Win 7, from certain point, it starts to do this (as title described)
If put 'hibernate mode' then wake up, it does the same thing( wait 3-5 mins, then 'resuming windows...' shown on screen;
If put 'sleep mode' wake up works( screen shown content immediately).
tried solutions, none works,
Updated video driver to the latest;
changed different video cable, same thing;
same cable connect to a different pc, no issue.
