minidump?!? restart in the middle of doing things

[Lou]

Hello,
I have looked on the website for a solution but had no
luck. In the middle of me doing things, my computer just
restarts and i recieve this error.

BCCode : e3 BCP1 : 863CC6A8 BCP2 : 8645ADA8
BCP3 : 00000000
BCP4 : 00000002 OSVer : 5_1_2600 SP : 1_0
Product : 768_1

The numbers seem to be changing each time, but i assume
it is the same problem regardless.
Files Included:

C:\WINDOWS\Minidump\Mini091503-01.dmp
C:\DOCUME~1\Owner\LOCALS~1\Temp\WER3.tmp.dir00\sysdata.xml

AMD 2000+ 1.67GhZ
1GB RAM PC 2100
Please HELP ME!!!
Thank you

You have something that is crashing - and the system's 'automatically
restart' is cutting in. Turn this off: in Control Panel - System -
Advanced, click Settings in the Startup and Recovery section. There
uncheck 'automatically restart'. You can also usefully change the
'write debugging information' to (none) unless you are actively needing
a dump for debugging something, or to 'minidump' if you are getting
errors that you wish to report on to Microsoft. You may now get a Blue
screen failure instead, but at least will get better guidance as to what
is happening

The important item there is the initial Error code, E3 - see

and click on E3 in the left column to see if there are any useful
