It is Windows 7 Ultimate. (x64)
The HP computer (I mentioned above) needed a fdisk & reformat.
Instead of installing Windows 7 Ultimate again, I installed Windows 7 Pro. (x64)
PC has been on for 2 days & no hibernation problem.
(after Power Options disabled)
Will fdisk & reformat the Acer PC after backing up my files.
I hope this information is helpful to other members inflicted with this problem.
I thank all members that responded to my request for assistance !!!
