Two days ago, I decided to change my POWER MANAGEMENT settings. I had them orignially setup in a way that would turn off the hard disks after 30 min and turn off the monitor after 15 minutes. I decided to tirn everything off (in other words, everything always ON).
So far, I haven't experienced a black screen crash. I will try a few more combinations that I know usually crashes the computer and will come back for a report.
Also, I would like to try the manual settings in the BIOS as sugested above, but I do not know what I should enter in there...
