This issue has only recently started, it's got me stumped.
Whenever we use the computer for more than ten minutes, or try and watch something via sky, or even a DVD, the monitor goes into sleep mode, the sound keeps playing, but it won't wake up even by mouse, or keyboard taps. Have to turn monitor off, then back on to bring about some life, then if you can get in a mouse click on a working icon in half a second, it will come back. However, if not, goes straight back to sleep.
Have rest monitor settings
Turned sleep mode off on monitor
Adjusted power settings in control panel to 'Performance'
Reseated graphics card and hoovered inside box.
Looks like all fans are working, I just can't see graphics fan when power on.
Tested it with work's laptop and the same issue is apparent.
Help?! Not gone as far as BIOS update yet, but is that going to do anything with the issue transferring from different computers?
