well yup i cant do them after i turn my computer on. well i think i did a registry tweak which supposed to shutdown my computer faster. i dunno if thats the case. well actually it first started that if i wanted to shutdown, i have to go start > shutdown > shutdown. and do this twice then it works. same for restarting a computer. now it doesnt even work. im thinking a registry fix or somesort. i even tried shutdown -r or shutdown -s doesnt work either.HELPP..i dont wnat to power off manually, seems like im killling my computer.
