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

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

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
