I finished building my new pc 5 hours ago, it contains:
Intel Core i7 3770k
Asrock Z77 Extreme 4
Corsair Vengeance 16gb ram kit
Sandisk 256gb ssd
Nvidia GTX 670 Windforce OC
Also this isnt the first pc i built.
Now as i was done building, i tried to start it up, fans start running, also cpu-fan, lights go on, but no beep from the mobo.
So i did the standard stuff, trying with only one ram installed, tried differenct ram slots, checked cables, took out the ssd, CMOS reset.
Nothing worked, so i took my mobo out of the case again and "breadborded"(i think its called like this) it, just cpu and cpu fan connected. It started up, but again no beep.
So i started searching in serveral forums on serveral pages, tried their solutions which were for ex :
-attaching keyboard via ps2
Nothing worked, and those 2 numbers on the mobo, dr debug, told me continuesly the error codes a2/a6/b4/d7.
Then i read somewhere that i need a newer bios version, but on asrock's page it says that my cpu is supported by the default bios version.
So now im wondering waht to do. Sadly got no old 1155 socket intel cpu lyin around to upgrade the bios version.
Contacting asrock so they send me a new bios battery would take pretty long time, since they have vacs currently.
All help is appreciated
Thanks in advance
I assume that you connected both the 24-pin (MAIN) and 8-pin (CPU) power to the MOBO and in particular 'CPU' power and not some other connector. Most GTX 670's are 2 x 6-pin PCIe power so that must be connected. For sometime most MOBO's and Cases no longer include a 'MOBO Speaker' so you won't hear beeps.
If Breadboarding then for now don't connect the GPU and only connect the onboard video to your monitor; make sure the monitor's input and MOBO's output are the same type. If needed then try to Clear CMOS and see if that helps - unplug the PSU for 5 minutes, move the CMOS Jumper (or press the Clr CMOS button) for 5+ seconds, move the CMOS Jumper to it's default position, plug the PSU back in and try again; nice video - http://www.youtube.com/watch?v=rdHH9KrceR0
