How to know your motherboard are dying

How will you now that your motherboard is dying? This has happened to me twice now. First time it was the BIOS chip that had failed on me. The board refused to get past the "verifying dmi pool data" message. New board on that one. Second time around it was the CPU overheating. If you don't mind playing with the hardware and you have some sort of speaker on the motherboard then try the following suggestions: Remove ALL of the pci cards, the ram modules and the mouse (yes, the mouse as well) and bare-boot the board. (If you are using a separate graphics card then unplug that too for the moment). If you have a speaker connected to the board then when you try and boot you will hear a long series of continuous beeps (See PC Boot Problems), which means that the board is trying to tell you that you have no ram installed. This is good because it means that the board's BIOS chip and the CPU are working just fine at this point.If you hear nothing then it's time to either try another CPU or to change the board. Game over...If you get past this point then switch off and plug the ram back in, and then try a re-boot. If you have more than one module then switch off and try each one separately before booting. If the problem is the ram then this will soon show up. If you get to this point then you should hear a different set of beeps (usually one long and three short). This means the board is looking for a graphics card.Now switch off, plug in the graphics card (if it is off-board) and try booting again. If you get a hang-up this time then you have a graphics card problem. If all is ok at this point then you can turn off the pc, replace each pci card one-by-one and try booting every time you plug one in. If the problem is with one of the cards then this will soon show up. I suspect you may fall over at one of the first two options, which means either board or CPU.

Note: not everyone knows how to tweak and configure a PC. So if you’re one of them, don’t try to experiment because it will do more damage to your system or other components. But if you got lucky, then that’s good. If you’re not sure of what you are doing on how to troubleshoot your own PC try to look for a Computer Technician because he/she knows what to do.
