So one day I restart my computer and it doesn't restart and it gives me a message saying windows did not properly start last time. the choices they give me are boot in safe mode, boot normally, and boot last good conifguration. None of those boot it, it just does the same thing every time, which is goes to the windows loading screen for 1 second then restarts and goes to the error again. Then, I ran a hard drive test and it said my hard drive failed so I bought a new hard drive and installed windows on there and it still gives me the error and restarting issues. BTW, my initial os was windows xp when it started happening, then i installed (and formatted) windows 98 on my old and new hard drive and it kept coming up so its not a os or hd problem apparantly. What is the problem? Thanks.
