Occasional Blue Screens

Archived from groups: alt.sys.pc-clone.dell (More info?)

Dimension 8400, WinXP Home, P4 3.4, 6800 GTO video, SB Audigy, 5 months old.

For the past week I have been getting occasional stop errors referring to
ntfs.sys. I get the error and then a dump of memory, then a reboot.

I ran the complete Dell Diagnostics and the only non-passing item I came up
with was:

Error Code 3700:011B Msg: Expected fan on high RPM of 2100. Detected fan
RPM = 1195.

I didn't record which fan was in error but have rerun the all fan
diagnostics multiple times and haven't been able to duplicate the failing
fan error code. They all pass for now.

So, my question is, can anyone tell which fan this error code pertains to
and how should I approach the situation with Tech Support?

Thanks for any help you can give!
