4-LED lights...boot/post problems....

[Vito117]

I'm re-building my spare DFI Ultra-D rig for my mom to use

Installed a Sempron 3000+1 Gb G-skill

When I do a new build I like to do a bare bones boot. ( CPU, video card and thats it) All mobo power connectors are in.

 

Well I cleared the CMOS, and was able to boot up, got into the BIOS and made the usual changes.

Then on re-boot.....nothing.

Only cpu and case fans spinning, no post beep, and the 4 LED lights all lit up.

Cleared CMOS again...pulled out battery..wait 30 minutes.

Same result.

Ran to Best Buy.....Installed brand new Antec 500W ps..... Same results.

 

Is this mobo dead?:mad:

I did notice that when I was handling the mobo it seemed to have a greasy film on the underside. What the hell would that be?

 

Any ideas?

If you haven't done so, I would change all of the settings in the BIOS to Optimized Defaults.

 

The four LED's denote "System start-up". Three LED's would denote CPU detected. So, check your CPU to assure that it is installed correctly, also.

 

I can't tell you what the greasy film is, unless it is out of a capacitor.

If the rig has been in a room that people "smoke" in, then it could be a candidate.

This morning I re-installed the cpu + heatsink. Then cleared CMOS.

Powered it back up and I still get the same results.:confused:

 

On initial first boot I get the post beep , boot screen shows the cpu correctly...memory etc........then into the BIOS I went.

I set it to "optimized" and upon reboot.......blammo...back to 4-LED's and all fans running at max speed......and a blank screen.:mad::mad::mad:

 

As far as the greasy stuff....I wonder if its not a capacitor?

Rig was never in a smoked filled room or house.

Hello,

 

Where did you get the Sempron 939 CPU?

This was never released to retailers and only some OEM builders like HP had some in their PCs.

 

Could be why it is not quite working.

Clear CMOS again

 

When you enter the BIOS

- Set the LDT ratio to x5

- Set the CPU Ratio to x9

- Set the Vcore (startup) to 1.35v

- Memory in the orange slots.

- Disable CPC

 

And see what happens when you save and exit.

 

Also what bios version are you using?

I tired as you listed above to no avail

Using latest BIOS from the DFI site. 4/2006

DFI website says the Sempron is supported right?

I mean the cpu boots ....everything looks as it should...it's just that it wont hold the CMOS or something?

What happens if just one memory module is in the top yellow slot?

 

Instead of clearing the CMOS, hold the insert key down and press the reset button.

Keeping the insert key held down, wait.

And see if it posts.

 

Does the board still work with the other CPU?

Tried what you said.....nada

 

It's weird since I had this rig running smooth as glass with an Opty 170 for over a year.

I have to think it may be this g-damn Sempron.

I just bought a s939 A64 3400 Newcastle off fleabay. So I can test it with that one to see what the hell's going on.

 

Thanks for the help!

[Sharp]

Let us know the outcome.

[Vito117]

Well.....I'm back.

Bad news.:confused:

 

I'm getting the same results when I popped in a A64 3400+. No post after corrections made in BIOS like before.

screen.

So I tried both cpu's on ANOTHER Ultra-D mobo I borrowed from a friend....same freakin results.

 

I then popped both the Sempron and the A64 3400+ into a Asus A8N5X along with the GSkill sticks and both cpu's posted perfectly and was able to adjust settings in BIOS and save....reposted and back in I was able to go.

 

So do I have not one but TWO bad Ultra-D's???? Come on...you gotta be shitting me here Pyle!

 

Out of ideas here.

[Vito117]

Case closed......these Ultra-D boards suck the big one.

I'm moving on.

DFI lost a customer. If they produce a product that basically equates to spinning a freaking roulette wheel in Vegas then no thanks.

 

No mas, no mas.:mad:

Before you toss it in the bin, try it again with another psu.
