Hey guys,
I got a problem. Today i bought 2 ASUS HD7870's for my new pc.
Moba: Asrock z77 permormance
CPU: Intel 3770K
RAM: Corsair Vengeance 8gb
Storage: 1tb HDD and 200Gb SSD
DVD drive
OCZ Fatality 1000Watt PSU
2 Asus HD7870

I got some strange problems with booting it up.
Situations:
Only GPU 1 installed ---> post
Only GPU 2 installed ---> post
Both GPUs installed ---> no post
-With keyboard ---> A2 error
-Without Keyboard ---> D7 error.
-All 3 crossfire bridges give the same problem.

I dont know what to do, can somebody help me out?
 
Solution
A2... A2... reminds me of something to do with hard drives. Go into the bios when it boots, and make sure to set the right harddrive to boot. It might change because you've put another graphics card in.
