my [Toshba Satellite] computer was moving rather slugishly, so i pressed ctrl-alt-del, and restarted. i walked away for a few minutes, came back, it was on a blank screen. i walked away, came back, here was a blank screen w/ a moveable cursor. i walked away came back later, it was still there.

i restarted, tried repairing under system error recovery. it brings me to the same screen w/ the cursor after the loading bar screen. i try to restart windows normally at the system error recovery scren. it gos to the loading screen, stays for a couple minutes, flashes a blue screen with typing on it [for every bit of 5 milliseconds] and goes back to the inital boot screen [the one before system error recovery].

so i press F8 to get to advanced boot options. ive tried everything there except for debug mode. everything gets stuc and brings me back to th initial boot screen before the system error recovery screen. during my attempt at booting thru safe mode, it gets stuck trying to load, or after loading, crcdisk.sys. it then goes back to that screen. i cat get into anywhere to help my machine b/c it brings me back to that screen.

apparently i need help.
any is much appreciated.
