Question about Intel D945PSN Motherboard

Open Question

I have no power button control...........when I push it, it does nothing. The jumper is connected correctly according to the motherboard manual, as well as the case manual. In order to turn the motherboard on, I have to unplug it and remove the CMOS battery for 1 minute. When I plug it back in, the motherboard automatically powers up. Also, the hard drive light and power light stays on constantly with no flashing.

SOURCE: "Reset you're cmos/bios jumper to

HI,
No need to worry. There are many known ways to reset / remove / bypass the password:

  • By removing the CMOS battery
  • By using the motherboard jumper
  • By using MS DOS command
  • By using software
  • By using Backdoor BIOS password
Now I'll try to explain each method one by one:
A. By Removing the CMOS Battery:
xrojer_2.jpg
Almost all motherboards use a small coin sized CMOS battery to store all BIOS settings along with the password. To reset the password, unplug the PC, open the cabinet and remove the CMOS battery for approx. 15-30 minutes and then put it back. It'll reset all BIOS settings as well as the password and you'll need to re-enter all settings.
If it fails, then try to remove the battery for at least one hour.

B. By Using the Motherboard Jumper:
Almost all motherboards contain a jumper that can clear all CMOS settings along with the BIOS password. The location of this jumper varies depending upon the motherboard brand. You should read your motherboard manual to check its location. If you don't have the manual then look for the jumpers near the CMOS battery. Most of the manufacturer label the jumper as CLR, CLEAR, CLEAR CMOS, etc.
When you find the jumper, look carefully. There will be 3 pins and the jumper will be joining the center pin to either left or right pin. What you need to do, is remove the jumper and join the center pin to the opposite pin. e.g. if the jumper joins center pin to left pin, then remove it and join center pin to right pin. Now wait for a few seconds and then again remove the jumper and join the center pin to left pin.
Make sure to turn the PC off before opening the cabinet and resetting the jumper.

C. By Using MS DOS Command:
This method works only if you have access to the system when its turned on because this method requires MS DOS. Open Command Prompt from Programs menu and provide following commands one bye one:
debug
o 70 2E
o 71 FF
quit
NOTE: The first character in the above commands is "O" and not the number 0.
After providing the above commands, restart your system and it should reset the CMOS Settings along with the BIOS password.
If you are curious to know how it works? then let me explain the above commands:
In this method we are using the Debug tool of MS DOS. The "O" character present at first in these commands, outputs the values to IO ports. The number 70 and 71 are port numbers which are used to access CMOS memory. By providing FF value we are telling CMOS that there is an invalid checksum and it resets the CMOS settings as well as BIOS password.

SOURCE: I am facing a problem

It sounds like you need to change a BIOS setting. I don't have this MoBo, but on others there is a toggle to make the integrated graphics primary or secondary. You would need to change it to secondary. On this card this should happen automatically - so check BIOS settings and that your new card is properly seated in the slot.

From http://www.intel.com/support/motherboards/desktop/sb/cs-022225.htm
Installing External Graphics Cards
If you want to install a 3rd party external graphics card instead of using the onboard graphics, follow these steps:

  1. Install the 3rd party external graphics card, following the installation instructions that come with the card.
  2. Integrated graphics is automatically turned off.

How can u tell your motherborad is bad


Disconnect the power cord form the power supply, be sure the power supply is set for 110 or 220 volts depending on your location and power and double check it (most have a 110/220 switch) Feel/look at the back of the power supply to determine if the fan is working. http://pcsupport.about.com/od/toolsofthetrade/f/powersupplytest.htm If the fan is working, try another power supply anyway. Plug the computer directly into a known-good (a lamp works) power outlet Check to be sure you do not have a motherboard stand-off in the wrong position and shorting-out the bottom of the motherboard. Inspect/shake and listen for loose metallic objects (loose screws) on top of and under the motherboard and in expansion board slots. Look carefully at the ISA and PCI slots, see if any of the contacts got bent/shorted-out. Sometimes an expansion board will dislodge one and it will be pushed into the bottom of the slot. Inspect the motherboard for broken or burnt components. Carefully inspect the motherboard for black soot from bad bearings and clean and replace the culprit. Look for bent/shorted pins on the motherboard headers and straighten. Be sure the speaker is plugged into the motherboard. If you hear beeps. Decode the beep code. If not, double-check all jumpers. Push down on all chips that have sockets in attempt to reseat them. What CPU are you using? Be sure the core voltage is correct. Be sure the CMOS battery jumper is in the correct position. Some distributors purposely ship motherboards with the jumper in the wrong position. Find the jumper that clears the CMOS, put it into the clear position for several minutes, put it back in the normal position, plug-in the power cord, and push the power-on button. If you apply power to the motherboard with the jumper in the clear position you may damage the motherboard. Pull all boards except video. Disconnect all cables going to all drives, pull all cables except power, power on, and speaker, connect the power supply to the motherboard (the black wires go in the middle on AT power supply connectors--"Black OK, red your dead"), reseat the memory, plug-in and screw-down the display adapter and nothing else (push down on the top, front of the adapter and make sure it is properly seated by looking at it all along the PCI or AGP connector), connect the power-on switch and the speaker. Check the monitor plug for bent or pushed-in pins, connect the monitor and nothing else. Check the monitor power cable. Reseat/replace the memory. Check for Motherboard Electrolytic Capacitor Failures Check the CPU for bent pins. Try another processor. Note: If you apply power to a motherboard with an Athlon or Duron processor without the CPU fan connected, even for a few seconds, you will fry it (see http://duxcw.com/digest/guides/cpu/socketa/heattip.html). Check the CMOS battery with a multi-meter. Should be around 3 volts (2.8 is ok). Try a different video board. See if the CPU and memory will work with another motherboard. Pull the motherboard, set it on the box it came in, install video, memory, CPU, power, and power on. See if it boots. I have seen several instances where this works when the board will not work in the case. And, when reinstalled in the case, it continues to work. I have also seen where it didn't work out of the case immediately, but did work the next day and continued to work. One of those mysteries. Temperamental computers with minds of there own. Replace the motherboard.

Dell optiplex gx520 flashing yellow light on motherboard


According to the information you gave it seems it can still be the RAM. I've had a few PC's unable to startup due to bad memory.

Either that or the the front panel conectors are wrongly connected. Sometimes they do have a color code, but it's best to reference the manual. Can be the button . . .

If this is no help, I'd like to know more.

Hi,
There are jumpers on the motherboard,
check all jumpers are set correctly, as from the user manual, this could be a problem.

check all your front lights are wired properly
power button, reset switch, must be correct too.
double/treble check them before building it.

Power problem to cmputer


Hi,
Kindly check the connection from the front power button to the motherboard. The front power button wire may not be plugged into the correct jumper.
if that wire is hooked correctly, remove the memory modules from the system and all other wires from the board , except the power supply connectors to the board and then power it on , check the status of the light on the power button.
if you can provide us with the model number of the motherboard , we would be able to help you better

No signal to the monitor


Its actually a configuration problem

1.) ensure that the clock speed jumper is set propperly according to your processor
2.) ensure the the cmos jumper is set correctly
3.) check that all jumper settings are correct accorind to your hardware as described by the manual
4.) make certin that all the power cable / s is in propperly, some boards require the main power cable plus the extra 4 pin yellow x 2 black x 2 to poer the processor,, there should be a place to plug it in on the board itself

if that fails then
1.) unplug the system
2.) remove the cmos battery and the rams
3.) press and hold the power button for 10 seconds then release
4.) replace the memory followed by the cmos battery

if that fails
check that your processor is working..
