We need a more detailed explanation of what's happening. Are there any beeps coming from the tower? Have you made any hardware changes or moved the system from one area of your house to another? Does anything appear on the monitor at all?

BTW, calling a computer a CPU annoys the heck out of most of us. THIS is a CPU. Please post your complete system specs or if it's an OEM system (Dell, Gateway, HP, etc), post the model & model number.

No there is no beeps at all, I remove RAM clean it it and then put it back.
The monitor say: "Entering power save mode" and then turns off .

Still no specs or model number?

"I remove RAM clean it it and then put it back"

Did you do this before or after the problem? If it was before, I suspect the RAM wasn't reinstalled correctly.

Tap F8 while booting then select Safe Mode from the menu. See it boots OK from there - desktop will look a little unusual if it arrives.

Always pop back and let us know the outcome - thanks

There'd usually be some beeps if it was just a ram problem so if the problem started after you played with the ram sticks then likely something else is wrong, or something in addition to a ram problem. Maybe you accidently did some damage while you were inside the case.

If you get any kind of normal posting screen then try safe mode as Derek suggests.

If you just get the monitor message about power save mode and the problem started prior to your cleaning the ram sticks then it's usually the motherboard, power supply or both. Check my # 3 here:

Not all the suggestions there may apply to your situation.
