my macbook 2008 will not come on the light in the front hasnt came on and i conected the power on inside of computer and nothing please help

See if you can zap pram and reset smc first... how to do that can be found on the support part of apple’s website or use google. You may have to reinstall the OS from the original DVD, if you still have it. Hold down the ‘c’ key on reboot and put the DVD into the drive, then follow instructions.

Well, it’s a start anyways
