Thanks! I tried setting it in the power settings, (control panel) but this worked great :)
It started when I installed AVG antivirus (company I work for made everyone install it) and then one of my games quit working (clan lord online RPG) (maybe port 5010 is blocked?), the screen shutoff was changed to one minute (so annoying) and many web pages no longer display and instead say "blocked, this site contains advertising" - and one of the blocked sites is amazon affiliate links. I uninstalled AVG but the problems all remain. I guess I'll re-install AVG since the company wanted us to.
Just wanted to say thanks for helping me solve one of the three AVG problems :)
