Do you have the latest bios? A new one was released last week.

lol...I dont know what the bios would have to do anything but nice suggestion....

[b:1f99818d52]Unimatrix-Zero[/b:1f99818d52] funny that your going through this as I went through this last week. My first board (amd) had had but loads of promblems. Now let me just say that everythign i had also was brandnew. I found the folowing things wrong...

1. The power pins on the motherboard werent on right

2. Powersupply was bad

3. Floppy was bad

4. Ram was in wrong dim

Now keep in mind again everything was brand new. maybe you might try to test the power supply with a volt reader? and make sure all your connections are in right. Are you getting any beeps on a boot up?

[b:a4bab39e83]Reverend[/b:a4bab39e83]- Ive have actually installed the latest bios from the shuttle site...thanks for the suggestion:D

[b:a4bab39e83]XPerties[/b:a4bab39e83] - Could be right with the Power supply, tried about everything else even different ram.....actually running a P4 power supply in it - though I wouldnt think that would matter.....but ur right I will have to check the voltage!!!

Floppys working so I dont think its that, and Ive double checked the power pins and there all in the right connectors

the DDR slots actually have an LED display which lets u know if there installed properly and thats lighting up

No system beeps either at bootup

[b:36d8840cc7]unimatrix-zero[/b:36d8840cc7] Have you tried a different psu.Here's a list of compatible and non compatible psu's.Taken from Shuttle site FAQ'S;

----------------------------------------------

Q7 Which power supply is recommended in conjunction with AK31 series mainboards?

A7 It is advised to choose power supplies from AMD Athlon Processor Recommended Power Supplies as listed on the AMD website.

Apart from that, the following table is gathered from comments from users regarding mainboard power up issue Vs. power supply used on AK31 :

Working PSU

Powerman 300W

Enermax 330W

Sparkle 300

Antec SX840 w/412

Antec 300W

Antec 400W

Antec 1030 case (and 300W PSU)

It is recommended to avoid using the above not working power supply unit.

:eek:[b:36d8840cc7]XPerties[/b:36d8840cc7] I mentioned the bios because it may not have fully supported the hardware.There is a method in my madness

TAKE A LOOK AT THE SWITCH!

though the other posters ideas are just as good.

[zErO]

Found the prob:D ....its the atx connector, seems one of the the wires from the actual plug was a little loose and was only partially connected......ran a voltage reader to check the output of each connection and found a dead one:cool:

thanks for the input guys:D

[Big Booger]

Smoking, got the voltometer, and pinpointed it eh??? Smashing good show old fellow.

Somthing very similar happens to me..and i have never been able to figure it out. Sometimes when i shut my computer down and leave it off for a while(over nite). When i hit the switch the computer starts up, but my moniter will stay in suspend mode. To fix this i just hit the power switch in the back off and on then i start it up again and then the moniter starts with the system. I have no idea why this happens.

Things I would check for that drew,

1. Your graphics card might be the culprit

2. Check DPMS (Display Power Management Signaling) matches video monitors and video cards so they may simultaneously shut down or startup.

It seems to be a power management issue, though I have no experience with this, as its strange.

By the way do you have on board graphics? if so, make sure it is disabled, or unistalled.

This one is for Drewdatrip.....

I had the exactly same problem with my computer and had to turn off and on again the power suply switch......

I thought the problem was the graphic card and bought a new one, but the problem was the same....until one time the computer didn´t start at all......well, I found out that the problem was the motherboard...and had to buy a new one......I know thid doesn´t help....but sometimes the truth is not what we´d like t hear......:blueteam
