AI7 - POST code digit screen was incorrupted

I have bought this AI7, after install complete, all things are stable but the digital digit screen of POST (Nearly the nGuru Chip) was incorrupted. I can't read the digits in it for the sample (See the attachment)... What the problems are being run in my system? What's wrong? Please help me to fix the problem .

P.S. All things are normal and with the newest Bios (the Older Bios is the same problem).

Done! Thanks!

what number is that as i cant tell.

is that a 26?
