So I started putting together my new SB build. Starting with assembling outside the case to make sure everything work properly. I've got my 2500K mounted on the MSI P67A-G45 mobo, ram seated (in second channel, first was blocked by the CPU cooler), and 24 and 8 pin power plugged in. When i turned it on i was at first getting two quiet beeps (apparently a successful POST for this board), and then a high pitched short beep followed by 5 louder ones. Couldn't find anything about the code online, so i tried installing my 5870 to see if I'm getting visual output. The first time I tried this i got no beeps; nothing. Tried again and got jsut two beeps, which is apparently normal for a good POST on this board, but then i was getting no screen output. My keyboard lights even lit up, I just couldn't see anything. Afterwards trying again I once again got no beeps. Any idea what might be going badly? I'm using the included (with the GPU) mini-DP to DVI adapter, and then connected to my monitor's DVI port.
EDIT:
Found something about the codes, but i'm not sure if it's for this board specifically.
POST BIOS beep codes
* 1 - Memory refresh timer error
* 2 - Parity error in base memory (first 64 KiB block)
* 3 - Base memory read/write test error
* 4 - Mother board timer not operational (check all PSU to MB connectors seated)
* 5 - Processor failure
* 6 - 8042 Gate A20 test error (cannot switch to protected mode)
* 7 - General exception error (processor exception interrupt error)
* 8 - Display memory error (system video adapter)
* 9 - AMI BIOS ROM checksum error
* 10 - CMOS shutdown register read/write error
* 11 - Cache memory test failed
* 12 - Mother board does not detect a RAM module (continuous beeping)
