Input lag

I've recently switched to windows, and.. eh.

I must say, it's awesome, but it has its flaws. 

It seems most times when I log on, whatever I type or press on my keyboard takes a few seconds to follow through. I didn't think I would be getting stuff like this with my new computer, but oh well. 

My usual solution is to start task manager, and end whatever looks to be lagging, once I do that, It seems to fix up a bit.

 

FastBoot is turned on by default, and I'm not sure if that might be the problem? My motherboard and OS support it.

 

Gah, it's annoying, but I just want to figure out how to stop it from happening.

this wouldn't by chance be in internet explorer

this is anywhere on the OS

you have input lag running windows on your imac? ;d

Any lag on your mouse?

What KB are you using and what connection type?

Tried flashing the BIOS?

Tried flashing the KB (if it suports)?
