everytime i try to do a regular boot, it gives me a blue screen (following the green progress bar)

but it boots perfectly fine to safe mode. but i have no idea what the problem with my machine is or what i can do to solve the problem. can someone at least point me in the right direction? i really have no clue what to do now...

Please tell us the error message presented first... it's down the bottom of the BSOD. Is it just a STOP error with random codes, or does it also list a DLL, SYS or DRV file? If so, tell us this file it mentions. If it mentions no problem, it could be impossible/unrealistic to fix and reinstalling Windows would probably be easier and quicker.
