Pc become slower after motherboard changed

[blurr007]

I bought this laptop Asus G53SW-A1, everything run smoothly before I send to Asus Center and they changed my motherboard to a new one because of Motherboard failure(they said). I already reinstall all the drivers and everything are up to date including my Graphic Driver. The problem is, whenever I played games, it started to lag and it is not smooth like before. I already try to change my Power to High Performance, and it just the same. Can Anybody help ?

Intel Core i7 2630QM
RAM 8gb (4x2)
Nvidia Geforce GTX 460M

have you tried a registry cleaner like the one found on CCleaner?
Have you done a fresh install of the OS?

Is it a must to have a fresh install of the OS, from from I heard about, as long as u already reinstall the drivers, it should be fine.

check your temps, maybe they didnt seat a heatsink correctly.

Honestly, I don't know... in the 15+ years that I have done computer work I have never had to replace a motherboard with the same board. I have had systems where the mobo is DOA and get a replacement... but because it was DOA I didn't exactly have the OS loaded.
