Question about Dell Dimension C521 PC Desktop
You will have to get your power button unstuck. I do not know what type of button you have but if you would like to at least get your PC on without it instantly turning off, you can remove the power switch connector from the motherboard. You will eventually need to have the switch unstuck, or replaced though.

Testimonial: "It turned out that the power button was stuck. I had everything unplugged from the computer and took the side panel off. The power button connects to a small plastic tube which is a couple inches long and curves upward. The plastic tube goes into a panel, and at the joint where the tube enters the panel the tube was stuck. With the tip of a screw driver I softly pushed the tube back into place and the power button popped out. Thanks for the help."
If it's a Dell computer, the PSU is in safe mode, to fix Dell desktops with power cord out press and hold the power button, then connect the mains power lead, keep the power button held until it shuts-down release the button, now try turning on as normal... Hope that works for you.

Is the Ethernet built-in on the system board? I would go to BIOS (hit F2 while booting the PC) and disable the ethernet. then restart the PC. See if it stays on with or without the Ethernet cable plugged in. If it does. The built-in Ethernet circuit is the problem. I would buy a Ethernet adapter ($20).and install it. and leave the built-in ethernet disabled.
If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.

SOURCE: Computer wont turn on
I had the same problem here. And sure enough it was the USB socket that had been bent inside or broken off. Basically the pins were touching the sides of the casing and causing it to short on power up.
I used the method suggested above - get a screwdriver and (MAKING SURE THE POWER IS OFF) bend the pins from the USB socket back into shape so they are no longer touching the side casing. The USB port is unusable but the machine powered up straight away and is now working fine.
Thanks for your help!!

Try holding down the power for a full minute or two then start it up again. The power button may be set for sleep and not shut down. You may have to hold the button longer. If that doesn't work it could be RAM, or a serious problem with the motherboard.

It's likely that your power supply has started to go out. There are several different leads with varying voltages & amps. If your computer is getting enough power to make a light flash yellow or orange then this often means that there is something wrong with one or more of the voltages from the power supply. Sometimes it means that something is wrong with your motherboard. Like: burned out capacitors, resistors, & etc.
