Computer appears to go into standby when it shouldn't
Posted on 2006-11-24
Hi there. I seem to have a problem with my current system and I'm trying to get some ideas on troubleshooting. Here are the symptoms:
While working in Windows, the machine will freeze (very briefly, sometimes it's not even noticeable) and then the monitor will go black, and then a couple seconds later, the monitor goes into power save. At this point, there is nothing that can be done to revive the system, and I have to force a restart.
Now... this happens at any given time (totally random), sometimes right after I restart... sometimes after I've been using the computer for 20 minutes or 2 hours. It happens when I have no applications open... or when I just have a game open... or just one application... or I'm just browsing the net... even sometimes it happens when the system is already in standby (so I just can't wake it up out of standby). There doesn't seem to be any common denominator pertaining to software.
Things I have already done:
Replaced the video card
uninstalled old video card's drivers and installed new video card's drivers
cleaned all the dust out of the insides
removed all cards and reseated them
replaced the monitor and it's cable
Still does it.....
