weird display problems

my comp has worked fine with no problems for a while then all of a suden when i load windows i get a " no signal " from my monitor ( Acer 22" lcd ). If i remove my dvi cable then plug it back in i get video back but is showing up as non pnp monitor and stuck at 1024 by 768 for my max resolution. if i load in safe mode it works rite away without disconnecting. i've tried changing drivers, formating and reinstalling vista but no luck.

any help would be appreciated

I think that leaves it down to either the monitor or the cable.

Do you have another computer you can hook the monitor up to.
