself is a safety measure built into the system. Trying checking your computer CPU temperature and make sure its not getting to hot. I use CoreTemp to check things like this. It will show all the info you need for your CPU. Google the CPU model for temperature specs from Intel or AMD depending on your computer. If it seems to be getting hot make sure your fans inside the computer are operating and also blow the dust inside the machine out regularly. Only other thing i can think of is you might be hitting a bad spot in your memory (RAM) but usually that results in a blue error screen then restarting.

My computer turns off and on again for a few seconds. (this time it will bootup) when i pressed the power button. i already change the ram to 1gb but the problem still occurs. What can i do to fix this...


It may be owe to software problem 1, the virus "shock" virus attack will prompt system will automatically start in few seconds. From the remote control you Trojan program all the activities of the computer, including let your computer restarts. Remove viruses, trojans, or reshipment system. 2, the system files damage system files destroyed, as the KERNEL32. Win2K DLL Win98 features, the font list below such basic execution system files destroyed at startup, system will therefore cannot finish initializing and forced the restart. Solution: cover installation or reinstall it. Hardware problem: 1.Chassis power is not enough, dc output is pure, the dynamic response sluggish. Users often ignored or assembling businessman, using cheap price of power supply, so is the largest system of automatic restart suspicion. (1) the power output power shortage, when run large 3D gaming occupy CPU resource of software, the CPU needs power supply, power is not caused by overload protection, stop the power output. After the output power to stop, load, reduce power restart. Due to the protection of the recovery/time is short, so we are hosting automatic restart. (2) power dc output is pure, pure dc power supply of digital circuit requirements, when the power output of too direct, the harmonic content will result in digital circuits, performance is often work to crash or restart. (3) working load of the CPU is dynamic, on the current requirement is dynamic, and the dynamic response speed quickly. Request Some of the poor quality power dynamic response for a long time, could also lead to crash or frequent restart. (4) high-end graphics update equipment (large disk/video card/equipment (increased), after the hard disk) / burners, power supply of original beyond rated output power will cause the regular crash or restart. Solution: now in high quality high-power computer power. 2.The memory chip thermal stability, incorrect or damage to restart the system memory problems to restart the system of risk. (1) the poor thermal stability of memory, boot can work normally, when the memory to a certain temperature, temperature is can not work normally, which leads to crash or restart. (2) memory chips, slightly damaged, also can pass on self into the system, when the operation can be some big software throughput will restart or crash. Solution: replace memory. (3) memory of CAS value too small can also lead to instability caused by system memory, automatic restart. General had better use the default Settings, don't roll change yourself. 4.The CPU temperature exorbitant or the cache damage (1) the CPU temperature exorbitant often causes protective automatic restart. The basic reason of high temperature is due to poor cooling chassis, CPU, the CPU is undesirable reasons: the heat radiator thermal conductivity low, radiator material with a foreign body between CPU interface (1) for quality assurance, fan speed is low, the fan and radiator dust too much, etc. And P2, P3 motherboard CPU temperature probe damaged under the mp4 or within the CPU temperature detection circuit on the mainboard damage, the BIOS BUG in a special conditions of temperature, the CPU CMOS setup to protect low temperature, etc. Can also cause protective restart. (2) of an internal CPU, level 2 cache damage is CPU common fault. The extent of damage, or can start, when running into the system, the software (some throughput big media player, games, 3D graphic) will restart or crash. Solution: in the CMOS setup of shield (L2) or level 2 cache cache (L1), 1 or replace the CPU. 4.AGP display, PCI CARDS (nics), cat restart automatically (1) the external card or poor quality work not standard, AGP/PCI bus signal misoperation cause system RESET to restart. (2) and graphics, loose network system may cause restart. 5.Parallel, USB access is serial, fault or the incompatibility of external devices restart automatically (1) the fault or not compatible with the parallel damage, such as printer, a foot of short-circuit, USB equipment damage of short circuit, signal level sutural definition, opaque, etc. (2) hot swaps external devices, shaking, cause signals or power instant short-circuit. 6.Mainboard failure In case of automatic restart motherboard is rare. Generally RESET circuit are associated with a fault, Socket weld is empty, slots, contact undesirable, Individual chip, capacitance elements such as damage.

Heat problem?


Okay you can check if its overclocked in the bios under advance cpu settings. But 9 times out of ten here if your cpu did overheat and got hot enough you may have damaged it.

1. Try another cpu if that works replace
2. try the cpu in another motherboard if that works replace the main board as it could have gotten hot enought to damage the north gate.

I am sure the if you got errors well after compuding it you do have a overheated cpu and replacing it would shore this up dramatically.

I bid you good luck with your computer please do rate the solutions.

Problem with intel d101ggc motherboard


Hi Rohit, you're CPU should not be running that hot & that is why you're system is restarting. Very soon the CPU will burn up.
Replace the CPU's HeatSink & fan assembly as soon as possible. The link I have posted is a list of the CPU's you're board can support.
http://www.intel.com/support/motherboards/desktop/d101ggc/sb/CS-025906.htm
Even at 70'c, that's too hot also. You're game is not putting that kind of load on you're CPU.
