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.

MCA: Bank 3, Status 0xfe00000000800400
MCA: Global Cap 0x0000000000000c09, Status 0x0000000000000004
MCA: Vendor "GenuineIntel", ID 0x206a7, APIC ID 2
MCA: CPU 1 UNCOR PCC OVER internal timer error
MCA: Address 0x3fff80c812df
MCA: Misc 0x3ffff

$ mcelog --no-dmi --ascii --file mce.log
Hardware event. This is not a software error.
CPU 1 BANK 3 
MISC 3ffff ADDR 3fff80c812df 
MCG status:MCIP

Clear as mud.

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

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.

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...
