When i turned on my computer it was going extremely slow. I tried restarting it signed in then it froze then went to a screen with the asus logo and "Prepairing Automatic Repair" after that it goes to a black screen until i turn it off. I don't think its a hardrive problem because i can still see the hard drive in my bios. I have a Asus G750JM. Can anyone help? Also My grandma bought it for me as a gift at bestbuy with a warranty and theres something about this "lemon policy". If i can't fix this problem I will have to bring it to them soo they can fix it (hopefully). But this would be the 4th time i would bring it to them to get it fixed so do they replace it? And with what? I dont think they sell the G750JMs anymore so what would they give me as a replacement? Thanks in advance.
