Hi

Bought an used maximus v formula from a hardware store in good condition with all the parts in the box.
Have moved over all the hardware from my "old" pc and when I try to boot it up to install operating system I get a short bios beep and then almost instantly an A2 error code.

Have double checked and the disc and cables works fine, have also check so they all are plugged in but so far nothing seems to work, reading around here I did stumble across "http://rog.asus.com/forum/showthread.php?21823-Maximus-V-not-booting-with-mPCIe-card-plugged-in-Try... and yes the mpcie card is installed but is behind a fat radiator but is that the best action to do right now, try and unplug it for now and then try and reattach it when I've installed the operating system?

Hardware:
maximus v formula
i5 2500k using a corsair h70 to keep it cold
2 sandisc ultra II 240gb to be raid 0 for operatingsystem drive
1 seagate 2tb harddrive for movies/games that don't primarly need fast loading speed, later I'll buy a small msata ssd to work as cache for the harddrive. As soon as I've the pc is up and runing I will scheduel weekly backups to the harddrive and an extra copy to my nas runing four 2tb drives in raid 5 to secure my data vs the risk with raid 0 on main drive.
have 1 corsair xms 4gb in dimslot 1, will put in a total of 4x4gb when I know the pc is good to go.
xonar phoebus sound card, maybe a little overkill with the motherboards own sound but have fallen for it after using it all this time 🙂
asus 6870 directcu is doing all the graphics 🙂
and chieftech nitro 850watt bps-850 is making sure everything gets enough power 🙂

Is using a wooden wall cabinet as a case and a motherboardtray from lian li so I'm not using any of the front I/O functions. Have plugged in the q-connector and a basic 4pin speaker but nothing else.

So after this long wall of text post, is the next step I should take in troubleshooting simply to remove the mpcie as I wrote in the beggining of this post? Have already mounted and dissmounted the radiator 3 or 4 times and don't really want again unless I really have to, that's why I'm asking.

Thanks in advance!

update: have unplugged the mpcie card, graphics card and sound card for now.
Then I got error code B6 and cleared cmos and now I finally get something on the screen, sort of. Stuck at rog post with the text "press delete for bios" but nothing happends when hitting delete multiple times and the error led displays A2 again.
