I wanted to upgrade my desktop P5E3 Premium MOBO and Q8200 processor running Win 7 Pro. I reused all the HDD (C, D, G, M) and burners. I installed the P8Z77, i5 3550, 8 Gig RAM, and GTX650 Ti video. POST single beep was OK, C:\ is recognized but will not open and Windows goes into repair mode. Tried to boot with only C: connected, and it shows C:\, D:\, and X:\. What is that all about?
