@ramy123 - Well darn, The GPU failed, Apple had some faulty GPUs in the 21.5 & 27" Mid 2011-iMacs, MacBook Pros, and Mac Minis.

You would need to buy a new MXM GPU and Replace it,

Keep in mind It Can be very tedious, You won't get a boot screen unfortunately. ;-[

Guide: iMac Intel 21.5" EMC 2428 GPU Heat Sink Replacement
Part: MXM GPU

(Please note: It will fail again!)

Good Luck!

Feel free to comment if you have any questions.
