Windows 7 Can't Sleep/Hibernate

[MrRiceamony]

I've recently replaced my old PC's PSU to its original one so i can use it on my new pc build. I've also removed its GPU. I've later tested the PC, and it seemed to work fine, except the Sleep and Hibernation option is greyed out in the start menu. I've uninstalled all or most of the Nvidia drivers, which still hasn't worked out. Anyone got any ideas of what the problem may be?

Nevermind, I've finished my life searching through the depths of it. Wandering from shore to shore, visiting the world's wonders, I have found the answer. I would like to thank the president, my parents, and everyone else. Thank you. (I've found the fix )
