i recently got a new harddrive and have been having some problems with it. I've made sure to click DMA in device manager etc. but my computer continously lags whenever i try to do anything. Like even load webpages and just open applications, is this the harddrive that is doing it or a problem with the board or anything else. If it is important i had my cpu oc'd for about a year and i just took it down to stock to see if that would help, it didnt. if anyone knows that would be great, thanks.
