Help needed with Sabertooth P67 POST failure

post #1 of 6
Thread Starter 
Hi, first time poster here, looking for some advice from the vast pool of knowledge available in this community.

I'm building a new PC with the aim to start watercooling biggrin.gif. I managed to get everything installed, running perfectly, apart from the double POST at cold boot issue which seems to affect some P67 MB's. I followed some advice to solve this by enabling "Power on by PCIe" in the bios, and ever since doing this I cannot get past the POST on start-up. The MB shows it is getting hung up at the GPU (red LED stays lit), so I cannot even get into the bios again to make any changes. Tried clearing the Cmos several times using the onboard jumper. Tried replacing GPU with another which I know is working. Nothing seems to make any difference. Trying not to accept that I might be sitting on a useless pile of expensive components! Any help and advice welcome! smile.gif

Specs:

Core i7 2600k 3.4 GHz
ASUS Sabertooth P67 B*
XFX HD 6870
8GB Corsair Vengeance
Corsair AX650W
120 GB Intel 520 SSD
Corsair 650D Case

Bump, cant say ive heard of this problem unfortunately, but Id hate to see someone with a brand new pc and being unable to use it. Hopefully someone else will see this thread and have a solution for this problem.

mmm I have the same board as you and cant say I've ever had this problem.
All i can suggest is maybe disconnect everything and try again (if in doubt start again! tongue.gif )
maybe take the battery out when everything is disconnected, basically start completely from scratch.
hopefully good...

Thanks for the reply, I'll start again and see how it goes. Fortunately I hadn't begun what was looking like a big job of cable management! I guess I'm facing a couple of questions now:
  1. Could the POST failure have been caused by changes I made in the BIOS to a functioning system? (And consequently, wouldn't clearing the CMOS resolve this?)
  2. If the POST fails at the VGA part of the process, does that indicate that the other components (CPU and RAM) are not the problem?
  3. Since the system was working (I even ran POST checks before installation), what else could have caused the problem?

Some further information which led to the problem:
  1. I had just finished installing Windows updates.
  2. I Had just connected an older HDD from another computer (this was recognised in Windows but I had noticed it wasn't recognised in the BIOS).
  3. I had just changed the boot priority to SDD at 1st

Hope a rebuild will solve this, and that it isn't a faulty mobo.

@$ilent Thanks for the bump smile.gif I've been collecting the parts for this build for a long time, researching everything late into the evenings! Going from the excitement of finally installing everything and starting to customise my system to failure at the most basic level sucks!thumbsdownsmileyanim.gif

OK. Took everything apart, thermal shroud off, battery out, cpu out, and started from the beginning, but the problem still persists. Before I look at returning components, is there any way to be sure this is a mobo fault and not cpu or ram? Tried a working gpu in both lanes and same problem. POST cycles through ram check without problem. And more confusingly, everything was working for about 6 hours till this!
