How to Fix some Motherboard problems

[TBoneit]

Here at work we have fixed several motherboards that were having trouble posting or booting into windows.

This will only work if you are handy with a soldering gun.

Look at the motherboard, if any of the capacitors have bulging tops instead of being flat then replacing them will oftentimes fix the motherboard.

You will need to pull the board and unsolder the old ones and replace them with the proper value in voltage and capacity, 18,000 microfarads 12v for example. Be carefull to indicate polarity befroe removing them as they are polarity sensitive.

When there is spare time, we do this here at work. We just did 3 DFI AK75-EC athlon motherboards in the last month. These are going back to 2001 or so. They support up to around Athlon 2000 with the 266 FSB. Then we use them during refurbing of used computers to sell to frugal buyers where price matters not features. Anyway our cost was Zero as we pulled the capacitors from Dead boards we keep on hand for parts.

We've also had a couple of mobos where the failure was the 20 pin ATX power connector to the mobo. You could tell as it was burned, blackened and melted. Changing it restored those mobos too. so don't just scrap, look and decide if you want to do it. It won't pay for someone else to do it.

Some of the things we've had people buy in the last month where only price mattered was a HP PII 266 $30 computer and a Dual P3 450Mhz for $79

Also sold out before we even got the price on it a Dell P4 1.6 w/512, XP Home, 16X Sony DVD DL burner, KB and mouse w/17" flat screen, not flat panel monitor @$279 and a 3Ghz P4HT with 120Gb and 512, XP home and CD burner @$269 in a Antec Server case. Nice case!
