Re: Computer shuts down after being on it after a while.
You are probably right. It a cooling issue. it usually happens when your heatsink gets clogged with dust or the coolant fan stops running. I have installed a softare called speed fan which automatically adjusts the fan speed according to the temperature. It will atleast resolve this issue to some extent. Also you are advised to clean the interiors of your PC with a non-static brush or duster(Dont use the normal paint brushes or a dust cloth. The static electricity can damage your chips). If nothing resolves this issue then you are probably looking at a change of heatsink.

computer probably reaches its safeguard temperature. and shuts the system down to protect it from damage. usually it is caused by a partially/fully clogged heatsink on either the processor or the graphics card (or both). and insufficciant air circulation trough the case. if so you have to clean the fans and heatsinks (a box of compressed air will suffice if its a laptop, put something in the fan to prevent it from spinning while using compressed air), dont forget to do the chassis fan too (if its a stationary one)
it may also be that the heat sink is not making proper contact on the prosessor/ graphics card. you may need to reseat it with new thermal compound
It is overheating. It may be a few things, check the vents and make sure they are not blocked by anything (sometimes dust can block them as well). Also listen and feel at the vents to make sure you fell air blowing out (if not the fans may have died out).
The fact that it shut down means it is trying to save the components before they burn out. You should be able to turn it back on once it cools down enough. You can also use a fan to blow air through the vents to speed the process. If it continues to shut down, it will burn out eventually if not repaired. You can get by for a while by using a fan base (you sit the laptop on it and it has fans blowing air on it to keep it cool). You can purchase this at any bestbuy or staples.
First test your CPU then tast all leads that are attached to your hard drive sounds like a faulty lead of some sorts then try replacing all the leads that attach to your hard drive including electrical extensions + IDE,SATA and the ones that attach from your motherboard to hard drive make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty or just replace them they are probably old and faulty ? good luck
The fans themselves may need to be replaced or the thermal grease on the processor may need to be reapplied. What you are describing is caused by something getting to hot and then shutting the machine down to prevent damage.
Your computer is automatically shutting down to prevent damage to the CPU because it is getting too hot. This can be caused due to a malfunction fan, heatsink, or dirt inside the CPU.
Remove the side cover of the CPU. Using a can of air (which can be purchased at most electronics departments), blow out any dust inside the case, paying specific attention to the fan and the heatsink mounting the CPU. Also blow out all vents and anywhere else you see dust. Do not shake the can of air and keep it as level as possible. If you do not have a can of air available, an air compressor will work. Alternatively, you may vacuum the dust up with the hose of a vacuum cleaner but do not use any attachment with brushes on it.
If the inside is relatively dust free, check to make sure all the fans are functioning properly. If the one on the CPU is not, then that fan will have to be replaced.
And one more thing, please give this solution a fixya rating. Thanks! :c)
your files might have been corrupted i know the end close screen file sometimes and will get corrupted quicker than startup screen
now the question is was this the floor model or a straight out of the box unopened comp cause floor models always needs to be reformated those are the show comps. people play with those all day once you reform. comp. and put in new O.s. system everything should come back to working perfectly and dont forget spyware checkers and virus blockers name branded backed up these will help protect your comp
simple other solution might be you just need to upgrade your system files threw windows update
Hi James, replace the fan or If it's still under warranty have it serviced. Suggest you stop turning it on until the fan is replaced. It could be the fan cooling the CPU. You don't want it to fry.
The shut down process is normal when over heating is detected by the system.
