Why does my PC just shutdown itself-how to fix it in minutes

Computers should not turn themselves off without a good reason. Oftentimes, when a computer does shutdown, it does have a valid reason - such as if the computer is protecting itself from danger (most often heat). Other reasons for random shutdowns are not for self-preservation but as a symptom of something else, such as a loose power connection or failing memory chips.

Heat and Dust

Your computer is put through the paces, day in and day out. It gets hot. And it's often one of the most neglected pieces of equipment on your desk as far as cleaning and maintenance go. When a computer's CPU gets too hot, it may be set to automatically shutdown in order to protect itself from damage.

To troubleshoot and clean an overheating computer, you'll need to power down the PC, unplug it from the power source, ground yourself, and open the computer case. It's dirty in there, isn't it? Use a can of compressed air to gently blow the dust away.

Power Connections

While you have the computer case open, inspect the fans along with the power supply connections. Is the power supply's connection to the motherboard properly connected? Does everything look okay? Later, once the computer is reassembled, you will check the power cord to be sure that it is firmly connected to the PC - make sure to wait until after you've reassembled your computer.

Failing RAM

Check the memory chips. Are they properly seated? Consider removing one chip and running the system on the other to rule out faulty RAM. Then swap chips and run the computer. If the PC doesn't shutdown when one chip is removed, it's a safe guess that the removed RAM is faulty and needs to be replaced.

Once you're swapping RAM chips, reassemble your computer and place it in an area where air can flow freely around its vents.

Computer Viruses and Malware

Computer viruses and malware may be to blame as well. These nasty little programs run without your knowledge, putting your computer under pressure to carry out more tasks than you can imagine. These tasks hog memory and cause the computer to work hard, thus contributing to the overheating problem. Run a complete system scan for viruses and spyware to rule this out as a possibility.
