Hi, my old motherboard died so I just bought a new one as well as the corresponding memory. I just installed everything and everything seems to be connected correctly, but when i start the computer all goes well and then i get this screen that tells me to choose either safe mode, safe mode networking, or start windows normally. I have tried all of them and after a choose one the windows loading screen pops up for less than a second and then a blue screen appears saying something is wrong with my hard drive or my hard drive controller. What is the problem? Thank you SO much for your help!!
