This can be caused by a number of things. Here are some of the most common culprits.
Environmental. Have you recently added a space heater, air conditioner, refrigerator, or other heavy-drawing appliances to the same electrical circuit? The system may not be getting enough power, modern systems often have up to 600 watt power supplies, they can be very hungry beasts. To find out if this is your problem, you can try experimenting with plugging your machine into a different household circuit via an extension cord.
Over-taxed. Have you recently added more hardware to the computer? Adding a second hard disk or optical drive, upgrading the video card, or even using some of the power hungrier USB devices can over-tax the power supply of the system and the motherboard will power itself off if it isn't getting the voltages it wants. Additionally, if this is an older system the power supply may just be giving up the ghost, and just hasn't died all the way yet.
CPU overheating. If the CPU heat sink has become un-seated from the CPU it takes about 5 or 10 seconds for the CPU to heat up enough to shut down the system. Double check that the CPU heat sink is firmly attached & that none of the brackets has come loose.
My pet theory (and to be honest im only guessing here) is that one of your fans is having problems.
Most modern motherboards have the ability to monitor the speed of the cooling fans. These systems are often set by default to refuse to stay powered on (they'll shut off after a few seconds) if they detect that one of the fans is not spinning.
Most likely one of the fans in your computer has gotten stuck. Open up the machine and clean them.
Also, if one of these fans comes unplugged, the motherboard will get a 0 RPM reading & will shut itself off. If you've been monkeying around in there, or the machine was just recently assembled, make sure everything got plugged in right.
If you just built the system. It may have hookups for case fans. These hookups may be by default configured to shut the machine down if they dont detect a spinning fan. You may or may not be actually using these hookups for your case fans (you might not even have case fans) and so you would need to go into the BIOS menu and disable case fan monitoring.
