Is the computer frozen or just the desktop? Try CTRL-ALT-F3 and see if terminal mode loads.If it does, log in and type:

killall plasmashell && kstart5 plasmashell

This should restart the desktop. Then put it in standby again. Wait a minute or so, then wake it up. If it's frozen again, CRTL-ALT-F3 again and see if any messages have been added to the terminal. If not, enter:

sudo dmesg

And see what messages were generated from the time you tried to wake it up.

Post any messages.

The computer is frozen and only the frozen mouse pointer and a blank screen is visible

OK, time to start reviewing logs to see what might be causing it.
