Hey everyone,
So today I made several upgrades to my PC, but now it won't boot to windows. I can only use the on-board graphics of my new motherboard to access the Bios. I got a new case (Corsair 750D), a new motherboard (MSI Z77 MPower) and a new CPU water cooler (Corsair H100i). I have my Windows 7 installed on my SSD and in the Bios I set my PC to boot to that SSD, but it won't work. What should I do? Any help is much appreciated!
