I think my PC is overheating?

Bring it into the shop let them check it out for you.  This will save you monney in the long run if it over heats it can burn up you're hard drive or even go on fire.

You should check the processor temperature. BIOS in modern computers has a setting that shutdown the system when the processor temperature reaches 70 degrees celcius. Think of a better way of cooling your system.

check for viruses (specially when your system booting after connect to internet ) \ncheck power voltage \ncheck  cpu fan \nreinstall win xp \nif cpu fan is good

There may be several reasons why this would happen, I have a laptop and it does this when it heats up. I had a server running in my office which did this because of a bad hard disk. So the bottom line is you'll have to check for all the following: \n\n1. Heating Problem,\n2. Bad HDD,\n3. RAM Issues,\n4. Software Issues,\n5. Viruses.\n\nBy the way if you have done any new upgrades to the HW or software then that might also be a cause for such a problem.\n\nBest regards

It may get overheated or some hardware is broken (it can be a HDD,RAM,Video card etc., I think the HDD has a problem). Try getting a hardware diagnostic tool.

Sounds like your processor is over heating...that will definitely shut down your computer.

The same thing happened to me on my laptop.\n\nIt is possible you are running out of resources.  However the below is what happened to me.\n\nWhat was happening is that the programs you are using are cpu intensive.  This causes the cpu to heat up.  The most likely reason for this is that the fan on your cpu is not making good contact with the cpu itself.  This means that it does not draw off enough heat. When the cpu gets hot enough it will shut the computer down.\n\nYou can get "speedfan" (goggle it) which will tell you how hot your cpu is running.  However unless you know what temperature it will scram (or shutdown) at I don't know how much this will help you.  Basically get someone to reattach the fan.  They need to get some kind of heatsink compound to attach it.

That could be a temperature issue. Make sure the air vents are clean and clear and that your fans are running.

your pc is over heating that is why it is rebooting itslef and in due course it is damaging your software...\n\nIn short u have a hardware problem.\n\nwhat u must do ?\n\n1)check the temperature of your pc.\n2)check your fans.\n\nu must call a hardware expert and must install your OS again.

This sounds like an overheating problem, you did use heatsink compound, right! Did you reinstall O/S after swapping motherboard?

Is the computer getting hotter than usual? Alot of times overheating can cause blue screens and lockups at different times in use. If you let the computer sit for a half an hour, then start it and try to format but it locks up at 30%, then you immediately try again and it only goes to 10%, then I would say that the pc is overheating. If its a desktop, try cleaning it out with compressed air. make sure the fans are functioning properly

As noted before, it appears that you may have an overheating issue.  This is especially likely if your system has been overclocked.  The first thing to check is that there is no dust on the CPU heatsink fins or the chipset heatsink fins.  If there is no dust, then you night consider upgrading the CPU heatsink/fan.  \n\nPrices for these vary, as does performance.  For the highest performance, look for an all-copper cooling system (eitther heatsink/fan or water cooling system).  Heatsink/fan air cooling systems cost as little as $10 for probably about what you have, or as much as $500 for a high-end water cooled case.  Air cooled systems are traditional, and will work for most people most of the time, but water cooling systems will keep the processor (and chipset, if that is part of the system) cooler, which is better for the computer.\n\nYou might also check into RAM coolers, which do the same thing for your memory.\n\nMicroCenter (listed in the sources) has options for all the suggestions I listed above.  NewEgg is also a highly reliable retailer for computer equipment.\n\nUnfortunatetly, if this has happened several times, there may be irreparable damage to the chipset/CPU, and improving the cooling will only delay the failure of the system.

Could be any number of reasons! \n\nPost your PC specs and it will be easier to help you.\n\nAt a guess you might:-\n1. Need more RAM\n2. Need to defrag your harddrive\n3. Your PC may be overheating\n4. You may need to reinstall Windows.\n\nAnd the list goes on and on...

been suffering a similar problem myself, spoke to an IT guy i know, says it may be a power problem, (need new supply) or processor overheating (may need new cooler)?  gonna get him to check mine, hope you get yours sorted, good luck

1) check for ventilation problems; CPUs (the core of your PC system) tend to get a lot of heat.\n2) if you have recently added new hardware (supposing you use Windows) go to "My PC(Right Mouse Click)Properties|Hardware|Device Manager", look for the new device, select its properties (again right button click, then Properties) and Disable it (there's a button just for that).\n\nIf those didn't work, then repost your question but explain you have checked for CPU temperature and new devices.\n\nHave a nice day without computer hangs!

An overheating CPU and or bad ram can do that.

Yeah...sounds like a shutdown virus has been downloaded onto your PC. But before you go that route, have you checked if the fan is running well? At times the fan may not be working so well, which may cause your PC to overheat and shut down. But if you do have a virus, you should just google 'Shutdown virus' and see if there are any anti-virus files available. Good luck!
