I'm an IT Manager with 20 years experience. First, I can't see on the mobo where to hook up the speaker to check diagnostic beeps. Second, it flat out died tonight, I'm using an Ultra case..don't know the model number of the case. I've been running Windows 7 beta for a little while, walked away, and the damn thing powered down abruptly.
I've pulled all the cables, re-seated the memory and CPU, but all I get is a quick red flash on the power light when I push the power button. I tried another power supply (assuming this one had died) same reaction. Can someone either point out the PC Speaker hookup for me on the 6100SM, or if you know what a quick red LED flash is upon power-up, that would be great. I assume something died, but the manual is sparse, and so is Google Search.

Re: No activity whatsoever
Hi there on the board there is a speakers socket( 2 or 3 pins) near the power connections for front switching,try booting with no ram after you get a speaker connected or piezo buzzer,change out ram if you can

You have the speakers plugged into the 'green'-colored sound connectors at the back of the mobo.
Also make sure that your 'Windows Sounds' aren't set low. Sometimes I set my Sound Properties (accessible when you double-click the speaker icon in the taskbar) to 'lose' that setting, to keep things simple. But if your overall volume is at 100%, and this setting is at around 20% or below, you could experience this issue.
If these are not powered speakers, you know what I'm saying here...
I'll check back in later to see if this helped you.
This is very difficult to troubleshoot because there are too many unknowns.
Does the mobo have diagnostic LEDs? The changes in indicators would indicate the boot up activity is taking place. If you have no visual indicators, then
You might have to get a boot up code display. This is a device that connects to the bus (via pci / pcie slot in most cases) and has a digital readout. When the mobo stops on a certain code, you will have to lookup the code to determine where it's getting stuck.
If you have no access to a diagnostic card, then some of the other very "elementary" things you can do are:
Listen for the beep code. If the speaker doesn't beep at all, then your CPU is likely not running the POST test. Check your power on LED. Check your HDD LED to see if any disk activity (hdd detection) takes place.
Other than that, you're SOL without some equipment.
The spray on the MB should not be a problem - unless it was plugged in when you did it. Yes, you should be able to put in a new Dell motherboard. As long as the processor is of the same class, the Dell license should work fine. However, you may need to download new drivers for the machine to run.
If you really want to check the power supply, I would suggest you buy a tester. They are fairly cheap: $10-50. You want to be sure that your board is getting the right power at the right places. 12 V to the fan is fine. However, 3.3 v or 1.5 v?
It sounds like you have done a fairly good test of the motherboard. I've definitely seen bad Dell motherboards with the light on with/without a bad power supply.
If you have another case (an ATX), I would buy an Asus or other motherboard and put your equipment in it. The cost of a Dell motherboard is excessive. Of course, you will have license problems with XP.
Front Panel Connector
The front panel header is where the connectors of hard disk drive activity lights, case speaker, reset button, power on/off button, computer power on light, and key lock, are connected to make them function smoothly. In the past days, users always have difficulty connecting the front panel due to a lack of standard location on the motherboard. Today, AOpen integrated all these disorder but essential front panel connectors into one 20-pin connector for easy usage. Connecting the front panel would no longer be the headache of installing motherboard anymore. Below is a view of this user-friendly front panel connector of AOpen motherboard.
Go to Add/Remove Programs and uninstall the software related to your soundcard.
Go to Device Manager and remove the sound card it is the device that has an exclamation point or question mark.
Turn off your PC and remove the Card. Then turn it back on again and enter the BIOS setup and disable the built in sound card of your motherboard then press F10 and save the changes.
Restart your computer and verify that windows is not going to scan for missing devices. Check the Device Manager again and look for any devices that has an exclamation point or question mark. If there is none. Turn off your computer put the sound card back in and turn it on again. Put in the CD Driver but exit on the autorun let windows detect the card automatically and wait for it to ask for the location of the drivers. Point or browse to the driver location and let the installation finish and click on ok. Your PC may ask for another restart do that turn on your speaker and listen for the boot up sound if your hear it then your card is now working.
Same configuration? (Same: Mobo, Processor, Hard Drive?) Just new case and cables? Do you have onboard sound, are you running a sound card, or perhaps you're plugged into a fancy graphics card sound port?. Try these configuration tips before you tear it all apart: Check your device manager in the system section and make sure your intended sound device is operational with no (!), or (?) alerts next to it. Reinstall any mobo, graphics card, or sound card drivers which run your sound device. AND finally, if you have more than one sound device on your computer (mine has all 3 options I described), make SURE you have the right one selected in your sound manager!
Is the case speaker connected to the motherboard?
If it is, do you get any beep sequence? If there is no display, the power speaker output an audible beeps sequence. For example, 3 short beeps mean a problem with memory.
