Yeah, I would go ahead and do a clean install using a bare bones windows 7 disk and then install the latest drivers one by one. Here what i did to clean up some issues i was having (credit to brodyboy)
Download and burn your own windows 7 disk, download all the driver before hand and put on a usb (makes install quicker, and its a bitch trying to download drivers w/o your wifi card installed lol) theres links to download and latest drivers here:
