BSOD Playing League of Legends, Using Skype, MS Security Essentials

Dont think that is the issue
But with the clean boot, do not be in a rush. You can use the computer just fine in clean boot, in fact you get super fast boots. Once we are certain no BSODs in clean boot, we got it licked.

This is the second case today, with this game. It may just be too intensive for your computer.

Okay, good to know about the clean boot!

And the game is definitely not too intensive for the computer-- it's a newer model designed for gaming and has a lot more powerful CPU, GPU, and more RAM than this game needs. And just to clarify, the fact that it said "driver power state failure" doesn't help at all?

edit: I don't understand your comment, "This is the second case today, with this game. It may just be too intensive for your computer." My computer hasn't crashed in the last 2 days.

Another member has the same problem with the same game. hmm.

Give us the new reports

Driver Verifier
I'd suggest that you first backup your data and then make sure you've got access to another computer so you can contact us if problems arise. Then make a System Restore point (so you can restore the system using the Vista/Windows 7 Startup Repair feature).

In Windows 7 you can make a Startup Repair disk by going to Start....All Programs...Maintenance...Create a System Repair Disc - with Windows Vista you'll have to use your installation disk or the "Repair your computer" option at the top of the Safe Mode menu .

Then, here's the procedure:
- Go to Start and type in "verifier" (without the quotes) and press Enter
- Select "Create custom settings (for code developers)" and click "Next"
- Select "Select individual settings from a full list" and click "Next"
- Select everything EXCEPT FOR "Low Resource Simulation" and click "Next"
- Select "Select driver names from a list" and click "Next"
Then select all drivers NOT provided by Microsoft and click "Next"
- Select "Finish" on the next page.

Reboot the system and wait for it to crash to the Blue Screen. Continue to use your system normally, and if you know what causes the crash, do that repeatedly. The objective here is to get the system to crash because Driver Verifier is stressing the drivers out. If it doesn't crash for you, then let it run for at least 36 hours of continuous operation (an estimate on my part).

If you can't get into Windows because it crashes too soon, try it in Safe Mode.
If you can't get into Safe Mode, try using System Restore from your installation DVD to set the system back to the previous restore point that you created.
Driver Verifier - Enable and Disable

The clean boot tells us its not any installed software. Lets try to find the cause with Verifier.

The only real clue, without the dumps is Bcode 7E and it means the cause is possibly:
Insufficient disk space, Device driver, Video card, BIOS, Breakpoint with no debugger attached, Hardware incompatibility, Faulty system service, Memory, 3rd party remote control,

Make sure that you have enough disk space
Go to the website of the manufactuer of your hard drive and test hard drive
Update your Video card driver
Have you made any changes to software or hardware about the time of the problem
Test memory
I did not check to see what has already been done.

Almost forgot

Run memtest for 8 passes
Then test each individual stick in a good slot for 6 passes.
If you have dual channel, the results may be incorrect, if shows pass.
