zakmir,
This topic is about the Acer convertible R5-471T Skylake computer. You have the R3-471T Haswell convertible.
Please start a new topic and maybe someone can help you, but you have to provide more details as to exactly what happened. It's not clear what the problem is. For example, do you have the original memory installed in your computer?
Edit: In your case, a BIOS update was probably necessary to fix a memory compatibility issue.
