For example it is very common for simple voltage tests to appear OK but the PC may have spurious weird problems. Plugging in my tester has shown at least one LED off - change the PS and bingo the computer is OK again. Repairing a PSU, unless it is a non-standard model, is usually not worth the expense compared with the price of a new one these days. Rob
