Hi all,

I just finished my first PC build:
Asrock Z77 Extreme4
Intel i5 3570k
EVGA 670 FTW
16GB Corsair Vengeance RAM
Corsair HX750W 80+Gold PSU
Samsung 840 Pro SSD 256 GB

I'm trying to install windows 7. The system has to problem booting to the UEFI. It even finished the initial install of windows but when it restarts automatically after the first series it crashes and says it cant load windows. I've checked all the SATA power and data cables and they are all fine. I'm not sure if this is relevant but the MoBo debug codes flash 4f 62 99 and finally A2. It doesn't hang up on any of them though.
Any suggestions?

run MEMTEST before any further troubleshooting.

Your memory could be defective or not setup properly in the BIOS.

I forgot to mention in my first post that I had tried memtest and everything came back clean. The bios is also recognizing all 16gb of ram as well as everything else installed. Any other suggestions?

Other:
1) Make sure the SATA connection is on AHCI
2) Try a DIFFERENT COLOR of SATA connection (usually use the best one like INTEL SATA3)
3) Try a different SSD or HDD
4) Try installing Ubuntu (last resort)
