What happens when a computer keeps rebooting?

Question

For the last couple of months, this computer has begun to all of a sudden shut down by itself. The computer light is still on, but there is no signal going to the monitor. We have replaced the monitor, the cords to the monitor, the video card and the power strip. I have also noticed that although the power light is on in the computer, the red light that shows that the computer is running is not when this happens. Sometimes, when restarting the computer to try to get it to run again, this red light does not go on and it does not come back on. Multiple attempts have to be made and you never know when the computer is going to shut down again. There are no power savers active and no automatic shut downs set on the computer. This is so confusing, what should I do next? Thank you in advance for your help.

This is a sign of a power failer in your system, if a red light appears then this is a power supply problem, I suggest to replace the Power supply, if you have a lots of devices attach to your computer such PC card , PCI cards, USB hub Then you should buy a power supply with high watts capacity.

There was a need to replace the monitor if you see the monitor with a orange light beside the power switch.
