System hangs when going to sleep mode / idle

[MisioSoup]

Hey Gang!

Just built my PC and everything is going really well. Except, whenever I leave the computer alone for too long or actually manually put it into "Sleep" mode, it won't wake back up.

When I do a hard reset, I get a message saying "Overclock Failed!" and asks me to press F1 to go into the BIOS.

But I'm not overclocking. At least, not knowingly.

I read on some forums to set C3 and C6 in my BIOS to "Disabled". Which I have tried, but that hasn't solved the problem.

Here's my build:

Intel Core i5 2500K Quad Core Unlocked Processor
ASUS P8P67 Intel P67 Motherboard
CORSAIR HX Series CMPSU-750HX 750W
G.SKILL Ripjaws X Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1333
Western Digital Caviar Black WD5002AALX 500GB 7200 RPM 32MB Cache
Lite-On IHAS124-04 Internal DVD Writer
TP-LINK TL-WN722N USB 2.0 High Gain Wireless Adapter
Asus EAH6870 Graphics Card

Anyone else experience a similar issue and found a solution?

Until you can exchange that motherboard for the repaired model, I'd turn off power management and not let it go to sleep. The vendors should have the fixed boards sometime in April.
