My computer keeps shutting off, what is causing this?

It is either your computer is getting hot or not enough power is being sent to your computer by the power supply.

Check your temperatures. Check your case fans if they are still doing fine. Intake and exhaust fans should be working. Check the CPU fan. Maybe you need a new one or its to dirty. Check your hard drive maybe its too hot when turned on. Check every hardware.

Try disconnecting some of your equipment such as dvd drive, and try to turn it on. If your computer is still turning off, try disconnecting more equipment which are not essential. But when your computer does not anymore turn off then it means that you do not have enough power being sent by your power supply so buy a new one.

people may tell you it's virus (doubtful), motherboard (possible), power supply or a bad card but if you have a desktop computer with a soft touch power button, chances are that there's a problem with the switch itself that there are times that it contacts the pins from inside the switch. if you have experience with electronics and computers, opening up the case and isolating the problem to the switch might do the trick since it's the troubleshooting step that's less the hassle than anything else hardware-related. So , how do you test? Before testing the switch, turn on your pc and go to the bios by press and tapping F2 or DEL on the keyboard as soon as you pressed to power button. Leave it in the bios for as long as you want to test it. If it doesnt shuts off, then it might be Windows related. But if it does shut off then do this. Open up the computer case. Turn on the computer while the case is open, as soon as it turns on, pull out the cable that connects the power switch from the board then leave it on for as long as you want to test it. If the PC still shuts off, then you may have to isolate by removing all cards (modem, sound card, etc etc) until you pinpoint the problem. Again, you can only do this if you have experience with computer hardware/electronics.. If none, then DO NOT attempt to do so coz you might hurt yourself or even damage the computer.

could be a virus or poor air circulation. try cleaning the inside out as dust has prob accumulated on the parts such as the heat sink (huge hunk of metal with a fan on it) which can cause it not to cool as well which makes it over heat and shut off. but it could vary well be that your hardware motherboard , cpu , videocard ,etc could be going bad. i had a computer with a dieing motherboard with this problem. switched out the motherboard and problem solved

Poor air circulation through the fan could be a possiblity, but it sounds like the power supply is going bad.
