Bad Motherboard???

By toexposure ·
I just reformatted a hardrive for one of my students. I also installed a new sound card and had the pc working beautifly. Now the system will not send a image to the monitor, nor will the mouse, or keyboard work. It looks as if there is eiher an electrical problem or the motherboard is going. I checked all cables, they are fine. I am totally lost on this one. Maybe the answer is looking me straight in the face!! Please help. You can post or e-mail me. Thanks a bunch :)

Bad Motherboard???

Try downloading updated video drivers from another machine,then trouble shoot other problems thru device manager to see if you are a conflict with sound card.Make sure that you have power going to the machine,check powersupply to see if it comes on.

Your first assumption may be right. This type of problem can be related to a bad mother board, or a bad power supply, and if it is, it can be hard to determine which.
It may however, be one of a few other things. I have seen this same problem occurunder a few other circumstances. It could also be on of the following:
1) incorrect IDE setup
2) bad video card
3) bad HDD
4) adapter card in wrong slot type
Do you hear any sounds from the internal speakers when you start the computer?
if you do, is is quite likely a video card problem. You will need to find a list of what the beeps mean for your mother board.
If you do not hear beeps, it could also be possible that the speaker is dead or not connected, in this case, simply try another video card.
If the problem is a bad IDE setting, you can solve this by double checking all the IDE cables, and jumper settings on IDE drives (HDD, CD-ROM, etc..). You would be suprised how often this causes problems.
To check if it is a bad HDD,simply disconnect it, and connect one you know is working. If it boots, the HDD needs replacing.
Lastly, the problem can be caused by adapter cards in the wrong slot, remove any unnecessary cards (NIC, sound,game ports) and try booting. If it works you will need to find out which is causing the problem. Put one back in, and boot again. Continue this until it does not boot. The last card inserted is the faulty one.

Check to make sure that the motherboard is setted properly on the plate and that it is not touching any medal pieces on the plate. That will short out the motherboard as well.

Hope this helps.

Check to see if the Power Supply fan is working,then make sure that you have the correct orientation for the cables,one of the cables may be flipped wrong
Check memory to insure that they are seated properly.

Firt things first. The A/C outlet is good right? Of course it is....:)You stated that it "was" working ok, right? Ok, now, remove all the cards from system. Unplug the mouse, HD,(power and IDE cable) and floppy (power and ribbon cable). The object is to have only the video, KB, and power connected. Try powering up. If it boots, and you can see video, the system board is more then likely good. Also check for fan movement on the power supply after powering up. Ignore the several error messages you will recieve, in fact, as soon as you see a memory count on the screen you can power off. If you do not get video, then you will want to check the momory chips for proper insertion.(BE GENTLE!) If you have more then one DIMM, remove all but one andtry to power up again. If you still do not recieve video, try swapping a DIMM with another. You may also have a bad memory DIMM. If you can successfully power up , then continue from here. Now install floppy and power up again. Next the HD, then thesound card, then the modem. You should be able to determine what device or card if any may be causing a conflict. Good luck!
