resently occasionaly i have been getting a very strange type of lagg... used to be completely fine the only thing that has changed since then is a new keyboard.. yeah i know right.. how can it be that? but when the lagg happens i will open up a game fine, but my cursor will be really juddery.. say i was playing e.g. counterstrike source. i can join a server fine.. join a team blah.. if i stand still or use WASD to move its fine!! 100-150 fps!! but as soon as i move the mouse ITS A SLIDESHOW!!! i first thought i could only get rid of it by restarting my comp. but i tried unplugging keyboard and putting it back in, and the lag went away.... (for the time being) sooooo something to do with keyboard? mobo? my specs Mobo- p5n-d gfx card - 8600gt processor- e8400 KEYBOARD- Roccat Arvo Mouse- Logitech g500 (hmmmm wait a sec both my mouse and keyboard use 1000hz polling rate i have heard this can sometimes play havok with stuff duno tho :S) 3gigs ram Windows 7 32bit Asus Xonar dx If you need more info just ask
