Okay so I am not very knowledgeable about computers and hardware problems, however I am pretty sure the problem with my computer lies within windows xp. Every time i start up my computer it enters a black and white screen that says "we apologize for the inconvenience, but windows did not start up succesfully. a recent hardware or software change may have caused this...yada yada yada" This started happening when in the middle of reinstalling diablo 2 the computer froze. I have options on the screen to enter safe mode, safemode with networking, safe mode with command prompt, last known configuration and start windowns normally however none of these work. Each time i choose any of them it jsut returns to the same screen. What should I do?
