Board not powering up correctly

[RoccatJumper]

I have a board that i want to use again but this problem has been stuck with me for a long time now. Whenever i push the power button everything will light up and then shut back down almost instantly with no display at all. The board is a Gigabyte GA-P55A-UD3 and the cpu is an intel core i3 530. I've tried swapping memory in different configurations and putting new ones in there and still nothing and it doesn't stay on for even half a second and no beep codes from the internal speaker.

No i am not sure how to reset the bios. My gpu is a sapphire radeon hd 6950 and my power supply is an antec basiq bp500u.

your motherboard manual shoul detail how to reset bios, but the 100% works every time method is turn off powersupply (or unplug if there is no power button on the PSU), then remove the battery on your motherboard (the thing that looks like a shiny coin) and hold down the power button for 30-60 seconds or atleast 5-10 seconds after all lights have turned off, then reinsert battery and turn on (plug back in) the PSU and start your computer..

how old is your build? psu? does it start without the gpu connected?

I unplugged the battery held the power button for 10 seconds to drain any leftover juice it may have still had in there and put everything back in and it still keeps doing its problem. I even looked in the manual and placed a jumper on the clear cmos pins and waited for a minute then took off the cap and pressed the power button and same result still :/. I had bought the board not that long ago in mid june. The psu i have had it since late 2009 but it hasn't had any sort of issues at all. And with or without the gpu installed it will still keep doing the same thing even after double checking my connectors if they were seated correctly.
