Iam not sure that below mentioned scenarios will resolve this issue, but you can give it a try..
1. First remove the card , then try to boot . Check if its working or not . If its giving display & booting properly. Then flash the latest BIOS available i.e 0113 . Follow BIOS flashing procedure as mentioned below.
If your system’s current BIOS version is 0048 or earlier, you must
first update to version 0099 before updating to 0109 or later.
BIOS version 0099 added support for Microsoft Windows 8*. Due to
structural changes in this BIOS version, once a board has been
converted to this version or later, it will no longer be possible to
downgrade the BIOS to version 0048 or earlier. Attempting a BIOS
downgrade to a previous version may fail – the board BIOS will remain
at its current version.
Now .. install your RAID card .. hope its working ..
