I need help please and fast.
The boot hard drive may be bad...
Try booting into Safe Mode
tap F8 once/second until you get a B&W screen - - chose Safe Boot
No that doesnt work. I had it normal a few days ago but then one day I went on it, it was on classic mode
?? Do you mean it can not boot into Safe Mode? If so, you have real issues. I did not expect it to solve your symptom by itself.
it goes in safe mode, but logon is still in classic mode
