If the MCE decoded as "internal timer error", the next most likely thing is a faulty CPU or mainboard.

Ok I'll get unit replaced today and see where it goes...

[manjotsc]

I went back to the vendor and got the same unit replaced, but it still be crashing after few minutes.

@manjotsc

Then maybe it's a memory (RAM) problem.
Because the error is the same

MCA: Bank 3, Status 0xfe00000000800400 (0000 0100 0000 0000)
MCA: Global Cap 0x0000000000000c09, Status 0x0000000000000004

[manjotsc]

Ok I'll try replacing the ram and see...

@manjotsc
Perhaps the problem is not in memory
This error has long been known , but whether it is solved - I do not know

This guy also had the same issue, he recommend the replacing the NIC...

@manjotsc
Maybe I can't say anything. I don't know the configuration of your hardware other than the processor + 4 lan adapters Intel (igb) + 1 lan adater Intel(em). One thing is clear, this is a problem with the equipment.

100% a hardware issue though the exact nature isn't always obvious as to which piece of hardware is at fault.

Clear as mud.

[manjotsc]

We can't do nothing about to find out the exact issue?
I am using the Dell Optiplex 790

[jimp]

Your hardware vendor may be able to make better sense of those MCA errors. I'd start there.

[manjotsc]

@jimp You mean contacting dell?

[jimp]

If that is who made the system, then yes.

[stephenw10]

Do you have a NIC expansion card in it? Try removing it you have nothing to lose.

At least one of those errors looks almost identical.

I had tired, finally I just swapped the dell motherboard with American Megatrends board. Everything seems to working fine as of 3h 15 minutes of up time...

[manjotsc]

Thanks everyone above, for helping.
