[ubuntu-my] Mystery at the office, slightly off-topic

[Wan M Fahmi Wan Azmi]

Another Experience to share, my PC shuts down on it's own and can't be
switched on. After a few minutes, (sometimes hours), I can boot it up.  It
works for a random number of minutes or hours. Initially I thought there's
an over heating problem. I cleaned the fan, re-apply thermal paste, clean
the case bla bla bla...
But the problem persisted. At last, I opened up the power supply box (inside
the PC) and found the capacitors are popped and are leaking (Noticed the
yellowish stuff on the component). It was late at night and I had another
old power supply (different connectors)  an too much time on my hand.The
capacitors matched so I swapped the capacitors.
The PC now works perfectly, running 24/7.

Morale of the story. Capacitors have a life span. Once it pops, you need to
replace them. If your motherboard is busted, Check the capacitors. It will
smell acrid, like burning plastic. Try replacing them and you might just
save a few bucks!

WARNING: Capacitors keeps electrical charge. Disconnect from the wall socket
and let it stand for a few hours, just to be sure.

Cheers
