I replaced a couple of damaged caps, and now the onboard speaker clicks constantly. Swapping the PS made no difference. Do I have more caps toasted, or is something else going on?
Long story:
I was doing some spyware cleanup for a friend who had been having some lockup problems. It also seemed to blank and die when not actively used (even after disabling all power management I could find in OS and BIOS).
The cleanup went fine, but when I went to turn the machine on again after being away for a few days it wouldn't post at all. I reset the bios, unplugged devices (including the PS from the motherboard to drain all power). No luck. I swapped in a different PS and within a few seconds I saw two of the motherboard caps buldge and squeal a bit. I pulled the power asap and let it sit, thinking I fried it and was going to be replacing the board. I haven't dared use that PS on anything else, so I don't know if it was board or PS causing trouble.
After the holidays, I hooked it up one last time tonight and ran fine. I thought it was my lucky day, and so I spent a few minutes digging around my dead MB box and found two 10v 1500uf caps (the same spec as the buldged ones) and used those.
The system seems to run fine, but the sound coming from the PC speaker is just about like what you'd hear from a kid with a playing card in his bike spokes.
I've looked carefully at all the other components and don't see any visible damage. Any pointers? Or should I just bite the bullet and replace the board?
