I inherited a comp which has about 10 times+ the capacity of my own, and its been sitting there for 2 years. but was in use right up to the time it came to me.

I tried at last to get the thing hooked up, its just a regular tower type, anyway nothing happens except an audible noise kinda like a long buzz.

Theres a switch on the back 0/1, when you hit that it stops but still nothing else.

Anyone any idea whats going on?
