    Recently my monitor started losing video signal from one of my old PCs - it displays a message and goes black. I guessed it has something to do with the cable (because it sometimes loses colors when I move it - so I'll just go and get a new one, no problem) but I checked out the video card - ati Radeon 9600 - as well and lo and behold, 3 capacitors have spilled their guts out. I really don't want to buy a new card just because of 3 capacitors I can easily replace. Problem is, I'm not sure about their rating.

    Here they are: http://i41.tinypic.com/33usqw0.jpg

    Are these 1000uF 6.3v ? :confused:

    PS: Thanks for moving the thread here and sorry for posting in the wrong forum!

    Yes, 1000 uF / 6.3 V. It's worrying that three have failed catastrophically and simultaneously - it looks more like damage than old age. It might be prudent to measure the voltage across the caps in operation, as the chances are they've either been subjected to an overvoltage condition, or their rated ripple current has been exceeded.

    ^ I completely agree with you about the damage issue.
    This video card is less than 5 years old, and these capacitors should last longer than that as far as I know.

    Thanks for the reply!!!

    it can also be due to heat buildup inside the cabinet
