I keep getting blue screens after using my notebook 2-4
times.  I ran the diagnostics test with the help of Dell
support.  There were no hardware problems but it is still
occuring. The technical information given is as follows:

for a few seconds, then when starting the notebook again
Windows booted and showed the following error report:
