XPS 730 turns on but only fans work

[geoman55]

I have an XPS 730 I bought in 08 it is a 3.2 quad core 4g ram dual video card. It powers on with fans running hard but no beeps no post no bios never makes it to the dell load screen. Did it once before and I unplugged it and waited about a minute and replugged it and it worked, but now when I replugged it the computer turns on without touching the power button and the power button when it is turned off stays blinking with one long blink and when it is turned on the motherboard reads 02 or 20 depending how you look at it what does this mean time for a new computer?

This happened to my PC and it was a broken motherboard.
