My lab is down, failed switch and how to fix it

Often when a computers mainboard fails, the reason is leaking capacitor(s). I think at least the premium mainboards today, use solid state capacitors. If your mainboard is somewhat old, it could be a good idea to check it for leaking capacitors, and eventually replace them. Edit: If your computer, out of nothing, starts to act strange, it could also be that the PSU needs to be replaced.

I ducked for cover a couple of years ago as I thought someone was doing a drive by on me only to realize the big cap in my pc psu popped. It was seriously loud and then came that electronic smell.

I have replaced a lot of failed capacitors in wall wart power supplies, PC motherboards, PC power supplies, TVs, stereos, even my Sears garage door opener radio receiver board. I seldom even bother to troubleshoot anything- just swap the caps and it’s fixed.
These are a couple of eBay sellers who I’ve purchased caps from.
