Question about Intel Desktop Board D845EPI Motherboard

1 Answer

No display on monitor

I replaced the power supply and mother board on my PC. The fans all turn on, the green LED light on the motherboard turns on, and the light on the front of the PC turns on but nothing else happens. When I turn the switch to the power supply off, the PC makes the noise it should when turning off. All cables were applied exactly like the original installation.

Thanks
Preston

    When it shuts off, it just makes one beep. When started, the monitor remains in the "sleep" mode and pressing the delete button does not initiate a response either. I noticed that when it is started the 3 lock keys at the top of the keyboard light up then go away immediately. Reconnecting the plugs also did not help

    From what you are reporting, ther is something that is not connected properly or completely. The single beep and then the keyboard lights coming on are generally an indicator that the motherboard is booting up. Is the video integrated into the motherboard or on a separate card? Do you have another video card?

    When you say that when shutting off, it makes the "noise it should when turning off", what do you mean? Are you hearing the Windows sounds or just some beeps?
    When the computer is started, do you see anything on the monitor at all? Any BIOS messages or startups from the system at all?
    As the computer is started, try pressing the Delete key and see if the BIOS comes up. If you can see that, then the power is getting to the system and you can also see what video is selected there.
    If you can't get to that (and you may have already done this), disconnect and reconnect all of the plugs and re-seat the RAM.

Will not power up. Replaced bad power supply(burned circuit board inside PSU) but still does not power up, PSU is ok. When power on button is pushed CPU fan turns for about 1/2 second but nothing else....


Sounds to me like when the power supply went out it allowed a surge to hit the mother board and you will have to replace it also .Look at the mother board and see if there is a green LED light showing if it is you are getting power to it and you have capacitors blown if not recheck you connections from the power supply and MB if they are all tight and correct then just figure on replacing the mother board

Test your PSU or replace it if your power supply units fan is not working your PSU is faulty

One bad lead can cause a computer to continue on a cycle or to shutdown or fail to detect/ boot up a computer hard drive

Test all leads that attach to your hard drive including electrical extensions,IDE,SATA

the leads from your "((motherboard to your hard drive))" make sure they have a secure connection and are not faulty or just replace them they could be faulty
make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty even the electrical extensions or just replace them they could be faulty a computer needs its connections to continue its cycle and have an end so any faulty leads will end up with a computer error hope this helps

I shipped my gateway to the philippines and had been using it until I had to leave. It has sat idle for 2 1/2 years. When i returned I brought new parts to upgrade, harddrive, memory, and a new windows xp...


Hello sir hi, try cleaning the memory modules of your PC. also review your power supply connection. and check the following sequence of events. 1. power on the PC. 2. fan should be blowing. 3. keyboard light, scroll, numlock and capslock lit and then goes off. (if this does not lit, you have a mother board problem) 4. you should hear a beep. (1 beep is normal, 1 long and 2or3 short beeps, means display problem) 5. the numlock is lit. (no light means problem on the motherboard) 6. the display monitor will now display the CMOS. 7. your drive should turn/spin or HD led lights.
Im not so sure if the motherboard develops errors due to being not used for a long time, and may now have slimes and battery leaks that may be present on the board, a visual inspection is needed here, remove your motherboard out of the case and inspect all area for chemical creeps.

No display in monitor when i switch on my pc, i can see display on monitor after switching on the cpu for 5 or 6 times


Hello sir, hi, check out the following: I'm assuming the things that you may have forgotten.
1. is the 4 pin 12V Molex power connector connected to the mother board? 2. did you use a a good and tested memory module? have this module tested first on another PC. 3. Is your memory slot free of dust and dirt? if not clean it up. 4. is you power supply fan and processor fan spins when power is on? 5. Try powering ONLY the motherboard connected to a video display, no sata/ide cable with a tested memory installed. 6. try another Power Supply box. 7. Is your processor mounted properly? 8. when you apply power look at the keyboard lights, 3 lights initial power on then 1 light the numlock led is on. 9. do you have a plugged in usb device, remove this device as you power on the motherboard. 10. do every thing again and double check.
if all else failed, bad mother board. have this checked by a technician.

NEW BIOSTAR MOTHERBOARD DOES NOT BOOT


Good day sir, let try to test first the power supply, Unplug the power cord, remove the 20 pin (24 pin for the late model) molex power connector from the motherboard, plug in the power cord, get a 2 to 4 inch jumper wire, short the green wire with any of the red or black wire on the molex 20 pin power plug, the result maybe the following:
  1. you will see the power supply fan turn. you power supply is in good order. replug the power supply, and test again.
  2. you will see the fan turn for a few second then stops. you power supply is selective, and may require a different type of motherboard. Get a new one.
  3. you wont see the fan turn at all. get a new one.
If in case you are with #1. uinplug the power cord and remove all the expansion cards, data cables from the hard disk and cd drives. we are trying to isolate the problem. make sure that the only connected cables on the motherboard are as follows:
  1. 20 pin power cable.
  2. 4 pin 12 volt power cable (if applicable)
  3. speaker
  4. power switch
  5. power led
Test the pc once more. plug in the PC. If still the board wont power on. problem with your motherboard. Note:make sure your RAM is good. Hope this helps.

We have repaired many of these systems. The board was damaged when the power supply shorted. You can get replacement motherboards at www.barebonekit.net click on the link on the left side for motherboards and look for Emachine.

I hope this helps, if so please rate my solution.

Mother board no display


Looks like the lights are on? Fans spin? Sounds like the harddrives spinning? The power supply is bad. has just enough power to light lights, and spin fans, but not enough for the processor. (No beep sounds, because BIOS hasn't done a memory count. It's not going to)

ALL the lights use less than 1 Watt.
EACH fan uses 2 to 3 Watts.
The harddrive just sitting there spinning, uses about 5 watts.

Processors use 55 Watts to 125 Watts. Depends on the processor.
Not enough power to turn the processor on, the computer won't work. Computer isn't working there isn't anything to turn the monitor on. No Signal.
