BSOD Driver Power State Failure

This is a HP pavilon dm4 Laptop, windows 7 64 bit.

The BSOD seems to always happen when the computer is plugged in, although it has happened a couple times when it wasn't. Its never when I am in the middle of doing something, only when I leave the computer alone for a while will it crash like this. For example, even if I am just listening to music or watch a movie, it doesn't crash. It's like it does this when it gets bored or something... As long as it is doing something it is fine.

I updated the drivers using HP's tool, but the problem hasn't gone away.

File correction

Sorry, I posted the incomplete file the first time... Here are the other files because the complete .zip file exceeded the maximum size.

Symantec/Norton is a frequent cause of BSOD's. Please remove it using its removal tool
:ar: Uninstallers (removal tools) for common antivirus software - ESET Knowledgebase

We recommended Microsoft Security Essentials from a strict BSOD perspective.
:ar:Microsoft Security Essentials, Free antivirus for windows
:ar:Malwarebytes Anti-Malware Free
:ar:Good and Free system security combination

Run a full scan with both (separately) once downloaded, installed and updated.

Use the System File Checker tool (SFC.exe) to determine which file is causing the issue, and then replace the file.

To do this, follow these steps:
1. Open an elevated command prompt. To do this, click Start, click All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator. If you are prompted for an administrator password or for a confirmation, type the password, or click Allow.
2. At the command prompt, type the following command, and then press ENTER: sfc /scannow
The sfc /scannow command scans all protected system files and replaces incorrect versions with correct Microsoft versions.

Number down items at start-up. Keep only your anti-virus, this also improves the time for logging into windows.
