Lenovo y50 blank screen automatic startup repair?

Got a new Lenovo y50. When i started the computer it seemed fine. Then I installed chrome after i ran auto setup. But then i were watching some youtube and were customizing stuff like the startup screen. But then it got slow and irritating. I went for a reboot, since I've heard new computers will take a couple of reboots to sort of warmup, and then, out of nothing it says "startup repair", and when its done loading, its just completely blank. Left it there for 30min and still nothing happened. I've also tried load optimized defaults i'm BIOS, but with no sucess. Do you guys suggest, that I return it?
