I love a challenge...
Could you please clarify something first:
I'm not sure what you mean by 'bios power'. When you attempt to power the computer on normally, what exactly happens?
i.e:
1) is there any power at all to the system?
2) Does the monitor LED change from amber to green, and if so, do you get a display on the monitor?
3) Do you hear any beeps?
4) Do the keyboard lights (Caps lock etc) flash once just after powering on the system?
Secondly, can you please tell us exactly what motherboard you have (brand name & model number), what cpu & memory you have (as much detail as possible please), and what video card & hard drives you have please?
Also, what PSU do you have (brand name & power rating in watts)

0.<There is a button on the motherboard that you can hit that says bios reset>
1.yes only when i hit the bios reset
2. no monitor hasnt hit green since the day it died
3. Fan goes everything goes i dont think any beeps but its louder then normal
4. I remeber before the mouse lights turned on but i can quite remember
ive also tried a new monior and no luck
thanks a lot for helping me btw because im getting frusturated

The mouse light doesn't really mean anything other than there's power to the motherboard. Could you check the keyboard lights as well please?
Am I right in thinking then that if you try to power the system on normally, using the power button on the front of the case instead of pressing the bios reset, you get no power whatsoever to the board? i.e no fans etc
NB Don't forget to provide the rest of the info I originally asked for!

1) Disconnect the wires from the front panel header on your motherboard (i.e the power & reset switch wires, HDD LED, power LED etc).
2) Make sure the PSU is connected to the motherboard, is plugged & switched on at the back.
3) Next find a small flat head screwdriver.
4) Consult your motherboard manual to check which 2 pins on the front panel header are for the power switch. (Don't assume you already know - double check!).
I have been trying to look this info up myself for you but DFI seem to have managed to have crashed their webserver at the moment...
5) Bridge these 2 pins (i.e touch both at the same time) with the tip of the screwdriver. This should (normally) power the board on. Let me know if it does & what happens.

According to the manual, the onboard reset/power buttons you have been using do not clear the bios. You need to use the jumper cap to clear the bios.
The soft power pins I was referring to before, are the 2 marked 'ATX-SW' on page 44 of the manual.
Are you now able to turn it on by touching these 2 pins together or does it still only power on when you press the reset button?
According to the manual again (see page 15) you should have 2 buttons - reset & power. Does pressing the power button turn the system on as well?
Are you saying that approx 8 seconds after powering it on, it shuts off again by itself?
The fact that you can't power the system on again straight away is normal for this board. It forces you to wait a few seconds to allow itself to fully discharge first.
Does the LED on the monitor turn green at any point now?
There is an 8 pin power connector on the motherboard near the cpu (see page 41). Your PSU doesn't seem to have an 8 pin 12V connector so have you got the square 4 pin connector connected to this instead?

Can you try the following suggestions please:
1) Firstly, clear the bios. You can use either JP8 on the rear of the motherboard or JP2 in the bottom right corner of the board. Whichever one you choose, make sure you first disconnect the external power lead then unplug the main ATX power connector from the motherboard.
Next move the jumper cap so that it covers pins 2-3. Leave like this for 30 seconds then replace cap so that it covers pins 1-2. (see page 28 in manual if necessary)
2) I assume you have at least 2 memory modules. Can you remove all except one module. Make sure the single remaining module is in the first ram slot. (DIMM 1)
3) Make sure that your video card is securely seated and is in the first PCIE1.
4) Make sure you have the internal case (system) speaker connected. See pages 44 & 45 of manual
5) Check that the cpu FSB is set correctly. This is on the jumper block next to the CPU. Your cpu uses an FSB OF 1333MHZ so it should be set as follows:
JP17: cap must be covering pins 2-3
JP18: cap must be covering pins 2-3
JP19: cap must be covering pins 3-4
6) If you haven't already done so, make sure that all the drives (hard drive/optical drive etc) are disconnected. i.e disconnect the drive cabling from the motherboard & disconnect the power to the drives. Also make sure you have no external devices connected except monitor & keyboard.
Let me know if this makes any difference at all. If not, I suspect the problem may be with either the PSU or the motherboard...
