@haeckerfelix This reminds me of one of my better "I was a fool" stories which you might find amusing.
One day at work back before flat-screens my monitor kept making a zapping noise and briefly going blank. I filed a ticket asking for someone to look at it, then I had to add a sheepish comment admitting I'd realized why it was happening: I'd put my boots on top of the monitor to warm up and the snow on them was melting and dripping onto the capacitor.
The fix: paper towel under the boots.
