One more check - if you haven't done already. Take off the motherboard from the base plate and remount taking care the standoffs do not short the copper tracks anywhere. Better still if you could use some insulating washers between the standoffs and the MB. If nothing else, use thick paper/card with a center hole punched to pass the screws where the PCB tracks are dangerously close to the fixing holes.
Unless I missed it, have you even tried a different power supply yet? If not and you're haing the same problems after replacing everything else, that would be the next thing to try before going any further.
Good Afternoon all...
First of all I would like to personally thank you all for all your help and support as you've just been wonderful and I appreciate your support you deserve a pat on the back for your support. No I really mean this... although, I do have an answer to all my troubles and believe me it's such a lame excuse but its a viable one.
I've just come off the phone with the suppliers, and spoke to a gentleman who answered all my questions, it was a pleasure to speak to somebody who was singing off the same hymn sheet, so to speak that is. Well it's transpired the cause of the problem is the BIOS needs updating. Although I initially thought of this in the first place it was the first thing I thought of before I started testing to see what the cause of the problem was, although, tiredness got the better of me and I forgot to add the following to the diagnostic tests.
10.0 Checked ASUS website for BIOS update, Crosshair V Formula 0813 BIOS 07/10/2011 was the release date which coincides with the release of the AMD Bulldozer 8 Core CPU.
10.1 Updated BIOS now -
If I was already an AMD user I'd be laughing because all I need to do is basically put in an AMD AM3 and the board will boot without any problems. update the BIOS which I have ready on a pen drive reboot and check the BIOS is up to date. Then power down and remove the CPU and then put the new one back in again and it will be working.
It's a bit naughty of ASUS to sell a motherboard which is AM3+ FX ready which it's clear to me that it's bl***y not because if it was then, myself and other people who have purchased this motherboard wouldn't be in this position in the first place. Am I p****d, dam right I am.
This is a completely new build, okay granted I'm using the same PSU because it's only 2 years old in perfect working order. it's not a cheep PSU either it was expensive. So the bottom line here is.
If you get anybody else that has purchased an ASUS Crosshair V Formula/Thunderbolt or the ASUS Crosshair V Formula and they are unable to boot their system, then they need to update the BIOS to Crosshair V Formula 0813 all you need to do if you are already an AMD user then just install you AM3 CPU and boot the system and then update the BIOS and then re-install the new CPU and then it should work.
I've been a customer of ASUS for over 12 years now and this is the first time I have ever come across this. You could say it's luck; although, In my view I think ASUS has hurt their reputation with this because I'm not the only person with the same problem. My suppliers have dealt with a few other people, and ASUS has advised them to advise their customers. "If they are already AMD AM3 users then they need to update the BIOS before installing the new AMD FX 6100 or 8100 AM3+ CPU because they have made changes to the CPU support within their new BIOS update."
I can understand you being peeved having gone through all the checking and rechecking. I wish I'd seen this thread earlier. The only time I had a board that would take a CPU upgrade it was to go from a Pentium II 350 to a Pentium III 600, and that did require getting a BIOS update from Asus first. Sometimes it's a pain working with a very late model motherboard and CPU especially since the board was probably manufactured before the CPU and while Asus was still working on the new BIOS.
I've actually seen this type of craziness with Gigabyte's GA-X58A-UD5/UD7 motherboards when they first came out.... The initial BIOS didn't support Intel's 980X CPU's and you couldn't update the BIOS unless you had a 920 lying around.
In short if you bought this motherboard and a 980X chip, you couldn't use it unless the BIOS was updated. Since you can't update a BIOS without a CPU, and the 980X was useless until the update, you needed a 920 CPU to update the BIOS. So your choices were to send the board back for the update, pay a servicing tech for the update, hope you got a board with a newer update, or find/buy? a 920 CPU
Anyway I’m glad to hear you got your issue sorted out.
Enjoy
This motherboard required a out of the box update new if you wanted the 1333 bus.
...that shows how old this thing is getting.
fortunately you could boot with the 1333 chip and memory it just underclocked it until you applied the bios update.
The opposite could work here as well in that the board was released about the same time the new chips were released - My example of the Gigabyte's X58A UD5/UD7 and the release of the i7-980X CPU for instance.
I'm not saying your point is wrong, especially since I know nothing of AMD chips or motherboards, I'm just pointing out that the opposite could work as well.
Well amd's don't even work on a bus system the way you would understand it from using intel.
I have a old AMD fx60 rig playing media server in the other room.
That was a nightmare of a setup, paid nearly 1100 bucks for that chip new and had all kinds of pain getting it working on the first mobo I put i on. (dfi lanparty pro expert)
I suppose you should be glad you don't have this Asus motherboard:
Newegg.com - ASUS P8P67 (REV 3.0) LGA 1155 Intel P67 SATA 6Gb/s USB 3.0 ATX Intel Motherboard with UEFI BIOS
I don't know what's happened to Asus in recent Times. I have an old Asus P3 motherboard which has worked faithfully for 10 years.
