Hi guys, thought I'd try asking my question here... I tried in the Asus forums with no replies.
My Asus Z87 is having boot issues. The PC boots properly at times but after 1-3 days of running, it just "shuts off" and restarts to qcode 71 with the VGA_LED on solid. If I power on and try enough times, eventually it will post again and be fine for 1-3 days.
I've tried removing the video card, booting with only essential components, etc but the issue is still happening.
Do you have the latest BIOS? and the latest mobo drivers? Might also want to run Memtest on each stick, (maybe 4-5 passes), that would be for starters, if not a BIOS or driver issue then maybe a stick of DRAM going bad or possibly PSU
