Z77A-GD65 Will not Boot
« on: 05-February-20, 02:23:53 »

This morning my Z77A-GD65 (MS-7751  VER: 2.1) will not boot anymore.

Have made a video of the codes on the motherboard, and tried to write them down. They are as follows. Some could be incorrect because it is sometimes hard to see the correct code.

10 19 15 38 56 46 55 36 4F
88 19 15 38 56 46 49 55 36 4F
10 19 15 38 56 46 55 96 98 4F
03 19 15 38 56 46 99 55 36 4F
88 19 15 98 56 46 55 36 4F

When I just look at the codes, instead of examining the video, I see:   19 15 30 56 46 55 4F  being repeated

These kind of codes keep on displaying and nothing happens.

Have tried a BIOS clear, but without any result.

Any help would be appreciated.

Do you have tried to update BIOS before this happens? [say running Live Update]
or its happens out of no where?

Did you remove power cord from the PSU 1st? (else it has no effect)
see >>Clear CMOS Guide<<

Have you also tried to boot with 1 memory stick only in DIMM-2 slot?

Have not made any changes to my system in the last year.

Yes I did, by following that instruction

Have you also tried to boot with 1 memory stick only in DIMM-2 slot?
Just did, put 1 memory stick in DIMM-2 slot, cleared BIOS again, but still the same result and codes.

In addition to the above did some extra tests with the memory modules, on my PC with only the PSU and CPU installed, and a monitor on the VGA port.

In total I have 4 memory modules of 4GB each.  

Did all kind of combinations of one piece of memory in different slots, and also all kind of combinations of 2 pieces of memory in slot 2+4.

But in all cases I always get the codes 03 19 15 56 55 36 4F, which sequence is repeated, and nothing else happens on my PC or Monitor.

It would be strange if all my 4 pieces of 4GB memory have all suddenly become defective.

Could it be that there is a wrong memory setting in the BIOS?  If so, how can I review or change it, since the startup never comes to the stage that I can enter the BIOS settings.
The memory is:
Corsair Vengeance Low Profile Blue CML16GX3M4A1600C9B
4x 4GB
DDR3
1.600 Mhz
CL9 (9-9-9-24)
1.5V

Why do you even think it's the memory?
I suppose one module can fail after some time of use even it is not a common thing but certainly not all 4.
For such old system I's suspect either the motherboard or the psu.
The debug code is completely useless so there no help there, but you can try and ask msi what is it. >>How to contact MSI<<

After my last tests with all kind of combinations of memory modules and slots, I also think that a bad memory module is not the cause of the issue.

About the PSU, it is a Corsair AX760 Platinum PSU, which has recently been replaced in 2018.

Before I contact MSI Support, would like to understand the following:

1). Could it be that there is a wrong memory setting in the BIOS?  If so, how can I review or change it, since the startup never comes to the stage that I can enter the BIOS settings.
The memory is:
Corsair Vengeance Low Profile Blue CML16GX3M4A1600C9B
4x 4GB
DDR3
1.600 Mhz
CL9 (9-9-9-24)
1.5V

2). The codes which are constantly repeated are 03 19 15 56 55 36 4F
03 19 15 are normal codes
56 = Invalid CPU type or Speed
55 = Memory not installed
36 = CPU post-memory initialization. System Management Mode (SMM) initialization
4F = DXE IPL is started
Can the above codes, perhaps indicate what is wrong with my PC?  
Also, the first error code that appears (56) surprises me, since it is about Invalid CPU type or Speed.

If there are any wrong settings they are due to a failure of cmos maybe.
Why would settings be suddenly wrong after they been ok for 7 years?
Default setting (after clearing cmos) should be just fine.

Where did you get the codes from?
From the manual
Quote
11~14,32~36,56~5A Early CPU Initialization
1D~2F,31,3F~4E,50~55 Early Memory Initialization
No 4f code.
