Strange problem with resuming from S3 sleep suddenly.

Built a new rig a few weeks ago.

Gigabyte GA-Z68A-D3-B3
Intel Core i5 2500K @ 4.5GHz
8GB G. Skill Ripjaws X DDR3 2133

The CPU has been tested stable at this speed for 38 hours in Prime95. Six hours in Linpack. C1E and EIST are enabled.

Until a few days ago, S3 Sleep generally worked fine. Suddenly, I've run into a strange problem that's causing sleep to be essentially non-functional.

When I attempt to wake my PC from sleep, the fans and hard drive begin to spin up. After spinning for less than a second, they shut off. The computer sits idle for a few seconds, then begins a cold boot.

I have no idea what could be wrong.

DId you install SP1 recently? There have been problems reported with SP1 and sleep on certain systems.

Are you overclocking? This can cause problems during boot, which is exactly like the symptoms you describe.
