it must be driver related issue
however as you said you have installed the latest drivers
turning off monitor by os is done by sending a message to the system &
system turns on the display whenever it detects mouse or keyboard event
try out a shareware at
http://www.rtsoftwares.com
don'nt think it will change situaton as the issue seems to be of a
corrupted/incorrectly installed driver, but it might work
