PLease update your wireless driver it seems to be what is causing the problem:

GetPointerFromAddress: unable to read from 831a9830
Probably caused by : memory_corruption

Followup: memory_corruption
---------

Code:

Causes: Memory, Paging file corruption, File system, Hard drive, Cabling, Virus infection, Improperly seated cards, BIOS, Bad motherboard, Missing Service Pack

We can eliminates atleast one of these because I can see you are not missing Service pack 1, so please do the following:

Run memtest86+ for at least 8 passes (do this over night it can take a long time):

RAM - Test with Memtest86+

Run these programs to check for virus infection:

Windows Defender Offline
Tdsskiller

Run the system file checker:

SFC.EXE /SCANNOW
Go to Start and type in "cmd.exe" (without the quotes)
At the top of the search box, right click on the cmd.exe and select "Run as adminstrator"
In the black window that opens, type "SFC.EXE /SCANNOW" (without the quotes) and press Enter.
Let the program run and post back what it says when it's done.

Then from the same command prompt run this command:

Code:

chkdsk /f /r

Check for a failing hard drive by following this tutorial:

Hard Drive Diagnostic Procedure

Have you run TDSSkiller?

Scan your system with the following:

• Kaspersky TDSSKiller How to remove malware belonging to the family Rootkit.Win32.TDSS (aka Tidserv, TDSServ, Alureon)

• ESET online scanner One-time virus scanner free with ESET online scanner

• Run Windows Defender as well. How to Use Windows Defender Offline

Heat:
- only use the laptop on a hard surface - with nothing blocking any of the vents.
- use a laptop cooling pad if possible
- blow out all vents with canned air (DO NOT use a vacuum cleaner or an air compressor, they can damage the components).
- ensure that the fan comes on and is blowing air out of the vent (may not happen at startup, but should happen after using it for a while).

For monitoring heat of the system, use Speccy or HWMonitor:

• Speccy System Information
• HWMonitor

• Post a screen shot using Crystal Disk Info: CrystalDiskInfo Standard Edition
• How to Upload and Post a Screenshot and File in Seven Forums

Make a hard drive test from the hard drive manufacturers website:

• Hard Drive Diagnostic Procedure

---

• 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:

• 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. Use the System File Checker tool to troubleshoot missing or corrupted system files on Windows Vista or on Windows 7
• 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. SFC /SCANNOW Command - System File Checker

I asked for some help on this part, I don't really know much about how you would go about doing that so I will see if some one else does.

I agree with X BlueRobot. The bad sectors are a warning of hard drive failure. My best advice is to recover your files and replace the hard drive. As BlueRobot says, you can copy the files using a live Linux CD, or Copy & Paste - in Windows Recovery Console. Either method will work as long as the drive is readable. I don't know of any way to pick and choose which sectors to install Windows. But, even if you could, your hard drive is fixing to fail, so it would do little good.
