Apologies for the delay in replying.I have filled out my system specs.The OCZ has no drivers per say,it only has a program where you can change profiles,DPI level and USB report rate.I thought it may have been because of the report rate.Even though i use the same settings in xp and have no problems but it still occurs.I have noticed lots of problems in terms of usb,sometimes my usb wireless starts with windows with an error.I have to disable and enable it so it will work.And sometimes my mouse freezes also when i boot into windows.I again need to log off with my keyboard for it to start again or unplug it and plug it back in.Again,absolute no problems with Xp.
