For voltage sensing, your meter will be safe but if measuring resistance/impedence (ohm-meter mode) you can damage components...

I believe this is true for both DVM and the old analog style.

i didn't even know anybody has an analog meter anymore....

checking resistance damage things???? you dont check resistance with power in the system, and as long as you arent dealing with any small circuits in the computer you'll be fine.... its when you start dealing with amperes that you can destroy things

if you check resistance with current flowing, you will fry the meter.

not true at all, a DVOM will put out less than 1v output in OHM mode, not enough to damage anything. checking a computer circut for resistance makes no sense anyway, volt testing is all that makes sense in a computer circut.
