I have a FIC VT-501 (200 MHz Pentium I) that, until recently, was my main computer. I've since upgraded to a P4, because the VT-501 machine stopped working.
The system was periodically unstable, nothing consistent. There is no visible evidence of bad capacitor plague on the motherboard or any peripheral card; however, nothing comes up on the screen when the computer is booted, although the computer acts normal. I'd like to keep it going, as it runs (ran) my 7-year-old's games quite well.
On the motherboard, there are nine 1000μF, 10V, 105°C capacitors labeled S.I. and something that looks like a not quite filled-in circle. My web research has failed to turn up the manufacturer. There are also fifteen 10μF, 25V, 105°C and one 100μF, 10V, 105°C units, all made by Su'scon, an identified bad performer.
There are no electrolytic capacitors on the video card (Diamond Stealth II S220).
There are two 470μF, 16V, 105°C capacitors on the Aureal AU8220 sound card; again, the manufacturer is unknown. They have a flattened diamond with a filled-in circle at each of the points. On the side, they have:
LL
105°C
(M)
There are also seven 10μF, 25V, 105°C and one 47μF, 16V, 105° capacitors by GSC, another notoriously bad provider.
Fortunately, I have just enough 1000μF, 10V capacitors left over after BE6-II recapping to hit those on the motherboard first.
Can anyone help on the identity of the two manufacturers, as well as provide suggestions on troubleshooting/similar experiences?
