Can a motherboard be repaired?
I had that question for a motherboard that seemed to be suffering with static discharge Here is what member Binnampa sent me by email:
Repairing damage caused by static electricity is difficult.
First you must be able to identify which component got zapped. Then locating a replacement part, and replacing the damaged part.
Sometimes, the shock will trip a triac or another circuit protection device. This can sometimes be cleared by reseating components. If the CPU or Video Circuitry is not soldered down, it can be removed and put back in. This will sometimes allow the triac to reset. Then the machine MAY work again.

I, personally, would never try to repair a motherboard. This is especially true if the damage is due to static electricity. Often damage caused this way is hard to really pin down. Often you just have weird things happen, maybe more frequent lock ups or freezes in programs for example. If a motherboard is bad, the decision is to either replace the motherboard or replace the PC. If the motherboard on my old clunker PC goes, Iwill replace the PC, because it is so old it wouldn't be worth putting a new motherboard in. Kind of like throwing good money after bad. If a PC motherboard goes and the PC is a year old then I would replace the motherboard. Between 1-3 years, I would consider it depending upon how much the motherboard costs relative to a new PC. Over 3 years, I would replace the PC.
This is,of course,based upon PCs available in US on the US economy. School of thought might be different in other parts of the world.
When looking at various motherboards, I often notice an FSB speed listed, what does that mean? I know what the front side bus speed of a processor is, so I'm guessing that the motherboard's FSB is the highest FSB speed you're processor can go to (on that motherboard at least) but I have my doubts. Anyone know for sure?
With the recent lost of one machine (most likely the motherboard) I am sad that there is not a better way to fix the circuitry. When turning it on the fan on the CPU starts to rotate and then stops - the power light does not come on. I am also hoping that my one stick of 512MB did not also get zapped too.
As for the above question... FSB:

Computer Doctor: FSB is just another name for the motherboard speed, or the speed of the socket or slot that the processor is plugged into. It is also called the system bus. It's important to consider FSB speeds when planning a motherboard purchase because the speed of the FSB is the speed of the motherboard, and also the speed of the bus that the processor is plugged into. As with computer-related factors, the faster the FST the better. For example, compare two Pentium III 800MHz systems. The PIII 800 can be set up to run at either an 8x multiplier on a 100MHz FSB, or at a 6x multiplier on a 133MHz FSB. Even though both result in a CPU speed of 800MHz, the first one has a memory transfer speed of (8-bytes * 100MHz) 800 MB/sec, while the second example would have a memory transfer speed of (8-bytes * 133MHz) 1,067 MB/sec, which is 33% faster. Thus while both would process information at the same speed, the latter system would be able to read and write data from memory 33% faster than the first. |
Motherboards are to much of a hassle to fix. The time it takes to track down anything from a bad component to a bad or fried circuit, you have already lost money on the deal. I used to have a gadget that you could hook up to the motherboard and it would send impulses through the board and determine if it was a circuitry problem or a component problem. Circuit problems where a toss, component problems still left you with the problem of narrowing the bad part down. So you still ended up doing allot more work than needed.
