i have a 60 gig ps3 and I usually leave it on for long periods of time like a few days at a time. well the other day i get home from work and it is on then I go play call of duty 4 and the ps3 is not on, so i press the power button and it goes on then the colors on the led went from green to yellow then to red then nothing.

now it wont even turn on at all. The warrenty on it is void cause i opened it when i first got it cause i wanted to play my backup ps2 games. So, do you think this could be a psu problem or motherboard fried? Any input at all on this would be greatly appreciated.
