Hi

the difference on the 1.6Ghz and 1.7Ghz is the processor, so the board should be exactly the same, so yes you can.

If you look up the model details from both boards I can compare.

Not powering up with steady orange power light


Did any one open the system, after which you are facing this problem?
If the 4 pin power connector is disconnected, you will face the same symptom.

This symptom can also appear if you have any external or internal devices electronically failed / Short circuited. Remove any external devices even external hard drive, flash memory devices, camera, printers etc and then restart the computer.

There is also a possibility of flea power, remove the power cable from the tower and press and hold the power button for 10 seconds, this will drain charge from the capacitors from the motherboard.
then connect the power cable and test if your issue is fixed.

if the issue is still not resolved, then we have to remove any internal devices, eg, add on sound card, video card, modem etc and then try powering up, if the issue persists there could be a problem with either the motherboard or power supply, which needs parts to be replaced and tested.

Dell 4400 won't power up Flea light works


For non-BIOS issues:

If you did not try to update BIOS before the problem started then try these troubleshooting steps.

1. Full power down. Unplug the power cord from the Power supply. Then hold down the pc power button (this discharges any residual power in the capacitors).

2. Open the case and reseat the graphics card, hard drive, and RAM.

3. Take out one of the RAM sticks if there is 2 or more. Swap the RAM sticks in different RAM slots. Try one stick at a time to see if you can get the PC to boot. If this works, then the remaining ram sticks are damaged.

4. Set the Cmos jumper to clear. Power up the pc. Power down the PC. Set the Cmos jumper back to normal position, power up the PC.

5. Unplug and replug all the power supply cables.

6. Check the powersupply function. Either by a powersupply voltage checker (20-25 dollars at local PC shop), get the supply tested at a PC shop (usually a free service), put the powersupply in a different pc, or try a different powersupply in the problem computer.

If the Powersupply checks out ok, then you will have to do a process of elimination to find out what part or parts are the culprit of the No-Boot.

Start by pulling all the ram sticks if you have not already. This is the easiest components to check and usually a culprit.

Take out one of the RAM sticks if there is 2 or more. Swap the RAM sticks in different RAM slots. Try one stick at a time to see if you can get the PC to boot. If this works, then the remaining ram sticks are damaged.

If it is not the RAM, you have to continue removing items such as sound cards, un-plugging hard drives and optical drives, other PCI cards. Do this one at a time until you find the culprit. If a POST screen, meaning you can see Anything from the PC brand name to Motherboard brand name appearing on the screen. The PC may not boot to windows, but it Does post at this point, and with that the problem is resolved. If windows does not load, then you have a new problem. Best dealt with asking a new question.

Good luck!
