Re: how to keep the speaker pins to motherboard

For that purpose you need the manual of the Motherboard if you dont have it download for the manufacturer site of the board in the support or download section.

How to connect reset power and leds

Okay, look at your motherboard from this orientation so we're both looking at the same thing in the same way.


On the bottom of the motherboard, just above and to the right of the notation "MADE IN CHINA", is a group of pins with the notation above that reads "PANEL 1". That's where your Power switch, Reset Switch and LED lines will plug into.
Look at the eight pins in the nine pin panel that form a box of two rows of four pins each. Those are the actual pins you'll be using. Ignore the one on the bottom row that's off by itself. Shuttle does, so we should as well.
Now, to the right and down of PANEL 1 is a little drawing on the motherboard of PANEL 1 with little lines and numbers and such. This little drawing shows you which pins are used for which lines. It looks kind of like this...
2 4 6 8
'MSG ' PWR '
'LED ' BTN '
'HDD ' RST '
'LED ' '
1 3 5 7
Lastly, as PANEL 1 has a little "+" right next to Pin #2, and we don't have a manual handy because Shuttle seems to have all the information available on the web except a copy of the bloody manual, we're going to take an educated guess that for each two-pin part of the box, when plugging in the individual plugs, make sure the black wire is the one on the right, and the colored ones will be on the left.
So, plug the Power button into the upper-right two pins, black wire on the right, Reset on the lower-right, HDD LED on the lower-left and the Power LED on the upper-left. (I'm guessing that's what "MSG LED" means. There are no "Power LED" pins anywhere that I could find.
This should take you only a couple of minutes, so post back if you have any difficulty. If you need a hi-res image of this motherboard, go to the below link.

6 beeps what dose it means

Dell beep codes:

If your computer beeps during start-up:
Run Dell Diagnostics to identify a more serious cause.

Beep Codes Your computer might emit a series of beeps during start-up if the monitor cannot display errors or problems. This series of beeps, called a beep code, identifies a problem. One possible beep code (code 1-3-1) consists of one beep, a burst of three beeps, and then one beep. This beep code tells you that the computer encountered a memory problem.
If your computer beeps during start-up:
Dell Diagnostics to identify a more serious cause.

How to install amd 64 mother board cd

install the flat cables coming from the hard disk drive, optical units and floppy disk drive. If you didn't install these devices to the case yet now it is a good time to do so. The cable from the hard disk drive must be installed on the IDE1 (primary) port and the cable from the optical unit must be installed on the IDE2 (secondary) port. The floppy cable should be installed on the floppy port. To install the cable, just pay attention on the red wire, it should be installed facing the "pin 1" marking on the motherboard. This marking is usually a number "1" or "2" painted on one of the sides of the connector (the opposite side should be marked "40" or "39", or "33" or "34" in the case of the floppy port).


Figure 19: Cables from the hard disk drive, optical unit and floppy disk drive correctly installed.
The next step is connecting the power supply. The power supply has one 20-pin connector and your motherboard can have an extra 4-pin connector called ATX12V, which should also be installed (not all motherboards have this extra connector). You may need to lift the motherboard in a 45º angle with the table you are using to assemble your PC, since usually the wires from the power supply aren't long enough to reach the motherboard while it is on the table outside the case.

How to reset the CMOS

I need the motherboard model to know the exact location of the jumper you need, but this is what you do. Usually on either the bottom or top right hand side of the motherboard there is a 3 pin jumper with a plastic plug on 2 of the pins. You need to SHUT OFF the computer and move the plastic plug to the other side of the 3 pins for approx 10 seconds, then put it back on the original 2 pins. That will reset you CMOS memory.

There are 3 pins O O O

The jumper is on 2 of them O X X

Move it to the other side X X O

Then return to original O X X

I can provide more info if you can tell me the maker and model of your motherboard or the model of your computer.

I hope this helps.

Dell dimension 9200 series desktop does not start

Most DELL's I have seen with this condition it was either the motherboard or Power supply. If your mobo looks fine (see explanation below) then I would try another power supply first. Use one that has the same or greater output watts. I keep several old ones around for this purpose. If that does not solve it then you may have a failed motherboard. Failure of motherboards is usually due to breaking capacitors. A few years ago a capacitor company stole the "recipe" for making capacitors from another company and tried to make their own, unfortunately they did not get the ingredients right and the capacitors started breaking after 2-3 years of use. They sold these capacitors at very cheap prices and a lot of computer companies and power supply makers bought them. This is easy to diagnose. Look for capacitors (caps) (they look like little tiny soda cans) on your motherboard (mobo). They should be perfectly flat on top and not bulged or swelling or leaking anything. Be sure to look under the fan shroud also. The dead giveaway will be the fact that you are not getting anything after you change the PSU. There are a few companies that will repair broken capacitor issues. Also if you add a bunch of extra components without upgrading the power supply you can suffer underpowered situations and that can cause internal parts to fail. To eliminate some other stuff you could remove the memory and disconnect all the power plugs from the drives and then try to start it up. If it does not change the behavior at all (no beeps, no change in flashing lights) then you probably have motherboard issues. Make sure when disconnecting the memory chips (sticks) that you touch the metal on the inside of the case first to discharge static electricity. If it does change the behavior add 1 component or item back at a time to see what you can find out. Post back with what you find. And remember a bad PSU does not always mean no power, just not enough to run the computer. I disagree with the post by GUEST. If you are having Hard drive issues the amber light will not sit and blink at you. I don't know how many DELL's they have worked on, but most DELL's I fixed had 1 of those 2 problems. If mobo looks good then try a bigger (more output watts) power supply. If you have the 4 tiny A-B-C-D Diagnostic lights on the back, what state are they in (amber/green/off)? This may help us diagnose further.

Hi infofreak,
Try to follow these steps one by one.
1. Remove the power supply cable from the hard disk, CD/DVD, floppy drive or any other device you might have.
2. Check the wires that go to your front panel ;pwr sw, reset, hdd led, pwr led, speaker etc. Make sure there are at the correct position.
3. Now turn on your computer, if ok you should see some info on your monitor screen.
4. If ok, you can put back the power cable to hard disk only left the others open. Turn on the computer , if ok then proceed with other device one by one. If something wrong in between then maybe your power supply isn't deliver enough power to your system. Get a larger rating power supply.
5. If step 3 is not ok, then take out the power cable on the motherboard from the power supply. Wait a few seconf and place it back to the connector. Make sure it is securely fit, you should hear a click sound once it is fitted in. Turn on your computer.
If Ok repeat step 4.
6. If still not ok, as step 5 this time take out the CPU.

Try the above steps and see whether they can solve your problem. Good Luck

To upgrade from pentium 3 to P4 you have to change alot of the hardware.

You need a NEW P4 Socket mPGA 475 Motherboard.
New 478 PIN Processor.

You can use the old CD rom and Hard drive and any other PCI card but You Need the Mentioned Hardware to Upgarde.
