Re: Computer wont power up
them sizzling sounds dont sound good. maybe you burned something within the computer which is bad but might not be that. being unplugged for 4 weeks shouldnt do anything whatsoever. i had a pc lying around for 3 years and worked when plugged in. the power supply may also have failed.
