I just got a new acer computer with windows7 preinstalled on it and experience that the computer freezes when it was idle for 30 mins and I come back and want to use it again. When I move the mouse to reactivate the screen, I can still see the cursor react to my mouse movement, but cannot click anything. It doesn't react to keyboard commands either and after a few seconds of moving the cursor, that one freezes as well and all I can do is a hard shut down. I customized the power settings already and turned off all sleep and hibernation options, so nothing will be turned off when the system is idle except for the screen after 30 mins. Still I am getting this problem and I noticed that it usually occurs when I have an application maximized when I leave the PC for 30 mins. If everything is minimized before I let the pc idle, the problem doesn't seem to occur.
Does anyone have any suggestions for a solution? I also did a ram and hdd test with returned no errors and reinstalled the windows preload. I need to know whether or not it's a hardware or software issue so I know whether or not I can have the machine replaced, but I do not have any way to test the rest of the hardware since it's an acer windows 7 preload I can't even install it on my toshiba laptop to test the preload.
