emachine t3092 (FIC AU31 MB)
AMD AthlonXP 3000+
Bestec ATX-300-12E Rev. D power supply
My pc had no video this morning, but appeared to be running. I held down the power button for a few seconds to shut it down, let it sit for a few seconds, and then rebooted it. Nothing happened - it did not POST and no info popped up on the screen. I tried this a few times & once it started to display info on the screen, but then went dead again (all fans were still running, so some juice was flowing).
I took the case cover off & blew out the huge amount of dust that had built up inside, hooked my monitor to the built-in graphics (I had it on an AGP graphics card) and still nothing. I've had the machine reboot mysteriously before in the past, but it would always come up fine & run like normal afterwards.
So I did some searching, and found a posting here that sounds like my problem:
https://www.badcaps.net/forum/showthread.php?t=7611
I checked the caps around my CPU and they appear to be hosed. They are all bulging to some extent & 3 of them have gunk oozing out the top. Doh!
The power supply appears to have valid voltage to all the pins, but I tested it out of the system with pins 14&15 shorted so it wasn't under load. Those caps look like the culprit though.
I had an old good MB that had some nice Rubycon MBZ caps on it, and my plan is to recap my board with those. I took the Rubycons off the old board and am going to attempt to put them on my board tonight. Has anyone had any success doing this - using harvested caps to fix a dead board? They're all the same rating of caps: 2200uF 6.3V caps & appear to be the same size.
If anyone has any advice for me I'd appreciate it - this is the first time I've recapped anything, but at least I have some soldering experience. I figure it's worth a shot!
On a side note - my wife finally got me a Blue ESR Meter for Christmas, which of course has not been put together yet. Doh! It would have been useful for checking the harvested Rubycons, but I need to try to get the PC up & running before I play with that.
I'm going to attach some pics I took. (Hmmm I keep getting "upload of file failed" messages. I'll try posting them in a response to this post)
Thanks!
