My Imac 2011 27" I7 not starting

Hey Guys,

I got an 2011 27" I7 Imac which was never having any issues until recently.

The screen started going funny sort of like splitting the Video in half I shut down the system

and after that I tried to restart with only having the Apple Logo coming up with progress bar only loading 30% and then screen goes white and restarts. With the

same progress bar only this time it does not restart and is just stucked on a white screen.

I have successfully formatted the hard drive and was able to run the Imac again for a day then it repeated again.
Now I cannot even go into recovery mode I have done a verify disk before formatting without any errors.

I get error 107 in one of the lines when I hold CMD+V

Now I cannot go into recovery mode or internet recovery.

I got Yosemite Installed with latest updates.

Any Ideas on what it could be?

Thnx Guys

Did you install anti virus software by chance?

No I have not installed any anti virus software this happened also after I formatted the HDD and a Clean Install of Yosemite

See if you can boot in Safe Mode and run Disk Utility from there.

Top left corner of your screen click the Apple  > Shut Down.

After your Mac shuts down, wait 10 seconds, then press the power button.

Immediately after you hear the startup tone, hold down the Shift key. You should press the Shift key as soon as possible after you hear the startup tone, but not before.

Release the Shift key when you see the gray Apple logo and progress indicator.

When you see the desktop, go to /Applications/Utilities then launch Disk Utility. Select the disk on the left then select the First Aid tab. Then click: Verify Disk

(You can't repair the disk from there but at least Disk Utility might provide a clue as to what the problem is.

When you are done, go back to the Apple  menu. From the drop down menu click: Restart

I have done that already before.
I dont thinkl there is anything wrong with the HDD as it verifed the disk without any errors.

I have tried last night to get into Safe mode , Recovery Mode, Verbose Mode without any success.
Any ideas on what to do next?
Should I replace Power Supply? Video Card? or just get a new Motherboard?

Thnx
