when i say that the video card stay's like that i meant it stays in 100% and it doesen't drop to normal so the system can start..it's like it's jammed or something :p

Welcome to the forums!

The bios is refusing the overclock.
You will have to find more stable settings.
Run Prime95 for 6-24 hours to check for stability.

Vcore seems high at 1.5v.
Try lowering it if you can.
