my computer froze today creating this whole problem. i was playing cod4 on medium-low settings while listening to itunes and after playing for about 30-45 mins it froze. so i hit the restart button. it loads says there is a .sys or .exe problem. i fixed that using the windows xp cd i own. also i just arranged my case from ATX to bATX which was quite fun and i did it after the comp froze bc i was bored and then i fixed the error that kept on coming up. now it turns on loads to when it says windows xp and the blue bar scrolls across part of the screen. but then it doesnt load to the choose account screen. i have 2 accounts one for me and my bro when he plays some games. he only played on it once so far and that was a while ago so i dont think he did it and he only played halo. do i need to try to get in on safe mode and delete the accounts so there is only one then make them again? the screen just goes black. WHAT DO I DO?!?!?!?!??!
