Hello Badcap members!
My first time trying to repair a motherboard. I'm stumped.
My setup
MSI-7207 (K8NGM2-L) ver 1.0
1 GB Ram
GeForce 7900GS
420 Watt PC Power and Cooling power supply
Problems:
requires 2 or more bootups
does not recognize the Video card (PCI Express)
What I have done so far:
Ruled out power supply. Power supply tested out ok. Swapped out power supply with same problems as above.
Ruled out video card. Video card works in another setup.
Using Blue ESR meter tested all the electrolytic capacitors in circuit - they read .00
unsoldered two capacitors
Rubycom MBZ
6.3v 3300 mF
date code TO546 (week of November 6, 2005).
Out of circuit ESR = .00, DC Ohms = infinite
United Chemi-con KZG
16v 1500 mF
Date code 5 (2) DG (December 7, 2005).
Out of circuit ESR = .00, DC Ohms = infinite
None of the capacitors show bulging or venting.
Suggestions? Would you replace all of the capacitors or just the United Chemi-cons?
Thanks,
Curt
