Solved Random Reboots After Motherboard Replaced

[tiffosira]

Hey guys

My PC was running fine till one day motherboard's onboard lan stopped working !

I gave my motherboard for RMA and in return they gave me a repaired motherboard.

Since the change of motherboard the system randomly reboots itself.

Tried doing a clean install of OS, updated BIOS, updated drivers, checked temps but still it reboots.

Note: Tried windows xp for dew days and the system stayed fine without reboot.

Old Motherboard : Gigabyte Z68x-UD4-B3
New Motherboard : Gigabyte Z68xp-UD4
OS : Windows 8 Pro

Uploading the System logs too.

Please help !

Looks like there was a major BIOS update issued (for your replacement mobo) on 3/6/2013:

GIGABYTE - Motherboard - Socket 1155 - GA-Z68XP-UD4 (rev. 1.0)

GIGABYTE - Motherboard - Socket 1155 - GA-Z68XP-UD4 (rev. 1.3)

Looks like it applies to v1.0 and v1.3 of your new mobo. Please ignore if current.

Yeah already flashed with the latest uefi bios but still the issue exists.

Mine is rev 1.0

Could be that the repaired mobo was just tested (minimally) and shipped back out to you. If you can't localize the trouble with help from others on this board, I'd be RMAing that one as well. Good luck.
