Hi:
The folks on this thread are saying that is caused by a video driver issue-or a possible memory issue.

Run the memory diagnostics check in your BIOS and see what it reports.
Even if it reports OK, if you have two memory modules, remove one and run your PC on one module.
Unplug the PC from the A/C adapter and remove the battery before working inside the PC.
If the blue screens go away, you have isolated the issue to the first chip you removed.
Replace the bad memory module with one of the same specs.
If the PC continues to blue screen, remove that module and replace it with the other and test that one for a while.
If it doesn't blue screen, then replace the last module you removed.
Since your notebook has AMD hardware, you can try the AMD video driver directly from AMD and see if that makes the blue screens go away.
Run the driver verification tool and if AMD has a driver for you, it will direct you to the download after the tool runs.
