My monitor looks like 'waves' when I surf the net or use explorer, there is a' !' mark against my video drivers in Device Mananger.I have re-installed them, but to no avail,it says to uninstall the old ones first, BUT if I uninstall them, will my monitor still work so I can put new drivers in??And does anyone have any idea what may have caused this,its horrible, the whole page moves up in waves.Thanks.
