I may be wrong here but it sounds like one of two things to me. One your hard drive is failing or more likely you picked up a bad virus.

Run CHKDSK trough Command Prompt

1. Open an elevated Command Prompt (Press the Windows + X button at the same time, then choose Command Prompt (Admin))

2. Type the following command, and replace the X with the drive letter you wish to scan: “CHKDSK X:”, we suggest you use “CHKDSK X: /F”, only then it can correct errors.

3. Hit the enter key, Command Prompt will now start CHKDSK.

To check for viruses do the Security Tango:

Nick is from Rochester NY and on his weekly radio help show says this is still the best method to rid yourself of those bad things.

Good luck and I hope this helps.

Whenever I get something stuck in the back of my throat, I dislodge it by drinking a beer.
It's called the Heineken Maneuver.
