I was downloading files today and leave my computer alone. After I got home, it freezed up. And I restarted my computer. My Windows XP cannot start up. I think my problem is that the available space on my harddrive is not enough for windows to start. So Can anyone teach me how to delete files thr MS-DOS. I tried to gain access to C drive thr DOS, but command returns "not ready to read C", what does it mean? DOes it mean that my harddrive is completely dead? Please!!!!help me out! I'll wait here for help! thank you very much!!!!
