Laptop gets unresponsive when getting asleep

[oliverm91]

Whenever I close my laptop or leave it a few minutes it should sleep, but it just turn off the screen.
The led lights (for battery, HDD wich I replaced for an SSD 2 days ago, wireless connection and something else) are still on. Also the fan of the laptop still makes noise. The problem is that if I move the mouse or press any key It doesn't do anything (or at least doesn't turn on the screen) so I have to turn it off the bad way (keeping pressed down the power key).

Interesting fact: if I press fn + f5 wich is the turn-off-screen combination, the screen turns off and immediatly turns on again, in less then half a second.
Interesting fact 2: If I sleep the laptop with the option in the power button while logged in then the problem occurs, but if I do it logged of it works just fine.

Background: Problem occurs after I installed a new storage drive (SSD) and installed Windows 8.1
OS: Windows 8.1 x64
Laptop: Acer Aspire V5-561G (Intel i7-4500U, 8GB RAM DDR3L, AMD R7 M265 2GB, 500GB SSD Samsung EVO)

Hope you can help me.

1) Read the rules, NEVER post twice, especially copy-pasting the same issue
2) Wait for responses, people are willing to help, but it's a volunteer thing so you might not get responses quickly.
3) The issue is with installed software, which is set to start up when you log on (and why logging off lets you sleep it properly). Post a list of installed applications and task manager's details section and we might be able to spot the likely culprit.

Your issue is Samsung Magician. For some reason that software disables sleep. Just remove it from your startup list (in task manager) and it should work.

I removed it from the list, closed the lid, wait a few seconds, open the lid, and the notebook was unresponsive.
Then I uninstalled the software, closed the lid, wait a few seconds, open the lid, and had the same results :/
