this sounds like it may be it.  the monitor has made crunching noises since
i got it; like 'stuff' floats to the bottom when i turn it off?

I have a view sonic graphis series G90f
I guess i will check to see if it is cathode ray tube monitor; hopefully
wont have to dig too deep to find out

thanks for the responses!!!
