Hackintosh suddenly won't turn on. Help!!!

Thanks BeatlesFan5858. Turns out it was the psu. Switched it for a CS550m (was a cx750m before) and it has fixed the issue. As a weird reward, my audio is also now working! Happy days!

This exact same scenario happened to me the other day. Nothing seemed to work. Removing the onboard battery and then resetting the CMOS finally did the trick.

Thanks for this. Finally got everything working perfectly and then... nothing. Removing and replacing the battery did the trick.
