This is what I would do:
A. Get your data saved to another hard drive (e.g., 1TB external USB, $60 shipped). Or buy a new primary one.
B. Install Windows from scratch. Unless you use a new primary drive, overwrite everything on that existing hard drive
C. Install a good virus program. Malwarebytes is good to have alongside.
D. Copy the data back
E. Enjoy your "new" system
That idiot brake light could be low brake level fluid, a stuck floater, or even a loose wire in that circuit. Could also have to do with the ABS system if you have one.
Nice lookin hard drive for the price. Too bad it isn't made to fit my "portable media drive" in the front of my tower. Gunna search the site for one. Windows vista disc has a recovery something or other on it. Just gotta find it.
**So much for ading the site to my favorits folders. Can't add anymore since I saved bleepingcomputer.com on temp desk top. Another on the to do list...makes me feel like Samuel Jackson's character in Jurassic Park. "Please! Dammit! I hate this hacker crap!".
