Dell Studio 1558 - BSOD once per day

The dmp(s) point to ntkrpamp.exe or ntoskrnl.exe as the probable cause. We know this is not the case, as these are core OS files, and will definitely not cause a BSOD. They are just the default files the debuggers blame when they can't see a better cause. Enable driver verifier using the following procedure..

- Go to Start and type in "verifier" (without the quotes) and press Enter
- Select "Create custom settings (for code developers)" and click "Next"
- Select "Select individual settings from a full list" and click "Next"
- Select everything EXCEPT FOR "Low Resource Simulation" and click "Next"
- Select "Select driver names from a list" and click "Next"
Then select all drivers NOT provided by Microsoft and click "Next"
- Select "Finish" on the next page.

Reboot the system and wait for it to crash to the Blue Screen. Continue to use your system normally, and if you know what causes the crash, do that repeatedly. The objective here is to get the system to crash because Driver Verifier is stressing the drivers out. If it doesn't crash for you, then let it run for at least 36 hours of continuous operation (an estimate on my part).

If you haven't done so already, you can turn off driver verifier, which will allow you to boot into 7 normally, by opening driver verifier the same way you did before, select "delete existing settings" and click finish.
