I downloaded and ran CCleaner yesterday on my laptop. It was running slowly and I have been trying a lot of different things like ad-aware and spybot. It was working slowly, but still working until I ran CCleaner. I restarted the computer after I ran the program and not it won't go past the black windows screen with the blue scrolling bar (I'm running XP home). I tried starting it with last known good configuration, the same thing happens. I tried safe mode, and a bunch of stuff scrolls down the screen then it just stops and it won't go past a DOS screen. I tried putting in a boot disc and that will not load past the blue screen that says windows is loading setup (or something like that). I've let it wait for a few hours and it just won't go past windows loading in any setting. Does anyone have an idea if my system is recoverable, or did CCleaner kill it? Any help or tips are very much appreciated.
