Motherboard MS-6340 VER:1 (erp 140): Computer stops responding

From FVue
Jump to: navigation, search


Within 2 hours after startup, the computer stops working: the screen turns black and mouse/keyboard don't respond.

Rebooting doesn't work either. Within 2 seconds after power up, the motherboard powers down the hardddisk and produces a small click coming from a round black device named SAT-1205.

Only after a couple of hours the computer will boot again.

I can see bad capacitors (Chhsi 2700 uF, 6.3 V, diameter: 10 mm, height: 22 mm) on my motherboard.

I'm concerned about the following capacitors:

  • 2x 4700uF/6.3V, brand `Chhsi' (these look good)
  • 4x 2700uF/6.3V, brand `Chhsi' (swollen/bulged heads)


The capacitors turn out to be bad capacitors;

1. Consider replacing the motherboard - and probably the processor as well. Perhaps something more energy-efficient? The MS-6340 processor range burns 70 Watt while standing idle...

2. Are you reluctant throwing away things, just like me? You can always try to replace the faulty capacitors with new ones.

Contact MSI support. They were kind enough to send me new capacitors:

  • 4x 2700uF/6.3V, brand `3DVDK'
  • 2x 4700uF/6.3V, brand `nichicon'

You can consider to replace the capacitors yourself following these guidelines or use the repair service.

If you can't get the capacitors through MSI support, here's another place to buy them, e.g. Panasonic EEUFC0J272S. (€ 0.89) or Panasonic EEUFC0J272S (€ 1,20)

I'm having the exact same problems with another motherboard, MS-6340 VER:1 (erp 0000), VIA VT82C686A chipset. Erp 140 (this page) has VIA VT86C686B chipset.



The FDD connector was connected the wrong way: the flat cable red side was connected to pin 33-34.

Tried to install Ubuntu 7.10 on the repaired motherboard. Before installation was completed, the computer shut down and I was unable to power up the motherboard again, facing the same problem: within two seconds after bootup you hear one beep and the motherboard shuts down.
