I tried installing the USB and other chipset drivers from the hp presario c700 support site. (no change)
I then went into device manager and deleted ALL usb controllers/hubs, and rebooted so they would reinstall. (reinstalled, tested mouse, SAME problem!!!) ok next problem is the USB Root Hub devices I removed all came back as "unknown device" I'm unable to reinstall usb devices correctly at all now that they were removed. I called HP support and they walked through many things including trying to use another user account, and deleting under safemode. (noluck) I'm forced to do a compelte system restore and start from scratch. I dont think it's possible to fix this mess at this point. (oh well, I tried)

GO to HP's website and download the latest drivers (spacificaly USB drivers) for your laptop. Install them and try again.
