is there a method to wake computer from crash

acer aspire 7740-5691 laptop windows 7
I did repair install and sfc scannow

when running many programs (videos) computer crashes and only displays moving mouse cursor on a black screen

sometimes I press the power button which wakes computer from sleep
Control Panel\All Control Panel Items\Power Options\System Settings
and I am taken back to the login screen where I can get back to windows screen

other times ctrl-alt-delete start task manager works

sometimes waiting many minutes


I do not wish to restart computer every time computer crashes

A crash means that something has gone really wrong and Windows cannot recover on its own.

Your computer should not be crashing so often.  I would try to correct the crashing.  As you did the repair install and sfc scannow you should look into other causes.

I would scan for malware using malwarebyte's anti malware program.

I would also do a complte scan with your anti-virus software.

If that doesn't improve things I'd back up all of my data, and do a factory restore, then install all applications again and copy the data back from your backups.

If I had a computer crash more than once a week (I don't) would do the above advice.

Set computer sleep to Never and see if that makes the difference.

If you do not want to disable Sleep, try below setting.
Prevent idling to sleep
