Re: Hardware Question about RAM and Capacitors
If you're really feeling ambitious, you can replace the capacitors on
the motherboard (or at least in the old days you could).
Good luck!

About a year ago it locked-up and on reboot it beeped like crazy before the POST got very far. I started to go through and remove one stick of RAM at a time to see if it was bad, and on the first one, the one in slot 4, after taking it out, it rebooted and worked fine. So I figured that stick was just bad and left it at that. I didn't have any other sticks of the right DDR type and I didn't bother to replace it.

It seemed odd two sticks could go bad at the same time, so I tried them in that first slot and both worked. I tried adding some back and no matter the combination except for one single stick, always got a beep-fest. So I think all the RAM is good, but the last three slots are bad (or maybe just the 2nd is bad, and then the 3rd and 4th can't work without the 2nd??).

One is worse looking than the other two (eh?), the two have some part of their tops that still look shiny silver. I've heard of capacitors going bad on motherboards, but never saw any. Is this rust a sign of failure and could their failure be the cause of the RAM slot problems?

It has boinc/seti/asteroids, webserver(s) and other stuff running (except when running BOINC its not heavily stressed but generally is doing _some_ work pretty much all the time).
