thanks willawake for your reply.

1.If i use digital camera to capture, i think it is hard to see the bad caps but by using hand to feel it, there are some different with others(good one)

2.There are no burning sign on the board, everything is perfect.

3.For the SP-97V, i abandon this board more than 1 year, so i dig it out just to warm up only!BTW no bad caps on the board as the board have less caps on it.

quite weird too!I have 3 board with these symptom
1.Gigabyte GA-6BXDS(P2 400) (suddenly down and never come back)
2.ASUS...

1.some of the caps are bulging(330uF near the bios)

2.try with many working psu but still no POST while powering up.

Thank you for your reply

first problem:
I have a gigabyte GA-6BXDS(dual P2 processer) MB which on good condition.One day the MB shutdown by itself and once i reopen back the computer, no POST of that motherboard from that day.I even notice that some of the 330uF 25v cap are different from others.
The cpu caps are all fine.(SANYO)
The 330uF caps is CHOYO brand
Can replacing the 330uF help solve the problem or some part in the motherboard already said bye bye to you?

second problem:
same as above but this time is an old motherboard, asus SP-97V.No caps problem(i don't know...
