Asus Laptop Unexpectedly Shuts Down While Sleeping

I have an Asus laptop, i7-3610QM 4-core, 6 GB of RAM, 750 GB hard drive space. When I close the lid to put it to sleep, it shuts off, and gives me the Windows Error Recovery screen upon restart, saying is was shut down unexpectedly.

The power options are all set to sleep when the lid is closed, both on battery and when unplugged. I went through the forums and tried a few suggested solutions (chkdsk, /scannow, updating drivers, etc), and so far nothing has provided a permanent fix.

I have a Wacom tablet, and I saw that other users were having problems with an associated pen/tablet driver causing the shut down, but I downloaded and installed the most recent one on their site, and still no results.

I'll upload the zip file obtained from running the sevenforums tool as well. If you guys could offer any more suggestions, it'd be greatly appreciated.

Thanks. I do have Power4Gear installed. Looked through it, but I didn't really know what to look for, though there is a "Turn Off Hard Disk" option with a time. Though, I've always had this installed (came with the laptop), and this unexpected shutdown problem only started last week. I've had the laptop for about 6 to 8 months right now.

Can I disable this software, or will it hinder performance?

Unlocker was the latest program I installed, but I had that on a previous Toshiba laptop and it never caused problems. My last 10 updates other than that were:

Google Talk Plugin
Starcraft II update
4 Nividia updates
Java 7 update
2 WebTablet plugins for Wacom tablet
Wacom Tablet driver


I did just notice that my computer's been set to Power4Gear High Performance instead of regular High Performance, so I'll switch that and see what happens. I have yet to try a system restore, but I probably will if nothing else works.

Cool, thanks for the help. I'll try your advice for a day or two and reply back if anything else happens. If Power4Gear turns itself on I'll just uninstall it. Thanks again.

Okay, well I uninstalled Power4Gear, and before putting the system to sleep, I manually end the two Wacom tablet processes that I can using the task manager, and it's still shutting off during sleep, with the same error message.

What still perplexes me is that I can leave the laptop plugged in overnight, and 7 hours later it's still in sleep mode, running fine. I can leave it unplugged for an hour, come back, and it's shut down unexpectedly again. Sometimes it goes for 4 hours unplugged before shutting down, sometimes it goes 20 minutes. The sheer randomness of this problem is one of the most confusing things I've encountered in all of the years I've owned a computer.

I unfortunately don't have a restore point available that's further back than a few days ago, so System Restore is out of the question. My only real idea (other than formatting the hard drive) is installing Windows 7 Professional over my current Home Premium. I'm not sure if this would even possibly solve it, but I'm reaching my wit's end.

I also started using the error logging function from the boot menu, and found my system is having consistent trouble loading these drivers:

\SystemRoot\System32\DRIVERS\srv.sys
\SystemRoot\System32\Drivers\NDProxy.SYS
\SystemRoot\System32\drivers\dxgkrnl.sys
\SystemRoot\System32\drivers\vga.sys

Still looking for a foolproof fix for this, or even a cause, as I read on other forums it could be anything from a driver issue to a hardware problem. Any more suggestions?
