Sorry, I don't check this much. Can you elaborate on the problem and let me know your PC's specs?

I got you shug. Your computer simply isn't powerful enough.
You need to defrag your harddrive. Clean drivers, delete all unused and unneeded applications then reboot after every step.
if it still lags after this your device does not have strong enough processor and you need to buy and install a new one. I recommend going to Newegg for this.
