Hmm, every time I go to restart my PC it posts and everything, then gets to the WinXp loading screen for about 1 second, then goes to a blue screen that says (UNMOUNTABLE_BOOT_VOLUME) and then a bunch of stuff about restarting or going into safe mode. At the bottom there is technical info: something like 0x00000ed (0x00000, 0x00000df, 0x00000) If these numbers are important i will write them down next time. I'm just wondering what is causing the problem, so i can replace whatever it is and get back to failing school... Thanks
