Motherboard issue.

[Ghost]

I have an old gen mobo - Asus P6T-se and Core i7 920. I have not used these mobo and cpu for while since i had issues with the motherboard.

Most of the time when i connect 24pin power cable, it does not power on. But rarely it works. (CPU fan spins, beep sound) On board power switch is ON, since motherboard is getting power from PSU. PSU works fine with my new PC.

I tried everything i can do (CPU re-seated, checked CPU fan)


That i7 920 is powerful than my current CPU. This is the reason that i want that motherboard to work.

Take the time to look at the pins on the ATX 24pin and CPU 4pin (or 8pin) connectors; both on the PSU and Motherboard side and ensure they aren't spread out or bent.

When Motherboard has power related boot issues, try the motherboard outside of the case. Put in on a safe surface, like the motherboard box.

I tried out side of the case. ATX 24pins and 8pins connectors are't bent. PSU bought with new PC, it works fine.

without the 4/8 pin eps power to the cpu, the board will turn on, but it will not post or boot

Then try reset the CMOS and see if it powers on properly after that.
Otherwise it might just be dead and time to replace. You can replace under warranty from the maker, but I doubt the warranty is still any good depending on what the coverage was, as most are around 3 years; unless otherwise stated from the maker, as some models might have shorter/longer warranty as well.

I tried resetting CMOS as well. But the thing is sometimes it will turn on and post the beep sound. No warranty for this 5years old X58 motherboard :(

Then replace it or ditch the motherboard, sell the CPU and upgrade it.

5 yrs is plenty....retire it. Time to pony up and treat yourself to a badass modern PC.

i already bought a pc year ago, but this i7 920 is more powerful than my current A10-7700K

Too right, keep that i7 920 running, there's little point upgrading. Get it working, clock it up to 3.6GHz - 4GHz and keeping for another couple of years until 8-Core is mainstream.

I'm currently running a P6T Deluxe and have stacks of experience with your motherboard (one of my favourite from it's generation). One trick that could get a system working was organising the RAM properly. Try running with a single RAM stick in the furthest orange slot if this boots consistently add the next stick to the middle orange slot. Also on an older board you may need to replace the CMOS battery to get settings to stick.

Yea boards that old, replaceing the CMOS battery is probably needed.

you plugged in the 24 pin normaly theres another near the cpu fan 4pin? or 4-8 pin? from the coment above,possibly youve missed it and it isnt plugged in?

Thank you all for your suggestions. I tried everything above stated. I tried even without the RAM to check whether it gives error code. It does not even fire up when i press the power button (i used both on board power button with red led and case button)

i used different power supplies to check. (Raidmax 500AF and Seasonic G550) but no help.

I live close to the beach, since this can be reason a for a dead motherboard right? I have seen some parts of the motherboard have being corroded. Board is working sometimes this is the reason i have raised up this issue here. I have never heard dead motherboards working sometimes.

That it works sometimes is good news, mine was similar, the previous owner thought it was faulty but it was just a question of settings and a BIOS update, it's been running a 920 at 3.6GHz for a few years since then and I recently upgraded it to a 980X.

Corrosion is a bad sign, but I have had liquid cooling leak all over a running P6X58D and had it survive, I let it dry out (with help from a dozen or so systems running Prime and Furmark) overnight and it POSTed fine the next day.

i had a problem with one of my system keep shooting down it was a bad Power-Supply, i have exra Power-Supply to test that fix the problem.

How to Check a Power Supply

Two Parts:Testing if it Powers OnTesting the Output

The power supply is often forgotten when it comes to diagnosing computer problems, but testing your power supply first can save you a lot of troubleshooting headaches down the road. If your computer experiences Blue Screen of Death crashes, hard drive errors, or just plain won’t boot, you may be dealing with a faulty power supply. Run these quick tests before you start swapping out expensive hardware.
