GA-H55M-S2 rev 1.3 recent problem with delayed boot

[Dark Mantis]

The memory probably isn't a problem then although it is good to double check as then we can at least discard that as the cause.

Well, it took all night, but I ran both sticks, 1 at a time.  11 passes on the first no errors, 12 passes on the second no errors.  The BIOS settings you recommended are my defaults.

[Dark Mantis]

Well that's good anyway so at least now we can say that the memory is ok and the controller.
The CMOS has been cleared and Optimised BIOS Defaults loaded.
The PSU has been swapped out with no change.

It would be worth checking for bent pins on the CPU socket also.

Very carefully remove the heatsink and fan. Probably a slight twisting motion is best to release the two as the thermal paste can act like a glue.

Once off remove the CPU taking extreme care both physically and electrically(static) and place somewhere safe.

Make sure that the lighting is very good and even.

Now scrutinise the socket for any pins that are out of alignment, even slightly.
If in any doubt whatsoever take a couple of macro (close up) photos of the socket and post them on here for us to check.

Also look at the bottom of the CPU at the lands (little copper circles) and make sure that there is a mark in each somewhere near the centre.
If there are any missing marks or any of the pins are obviously bent then that is your problem.

Before refitting the CPU clean off all residue of the old thermal paste and the same on the heatsink and then apply a small amount (about the size of a grain of rice) to the centre of the CPU once it is inserted in the socket.

The system ran fine for the first 5 months, and I haven't had the cpu out since I built it.  I will remove the cpu to check for bent pins and while I am at, I will swap processors to verify that the processor isn't the problem

[Dark Mantis]

I understood that the system had been running ok but sometimes heat can cause pins to bend or even burn in extreme circumstances so it is still worth checking. It is also another thing to cross off the list along with the processor if you can swap it out.

I have been fighting with exactly the same issue for a few weeks - tried almost everything, have no idea what's wrong, especially when entering suspend (S3) mode and waking up ...

Usually it takes about 2 sec but these days about 15-20sec, input signal disappears immediately but PC is still running - if I hit reset button there is more fun - nothing happens !! it is still running and in a few seconds it just turns off completely, after another few seconds it starts again by itself

what the hell is going on there ? I have checked everything - even bought new power supply ( seasonic !) - nothing changed, flashed new bios using @bios - nothing, yesterday I have the same info about fix me (firmware corrupted)

I think there is something terribly wrong with communication between bios chips with code and controller that reads the data from it

I think there might be whole series of faulty MB since these are exactly the same issues in many places

motherboard is 2,5 years old - this is pathetic, I have never had issue with it

there is also another issue under win7 x64 ultimate about "driver stopped responding and has recovered" - it started with another issues with motherboard

never ever again any gigabyte product for me, need to check warranty period

Hello!

I think, I resolve the problem.

First I checked too memory, PSU, HDD, VGA components, upgrade the BIOS, etc., but problem not resolved.

How I to resolve problem?

When PC has switched off, I remove power cable from PSU, then I remove CMOS battery, then many times pressed power button, after approximaly 30 - 60 sec. I put back CMOS battery, connect power cable with PSU and switch PC on. When PC starting first starts BIOS, after appeared table (between BIOS startup and OS starting). Then was 5 profile:

Profile 1 - Default;
Profile 2 - Last good ... (I don't remember)
Profile 3 - 2 times
Profile 4 - 3-5 times (I think)
Profile 5 - 7 times (I don't remember too)

I think, I have profile 2 active, but I choose profile 1 - default, and pc to start working normally. Now PC starting normally, now PC switched off himself  (normally), now start working reset button, before not working. Now I haven't this problem, if you have this problem to try my recipe!  

P.S. Sorry my knowledge of English not perfect, but I think here can all understand!
