|It sounds like your system is really messed up. Maybe the best thing to do is to format and re-install. |
Before you do that you may be able to copy your personal files using a live version of Linux, that runs totally from a CDR or DVDR. One that I am familiar with is Knoppix.
Once you make the disk you boot to it and it can configure all your hardware, including external drives and network drives. I wouldn't recommend using a network drive but a USB external hard drive would be good.
Before using the copied files you could scan them for viruses, etc.
Google for Knoppix to find a download. Burn it to disk and then boot to that Knoppix disk. Read all the screens so you configure your hardware. Then recover your files.
