BSOD after changing to one core, bad system config info

hej bud

I get a bsod on every boot, even in safe mode. changed from 4 cores to 1 through msconfig, restarted, bsod. startup repair can't repair my PC automatically, blah blah blah

last known configuration doesn't work either. can anyone help me get it running again??

edit: i will kiss you right on the asshole if you fix it
