I'm looking for a PC hardware expert who can help me diagnosing and repairing a PC motherboard.
Mombo is an Asus P6T deluxe ver.2 socket 1366.
Mombo fail in POST procedure.
Nothing ,dark screen.
I have check with another good power supply,another graphic card, pulled memory,nothing.
Power supply start,CPU cooler fan start,nothing else,no beep nothing!
Any help out there?
I have done some measurements around VRM and I didn't see any voltage across electrolytic caps.

My older PC has that motherboard. Make sure that the CPU cooler is not shorting out any PCB traces near the mounting holes. The stock cooler with plastic pins is fine, but aftermarket coolers with metal screws can cause shorts.

Often troubleshooting PCs requires swapping replaceable parts. Some of the power supply rails may be okay and other rails may be down. Sometimes that can happen because of bad capacitors on the motherboard. You may have to take your best guess and swap the power supply or the motherboard to find out if the problem is with one of those parts. Or maybe take it to a computer repair shop where they are equipped with spare parts to try.
Have you tried clearing the CMOS RTC RAM (pg 2-24 manual) ?
[edit] if the button cell battery died (12yr old motherboard) it might have effected the RAM contents

Not an expert and not familiar with that motherboard, but…
A lot the problems will develop because of the memory and the memory sockets, try use only one memory module and swap the sockets. You need a lot patience. If that doesn’t work you go to next step, graphic card etc..
But anyway, it is worth trying but taking it to a shop it is not! That computer is at least 13-14 years old old.

All suggestions are tried already.🙂
No beep,speaker connected, memory slot changed,one memory installed,power supply tested and changed.Clearing cmos tried.New battery installed.
Graphic card tested,new graphic card swapped.

Try re-seating the CPU. If that does not work, the motherboard or CPU has failed.
Socket 1366 machines are ~15 years old. They were very nice machines, though.

I know a guy who had an even older computer. The disk drive interface, file system, and OS architectures were long obsolete. But it had information on it that wasn't backed up and that the owner very much wanted to keep. He happily paid a shop to get it working so he could get his data into a newer computer.
On older machines, linux can sometimes mount the drive even if not native. Linux understands quite a few file systems. I think I've seen IDE->SATA interface thingies too.
Yes I know,it is an old motherboard,but I would be very happy if I can repair it.
It was very-very expensive mombo and a very expensive CPU.
Core i7 extreme edition. It was fully functional until it was stored due to the purchase of a new one.

There appear to be some used but working MBs out there: https://www.ebay.com/sch/i.html?_nk...9111X1517312Xd069c97b38a00756fb6501b2c0341a23
Depends if its worth it to the computer owner.

I would also connect the power LED (PLED with correct polarity) to the system panel connector. On page 2-40:
"6. After applying power, the system power LED on the system front panel case lights up. For systems with ATX power supplies, the system LED lights up
when you press the ATX power button. If your monitor complies with “green” standards or if it has a “power standby” feature, the monitor LED may light up or switch between orange and green after the system LED turns on."

He happily paid the shop to get the informations from a fully working hdd to another computer? Thats a different story than what the OP is dealing here. Your friend’s problem could’ve be fixed literally by anyone with basic PC hardware knowledge.
The OP situation is more complicated, possible hardware problem.
I built a lot of PCs, never though that a an expensive brand new graphic card will literally die after removing it from an working pc, or a motherboard will brick in the middle of the bios update, but these things happen.
It is somehow expected for a 15year old pc to develop problems, capacitors will start to die and trigger voltage regulators to die too.
It was a VERY old Mac. He doesn't live near here so I couldn't look at it. He didn't have anyone else to do it, so the shop fixed it.
