I just installed 2 1GB PC5300 memory
modules to replace the 2 512MB PC4200 memory modules that shipped
with my laptop. Same brand: Hynix.
All memory diagnostics (CMOS,
Diagnostic Partition and Dell Support Center) report no problems with
System Memory. Nonetheless, I swapped the position of the 2 PC5300
modules and ran all the diagnostics again. No problems again.
After I installed the bigger memory
modules, I looked at my Device Management Console and saw that I now
have a yellow exclamation mark next to the Network Adapter labeled

that the 2 files are identical. When I click the “Roll Back Driver”
button in the Driver tab of the Properties dialog box, I get the
message “No driver files have been backed up for this device.”
I have booted with boot logging enabled, but have no idea where the boot log is or what program I use to read it.
I uninstalled RASPPPOE by carefully
following the directions that came with the program, including
deleting the oemx.inf and oemx.pnf files that RASPPPOE produces in the C:\Windows\inf folder. I
then installed RASPPPOE again. I still have the yellow exclamation
Considering that my laptop is working
fine and that I have no problems with my ADSL connection, I'm willing
to live with the yellow exclamation mark. There is a possibility that
upgrading my memory is not related to my WAN Miniport (PPPOE)
problem. After all, the unofficial Microsoft motto is “Windows is
