OK - that update could have failed if Yosefix hadn't been installed first - some updates worked OK - some didn't. Try resetting the nvram as described above first?
Got a tip for us?

Yes it was Ok , and after i instaled updates , the screen flashed , and i restarted and won't boot anymore ..
Just to be clear about what happened...
Did you patch the version of Yosemite yourself or was it the pre-patched download listed on here?
If already running 10.10.4 the way you appear to have installed is unnecessary. The pre-patched version is older than 10.10.4 and needs Yosefix installing before updating further.
Did you then try to update this via the Mac App Store?
If so, I would reinstall the pre-patched version followed by Yosefix BEFORE trying to update further. Once Yosefix is installed as instructed you can then add further updates via the Mac App store.
My guess is you downgraded from the installed version and if Yosefix had been installed by the ebay seller, you removed it with the Pre-patched install.
Good Luck.

now i dowloaded de unpadhed version (with my laptop macbook pro) from the app store, and i use the SFSOT beta to make usb installer , let's see if is working.
If you already have the pre-patched installer, use that to install 10.10.0. Then immediately install the PikeYoseFix and reboot twice. Then run your updates through the App Store.
NO. I didn't mean any criticism of your English - I meant I agree with what Hennesie said. Reinstalling the earlier of version of OS X you have on the USB and then as described is exactly what I did and it works on the same Mac as yours.
Your English is far better than my Romanian

That doesn't look good - Is this happening under all versions of the OS?
Have you tried reseating the graphic card or removing and blasting it with compressed air? My guess would be that is graphic card related but I am sure others here will be able to advise. Have you checked monitor and leads are OK?

I dont know how is the procedure reseting a videocard, it was taking off, but it's clean, it not nesessery to clean up, not
dirty
I don't know which card it is exactly but if it is a genuine Apple 8800GT it could be faulty. They were not well made.
Can you connect the monitor to another computer with a different cable to check it isn't the monitor or cable. Or connect the Mac to another monitor to try to eliminate causes.
Have you reinstalled the pre-patched Yosemite yet? You said it was working before upgrading to 10.10.5 so worth trying. The screen flash and failure to install may not be the same problem.
