My motherboard came gradually to a complete death and I'm trying to figure out if one can repair it by fixing some capacitors like in the old days.
I went through all the arrays of caps as well as the single ones with my multimeter and all seem fine at the first sight (loaded up with the 'beeper' mode and then showing some voltage, gradually decreasing).
But there are these boxy things with two thoroughly soldered pins, that I can't figure out:
Q: What are these?
They are of perfect cubic shape with side of about 1 cm (about 2/5 of an inch). Written on them is R50, but they show no resistance. There are similar components at various places on the board, labelled 1R2 or 3R3, but none of them have any measurable resistance.
I'll appreciate any help! In case I should supply some more info, I'm ready here with my lousy multimeter...
