A friend of mine is getting a blue screen with a description of
PFN_LIST_CORRUPT and a stop code of 4e. Research shows that it could be a
bad driver or bad memory. Memory for his laptop is cheap, but I'd like to
do whatever I can to determine if it is a bad driver or bad memory or
anything else that could be causing the stop. Any help that anyone could
give me to resolve this problem for him would be greatly appreciated. Thank
you very much.
--------------------------------------------------------
First try running Memtest86+,
this runs from a boot floppy or CD you need to create.
and should eliminate or confirm if your ram is good
when running at the speed you now are. I don't
expect any problems as the memory you purchased
should easily run at your PC current speed.
Let it run for as long as you can, 2 to 4 hours,
if no errors by then your ram passes what I call a
"Basic Test".
See:
http://www.memtest.org/
Next is the torture test, it test both your CPU
and memory, again let it run for about 3 hours
and if it is still running (not in a Stopped state)
and has not reported any errors your good to go!
I would start "SpeedFan" before you run this test and
monitor your CPU temperature, you will know which of
the multiple temperatures readings displayed as soon
as you start the test as the CPU will start going up
in temperature.
Prime95 "Stress Test"
"FREE MERSENNE PRIME SEARCH SOFTWARE"
http://www.mersenne.org/freesoft/
Download and unzip. It's a standalone .exe file
when you first start this program you will see
a "Welcome to GIMPS" window. bottom right click
on the "Just Stress Testing" button. In the
"Run a Torture Test" window select the "Blend"
option. Leave the "Number of threads to run"
at 2.
Also for Core 2, Quad Core and i7 Intel there is
another CPU core temperature tool that is very good.
Core Temp:

For other issues try PassMark's "Burn In Test"
http://www.passmark.com/products/bit.htm
The trial version will run for 15 minutes, you can
pick what part of the computer you want to test such
as Video, CPU, Memory, Hard Drive or any combination
of the various test options.
