My mouse seems to lag or freeze every time I launch an application after reformatting my hard drive, or move big files folder to different folder or even just surfing the net switching pages to pages. I was wondering if this has something to do with missing drivers. I believe I have reinstalled all the basic drivers I need such as video and audio drivers, but what could be the possible cause my new reformatted machine tend to lag or freeze for 5 to 45 seconds. I've never seen like these before. It's getting annoying.
