Ultra-D Problems

Recommended Posts

When I first got the DFI Ultra-D, I had the problem of getting to "Windows is inspecting your hardware" and the machine would no longer move along. I solved that be resetting the BIOS and taking out the battery.

Now, I am experiencing a new problem. I have my machine on most of the time 24/7, recently I turned it off for one night of good rest. Woke up next morning and the machine would no longer boot, the LED light display on the motherboard shows three lights on, which means its stuck at detecting the CPU.........

Nevertheless I took out the board from the case and connected everything and it came back ALIVE!!!!

Last night I turn it off and it happened again (it wont boot), just wondering if anyone knows this to be a BIOS problem?

 

Any help is appreciated

you need to make a sig with all components that you have. please be specific. every component is essential for us determining the problem. not making a sig is like telling a blind man to tell us the time

Configuration:

DFI Ultra-D (Initial BIOS), 2 x 512MB DDR 466 Kingston, 2 x 160GB WD (Raid 0), Cooler Master 450W PS, Prolink 6600GT, AMD64 - 3200, water cooled CPU (Swiftech 6002A) & VGA (Swiftech MCW50 )

 

I have tested tested the memory, CPU, video card and the power supply and they all work fine..............

It is not overclocked at the moment

 

Its only the second time this has happened but it is quite annoying..............

Here is the way to read the Diagnostic LEDs.

 

4 LEDs on = Power applied, checking CPU

3 LEDs on = CPU has been detected OK, checking RAM

2 LEDs on = RAM has been detected OK, checking VGA

1 LED on = VGA has been detected OK, entering BIOS

0 LEDs on = System has booted to the Operating System.

 

As long as you are in the BIOS including running memtest from the BIOS option, there will be one LED on.

 

Example: If you are getting 3 LEDs on, it means the rig is having trouble detecting the RAM.

 

The lower(PCI) Amber LED is the 5VSB indicator. The upper Amber LED is the RAM voltage indicator. Once the rig has started and been shut down the RAM LED will go out until the PSU is power cycled.

Yeah, 24 pins and the molex plug around the chipset fan is plugged in as well.

The machine has been running since Feb. this year and this is the second time this has happened................so I'm not sure what's wrong with it as everything seems to be in order.

 

Will have to try the BIOS reset and battery out thing again tonight when I get home.

Meanwhile, if there are other things I should try, please let me know......

I notice there are a few users who have got problems starting up their machines as well although they dont all have the same symptoms as my.............

Problem solved..............

It wasnt anything technical, not computer wise anyway........

I took the board out of the case and it worked fine, put it back into the case and it refused to boot.

In the back of my mind, I rememeber a tech support mentioning somethin about having the screws on too tight or too loose causing start up problems..................

So I loosen the screws on the board a little and what do you know..................its ALIVE!!!!!

Not sure if this applies to all the other "cold boot" problem users out there, but whats the harm in trying by loosening the screws a little or tightening it for that matter............................. :)

If anyone knows the theory behind all this (guess its got something to do with the circuits), I am all ears!! !!

Take that thing apart and measure the standoffs on the motherboard tray to make sure they are all the same height. I got a system in my shop from a customer that had bought it from a local PC shop. That thing had three different length standoffs on the mobo tray. Once they were replaced with the right size, it never rebooted on her again.

 

Fans and fan controllers can cause all kinds of weird problems just like anything else you plug into the PSU.

 

Don't forget that even the best and most reliable PSU can fail without warning.
