Try following the 8 Steps to Troubleshooting Any PS3 Issue.

With your PS3 turned off, press and hold the Power button on the front of the PS3 for about 10 seconds (the system will beep as normal as it starts up but after 7-10 seconds it will beep again). The video settings should now be reverted. Doing this will also reset any theme settings. try this? seems to fix alot of issues.

Confirm the gamepad is working and not short-circuited, any other cables connecting the device

this is the ps3 equivilent of the xbox360s red ring of death error, sorry to tell you but that means a serious system error has killed your ps3 its unfixable and you will have to send it off for a replacement

it is fried and needs repairs if you break the seal by trying it yourself you void the warrany

It's likely that you are a victim of poor design. Your problem is referred to as the Yellow Light of Death or YLOD.

This is called a System Error. It is about the same as the Xjunks ring of death. You need to call Sony if you haven't broken your seal yet.
