Op has latest/only bios released 2011 according to Dell web site, odd its same bios number that shows as updated 2 years after the one in system.
No drivers that spring out at me there. The 3 from 2007 make me twinge a little but its normally only overclocking drivers that cause WHEA errors, but they can be caused by any hardware.
Date Driver Description
Jun 14 2007 SiWinAcc.sys SATALink Accelerator driver
Jun 20 2007 SiRemFil.sys Filter driver for Silicon Image SATALink controllers
Oct 03 2007 SI3132.sys SiI 3132 Serial ATA Miniport driver (Silicon Image, Inc)
Did you ever have Kaspersky installled? Trying to figure out what SATALink Accelerator driver is for, its from 2007.
do you have an external CD/DVD drive attached? the 2nd file seems to be CD/DVD-ROM Device Lower Class Filter
I wonder if the errors are caused by the DVD drive you playing Flight Simulator through? Drivers sure are old.
Otherwise
check if PC is overheating, perhaps run
HWINFO and log the temperatures and other sensor records in system. Might give a clue,
When it starts, tick in the little box sensors only and click run. When program loads, there should be 4 icons down bottom, one looks like a clock. Press the button to the right of it called Logging start, it will open file explorer and let you name/create a log file
