my pc wont wake up from sleep

[crunchraven]

hello guys, this is my problem
i think that the problem occured when i tried another graphic card on my pc to check if its better(at last i used the 1st one)
when i put my pc to sleep everything's alright,but when i press a button,its waking up(everything including cpu,fans and etc), but my monitor is black and i cant do anything..to recover i need to unplug it..i tried anything
any possible solution?

Is the monitor on? JK

Anyway, do you need to unplug the monitor or the computer to recover it? It wasn't clear in the post and makes a big difference.

In Windows, under power, advanced, look in the list for the c-states. Set the low limit for c3. That allows the pc to go to sleep, but not so deep that it shuts power totally off for the major components. Also make sure you use hybrid-sleep, not hibernate. If you have hibernate enabled, dump it totally. It's useless on a desktop as it's designed as a battery saver for laptops

i tried to fix it somehow..i put it in sleep mode and i opened the case and removed 1 of the rams...then i closed it from behind and opened it again...idk how but my bios returned to its defaults settings and..........magic................my pc goes and wakes from sleep normally again
took me days to find the sollution..really annoying
sooo a tip for all of u guys..when you tried out everything and nothing worked thats what you should do
