My monitor goes full green for seconds and also flickers somewhat during boot.This problem persists for initial 10-15 minutes of booting, after that it's working fine.This problem started when i kept the monitor off for some 3-4 hours one night.Also i cannot set my screen resolution to 1024 by 768 after this problem, however i was able to set the same prior to this problem.When i tried to set a higher screen resolution it showed 'Out of Frequency' message.I have noticed that when i keep the monitor off for few minutes and turn it on, it starts with the same problem and takes its time to settle down.I tried to update the display driver, but the message appeared 'Cannot continue the hardware update wizard' The wizard could not find a better match for ur hardware than the software you currently have installed.
