Sometimes drivers remain, not completely uninstalled. Follow this tutorial for complete removal of drivers of the particular program:

Security software?

We recommended Microsoft Security Essentials from a strict BSOD perspective. Is most compatible & provides most stability compared to other antivirus app/Internet Security Software.

• Microsoft Security Essentials, Free antivirus for windows
• Malwarebytes Anti-Malware Free
• Good and Free system security combination

   Warning

Do not start the free trial of Malware Bytes; remember to deselect that option when prompted.

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

Perform a System File Check to check the integrity of all protected Windows 7 :

1. Click on the start
2. Type CMD on Search
3. Left click and Run as Administrator
4. Type
   Code:

   SFC /scannow

Full tutorial here:

• SFC /Scannow Command - System File Checker

Check your hard drive(s) for errors by running chkdsk

• Check your hard disk for errors
• Disk Check

Install all updates including Service Pack 1:

• Learn how to install Windows 7 Service Pack 1 (SP1)

Let us know the results.

You can find there anything saying AMD-Display? If you see the screenshot in How to Clean Left Over Driver Files with Driver Sweeper, It is there on the top. Check/tick it and proceed.

Keep us posted :)

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

• How to Test and Diagnose RAM Issues with Memtest86+

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.

   Information

Errors are sometimes found after 8 passes.

   Tip

Do this test overnight, before going to bed.

Good to hear

Let us know if you have further BSODs.
