Hi Ed, thanks for the reply, but I did ground myself (at least I thought I did).
If I did in fact do some damage as you said, what would it be that I damaged? The
power switch light is not going on upon bootup, so do you suspect the power supply.
If it was a static issue then wouldn't it make sense the memory would have been what
I damaged? Do you think it is the video card, since I don't seem to have an input
signal? What would be my next step, checking the video card and then the power supply?
How would I determine if they are faulty? Thanks for your reply, and your help is
most appreciated.
Charles
