I have a feeling this still won't solve the problem, but at least i'll be able to rule the ps out.
If anyone else has anything to add to this, please feel free to.
I used an Enermax Liberty 500w with my build, and then swapped it out for a Liberty 620. Both worked fine, so in my case it definately wasn't the power supply. Just out of curiosity, you do have 3 power connectors hooked up to the mobo right? The 20, the 4 pin extension to make it 24, and then another 4 pin on the far side of the mobo? Did you hook in an extra 4 pin on the far side of the mobo just for the sake of trying? This second 4 pin might be covered up with tape or something.
I sure did try that.I hooked up the extra 4 pin 12v by the cpu and that didn't make any difference whatsoever.I also forgot to mention that i tried a P4 640 3.4 and some older ddr2 533mz in the board to see if it could have been a cpu/memory issue and still couldn't get the board to post.
The thing that concerns me is that i know of at least 2 others that are having the same exact issue as myself with similar equipment and the same board and they also can't get the board to post.An Asus tech said something about the P5B Deluxe's bios being housed on the Southbridge chip and that it was causing them some strange problems(before being updated by a newer bios patch of course.
Now that you mentioned that your Enermax Liberty works just fine with your board, it makes me feel better about mine.The new P5B Deluxe will be here tomorrow and i'm still not sure what i may try first.
So many of us are having the exact same problem with both versions of the P5B (all with only slightly different equipment) that i am starting to think the problem might be either
A. something the same on the boards is defective which will not allow the boards to even post or B. maybe a combination of components we are using is causing a compatibility problem.
As before. Any and all advice would be appreciated.
***Just found out a few things that may be the culprit.***
1. Some of the P5B/Deluxe boards shipped with a bios version that simply don't support the Conroe processors those of us expiriencing the "no P5B posting" problem have.The only way to correct this is to use an older cpu and then update the bios as soon as you are done OS installation.That will solve the Conroe non compatibility problem.I am still not 100% this is behind the "no post" problem alot of us are having.
2.The P5B/Deluxe is extremely picky, especially with newer memory/high end memory.Some people in the "Newegg P5B Deluxe review thread" have reprted expiriencing a similar problem with not being able to their P5B/Deluxe's to post using most higher end memory types,especially higher end OCZ.Using older ddr2 memory to get through installation seemed to do the trick.As soon as the board bios was updated to the newest version, they then reinstalled the high end memory and the board worked fine.
While i thought that might be my problem, i am using Corsair XMS2 twin2x2048-6400c4 and obviously still can't get my board to post.I tried some older PQI ddr2 533mz and that didn't work either,so i am still without a definite solution.
I hope the above examples can help someone.If it solves your "no post" problem, please let us know here.
