FPS drop after re installing windows

[nupian]

So i replaced my hdd and had to install clean slate windows, which i did. Then i installed all the driver that came with the laptop (ASUS). Now, before when i play games, i would get 30-50 fps, now even when playing just DOTA2 on lowest setting, i get only 5 fps even when nothing is happening on the map. I upgraded my ram to 8GB when i replaced my HDD. I can't figure out what to do and any help would be appreciated. I'm using windows 7 64 bit, same as before

More than likely you need to install your video driver. What is the model number of your ASUS laptop?

i did install it with the driver cd that came with the laptop. Asus A53S.

Try installing the driver from Nvidia's site. The one for your laptop is GE Force GT 540M:
