Hello StalkeR
Thanks for your help,i thought this repair would be easy to fix!
The only way i can fix this is to use what i have on my cpu.
"Acronis" TrueImage" In this case i had to go back 4 months!
PS
I have tried everything to fix this. But i feel that the problem happen when i up dated my Nviaia 240 card.
