Uninstall Avast! antivirus, it's known to contribute in BSODs. Replace with MSE at least to test. Also uninstall any third party firewall and back up tools if you have them.

Recommended antivirus program for Windows 7 based on stability compared to others:-

• Microsoft Security Essentials - Free Antivirus for Windows
• Malwarebytes - The Free version
• Good and Free system security combination.

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

Code:

Driver	c:\windows\system32\drivers\atikmdag.sys (8.1.1.921, 5.76 MB (6,037,504 bytes), 8/18/2009 3:48 AM)

Update to the latest drivers for your graphics card but first uninstall them from the control panel. Click on the Start ► Control Panel ► Programs ► Uninstall a program ► Uninstall everything related to ATI. Delete remnants of driver using Driver Sweeper. Download the latest version from the AMD website OR from device manager OR from reliable source like Filehippo.com.

Look for an update on your BIOS version:

Code:

BIOS Version/Date	Hewlett-Packard F.25, 7/10/2009

Free up your start-up, keep nothing except the antivirus.

• Startup Programs - Change

Run the System File Checker that scans the of all protected Windows 7 system files and replaces incorrect corrupted, changed/modified, or damaged versions with the correct versions if possible:

• SFC /SCANNOW Command - System File Checker

Run Disk Check on your hard disk for file system errors and bad sectors on it:

• Disk Check

See if the stability of your system returns.

If not, go ahead with Memtest86+

Take memtest. Run for 8 passes and test each stick in a know good slot for an additional 6 passes.

• RAM - Test with Memtest86+
• Guide to using Memtest86+ - Geeks to Go Forums

The goal is to test all the RAM sticks and all the motherboard slots.

Check your motherboard manual to ensure the RAM sticks are in the recommended motherboard slots. Some motherboards have very specific slots required for the number of RAM sticks installed.

If you get errors, stop the test and continue with the next step.

1. Remove all but one stick of RAM from your computer (this will be RAM stick #1), and run Memtest86 again, for 7 passes.
Be sure to note the RAM stick, use a piece of tape with a number, and note the motherboard slot.
If this stick passes the test then go to step #3.

2. If RAM stick #1 has errors, repeat the test with RAM stick #2 in the same motherboard slot.
If RAM stick #2 passes, this indicates that RAM stick #1 may be bad. If you want to be absolutely sure, re-test RAM stick #1 in another known good slot.
If RAM stick #2 has errors, this indicates another possible bad RAM stick, a possible motherboard slot failure or inadequate settings.
3. Test the next stick of RAM (stick #2) in the next motherboard slot.
If this RAM stick has errors repeat step #2 using a known good stick if possible, or another stick.
If this RAM stick has no errors and both sticks failed in slot#1, test RAM stick #1 in this slot.
4. If you find a stick that passes the test, test it in all the other motherboard slots.

If Part 2 testing shows errors, and all tests in Part 3 show errors, you will need to test the RAM sticks in another computer and/or test other RAM in your computer to identify the problem.

In this way, you can identify whether it is a bad stick of RAM, a bad motherboard, or incompatibility between the sticks.
