Gigabyte Motherboard Issue

  1. Hey everyone,

    I've tried everything I can possibly think of to fix the Gigabyte GA-7VTXE+ motherboard. What happens when you turn it on is that the processor fan flickers and then doesn't do anything. The light on the motherboard itself turns on but I get no activity from any other part. I've tried replacing the power supply with the new 420w power supplies with nothing else connected inside the machine. I get the same result. I also have tried to take the battery out of the machine over night and came back, and I put a new battery in it along with trying the old one and it still does the same thing. I'm up for any suggestions on what I can do with this. We have had more than 50 computers go down with this type of problem and the company that supplied us with the machines are screwing us on the warrenty. The manufacturying warrenty ran out a long time ago. Are all these motherboards faulty?

    In need of any help,
    Switch

    Are they overheating cpu's
    you don't say if the fan comes back on
    does the board at least boot to bios
    If the answer is yes to first one
    If you have a spot for another fan to plug into try that get it running so you can get to bios
    I tried to get manual from gigabite site no go there
    so I can't say if there is a bios option for fan controll
    next check to see if this dealer stuck some bad program on machine that is shutting down the fan settings may be goofy

    Good Luck

    Well maybe the motherboard could be bad . But you said have 50 machines with the same board and same problem .. THis itself sounds strange you can contact Gigabyte I believe they have life time warrenty on there boards.. Gigabyte usually pretty good board..

    So what else do all these computers have in common or we talking about a single machine here>>

    Defective capacitors on motherboard.

    Check the motherboards for leaking or bulging capacitors. Often there is little evidence of a problem with the capacitors. Look for capacitors in a row of the same type and one slightly taller with signs of bulging at the bottom of the capacitors.

    A few years ago a large quantity of defective capacitors were supplied to all the major motherboard manufacturers including Gigabyte.
    If I remember correctly Abit was the only company admitting to receiving the bad capacitors.

    I don't think any of the retail computer companies (HP personal experience) ever admitted to the problem. Simply crossed their fingers and hoped the motherboards lasted until the warranty ended and many will work past the warranty, depending on how often you use your computer.
    Even if the computer or motherboard is out of warranty compensation should be offered. This is a well known problem in the computer parts industry.

    I have read in several forums of people complaining of motherboards replaced (retail computer companies) under warranty and the replacement failed soon after being replaced with the same motherboard with defective capacitors.

    Also, replacing the defective capacitors does not always fix the problem often other componets fail also due to the defective capacitors.

    I have never used this repair service but it looks as if they specialize in repairing these motherboards and have links to suppliers for the correct replacement capacitors. I have ordered replacements from a supplier they recommend, http://www.mouser.com/

    "The origins of the motherboard malaise seem a lesson in how not to commit corporate espionage."
    "a scientist stole the formula for an electrolyte from his employer in Japan and began using it himself at the Chinese branch of a Taiwanese electrolyte manufacturer. He or his colleagues then sold the formula to an electrolyte maker in Taiwan, which began producing it for Taiwanese and possibly other capacitor firms. Unfortunately, the formula as sold was incomplete."

    Thanks for the responces

    Thanks for all the responses Triton, tbrunt3, and Samstoned. The motherboards try and turn on but nothing comes up not even bios. The processor fan clicks and then doesn't turn on. Like I said the power supply looked like the problem but at first but when I tried a new power supply the same thing happened. I will contact Gigabyte and find if the school district that i work at will get some compensation for all the defaulty motherboards purchased. Also thanks for the pictures and links Triton thanks a lot for all the info. I did look at the motherboards and I saw the signs of leaking and bulging capacitors on all the motherboards that are not working.

    Just to tie up loose ends

    Hi,

    I had the same problem and PM Switch for his solution but no response. In the end I found out I had to update my BIOS to support the faster CPU and I had to remove the thermal sensor from the CPU. With the thermal sensor attached the computer would power up and die after ~2sec. Now it boots up.

    Cheers!
