Answers are: Yes, yes, yes, & maybe. What processor[s] are/is in the mb. What form factor is the mb. I have a ton of mbs/boxes around here that I would be happy to give away though rather primitive. clyde ----- Original Message ----- From: Adam To: [email protected] Sent: Monday, August 03, 2009 8:21 PM Subject: [mhvlug] Power supply? Capacitor repair?
Hi again, everybody. I'm still working on my "second computer" project, as a spare time minimal cost fun thing, to try out four different distros without affecting my main computer. A few days ago I gave it a mild stress test, and when I woke up it had powered down and there was the familiar smell of Magic Smoke. Pressing the power button again caused the power LED to flash amber and then it would shut down again, with the smell of smoke again. After that, pressing the power button would do nothing until several hours had gone by, then pressing the power LED would flash amber again, and the whole cycle would repeat. My guess was a power supply problem, so the next day I /carefully/ took apart the old power supply but didn't see any major damage inside, except for one possibly burned out coil. I bought a new power supply and installed it today, but it's the same. When I press the power button, the power LED flashes amber and then it shuts down. Pressing the power button has no result until several hours later, when pressing it makes the power LED flash amber, then it shuts down, and the pattern continues. This model of motherboard is known for having capacitor problems, so I then looked at the motherboard more closely and discovered that two adjacent electrolytic capacitors on it were bulging a little on top. IIRC they're all supposed to be flat on top, like all the other electrolytics there. So my questions are: Could the problem be those two slightly bulging capacitors? If so, would I probably be able to replace them with just an ordinary soldering iron? Could I try to reassemble the original power supply and return the new one for a refund, or is that something for experts only? As mentioned, this is a minimal cost "fun" project, and already way over its limited budget. If it meant buying a new motherboard, I'd just scrap it for parts instead, and put my money toward a new primary system. Thanks /very/ much in advance for any advice or suggestions on this!
