PC won't go to sleep, just turn off the screen and freezes

When I close the lid or put the PC to sleep, the screen will turn off, fans will continue to blow, led lights are on and PC gets unresponsive to mouse, keyboard and power button, so the only option I have in order to use my PC is to long-press the power button tu cut the power off. It's a common trouble with no clear answer. Sometimes, just sometimes it gets to sleep if I try when I just turn the PC on and logged in, after a few minutes or tasks it's impossible to sleep the computer.

I've tried:

Updating drivers (with the manufacturer drivers, and after the format with Driver Booster 2 with no luck in non of those cases)
Updating BIOS firmware
Disabling windows media share
Disabling hibernate mode
Many many changes in power options
Getting RAM and SSD out and back on (deperation)
Updating Windows

Problem started after I bought a SSD and install windows on it.

Acer Aspire V5-561G (replaced the original 1TB HDD for a Samsung 850 EVO 500GB)
Intel i7-4500U
AMD Radeon R7 M265 2GB dedicated VRAM

If i run powercfg it says that sleep mode S3, Hybrid, Fast boot and Hibernate is available, but S2 and S3 are not available because "the firmware of the system doesn't allow it" (translated from spanish).
Now, using dumppo on cmd as administrator: dumppo admin it says: Min sleep state......Smiley Frustrated1So, as I read on a website, if that happened (having the min sleep state as S1) that might be the problem, so I changed it to S3 with dumppo admin minsleep=s3 After that dumppo said Min sleep state......But after a restart it changed to s1 again.

PD: If I set minsleep=s3 it works!!! But it stills changes after restart. And I would love to know the origin of this problem.
PD2: now minsleep=s3 doesn't work. This problem is kinda random.

Clarification Request
Formatting needs clarification.

What I usually do is use the OS the laptop comes with since a clean install today is too much work.

Thanks, but how

How can I do this on a new drive?

- Collapse -
I rarely do anymore.

I use the OS the machine comes with or order restore media if I forgot to make them.

But why bother with sleep? Just let it hibernate. Works great on my laptop and yes, I have the SSD.

I would if I could

I can't hibernate. And now I can't even turn it off.

So the OS is blown?

Time to go back to stock. Painful but I've seen too many Windows that are blown up with registry tweeks and cleaners. At some point we call it and use the factory issued OS to do over.

I'm having pretty good luck with Windows 10 but still having to go old school for BIOS and drivers just like it was 1995.

How to

I'm thinking in installing old HDD back, do factory reset, connect new SSD via USB-SATA Cable, migrate reseted HDD to SSD with Samsung Data Migration (or similar software), get old HDD out and put the new SSD back in.

Does that have sense?

I do that weekly it seems.

Folks are migrating to SSD a lot more now. So we clone the drive (migrate?) with tools like Apricom and others.

Windows 10

I'll update some drivers and test if problem still there, i'll give a try to windows 10. If non of those options works, i'll try doing a factory reset in the old HDD and clone it to the new SSD, i'll let you know the result.

It worked

Updating to Windows 10 seems to be the solution (weird...)
But this problem sometimes come back, so I'll let you know tomorrow.

Windows 10 was the solution for me.
