Z77 EXtreme9 won't shutdown or restart or sleep

[king107s]

I have had my ASRock Z77 Extreme9 for about a month and love the board but... I noticed that resume from sleep which had been working flawlessly started to hang a few times. Now when I tell the computer to shutdown windows will indicate that its shutting down, the window will go black but the computer stays on and the mainboard indicates error code 05 which in the manual is 0x05 OEM initialization after microcode loading. I then have to hold the power button to get it to shut off. The same thing happens when I tell it to restart. If I tell it to sleep the same thing happens except I get mainboard error code 03 which in the manual is 0x03 North Bridge initialization after microcode loading.

I started off with the latest BIOS revision and all the most current drivers for this build. The system worked flawlessly for a month before this started happening all on its own.
My Hardware:
CPU Intel Core i7-2600K
MB ASRock Z77 Extreme9
RAM G.SKILL Ripjaws X Series 8GB (2 x 4GB) DDR3 2133 9-11-10-28
VC Sapphire Dual-X OC 7970 3GB
SSD 120GB OCZ Vertex 3 SATAIII
HDD RAID0 2x1TB Seagate Barracuda 7200.12
PSU Corsair AX1200

I've recently seen some other posts regarding this issue but no solutions... I'm hesitant to reset the CMOS just to see if it will help because I'll have to backup and rebuild the RAID array.

I hope someone can help!

A hard reset of the CMOS fixed the problem, for now...

Re: Z77 EXtreme9 won't shutdown or restart or sleep

i have this same problem, except i have the Z77 extreme4 with an i5 3570k. but i don't get error codes.

i noticed that sometimes when the system restarts properly, it doesn't actually restart. it goes into some stupid deep sleep and snaps right back out of it. when windows comes back on i sometimes see the programs i had open when i hit the restart button.

maybe the two things are connected?
