error after startup

[jlc]

I sporadically get this error “The instruction at "0x7c91b1fa" referenced
memory at "0x00000010". The memory could not be "written" either at startup
or a minute or so after log into my profile. Anybody have a clue as to what
is causing this and a remedy to fix it.
When the error comes up I usually have to reboot because most programs and
computer are handicapped by it.
Thanks

It means one of your start up programs has gone walk about.

Some things to try:

1) boot into "safe" mode and see if the problems
recurs. If it does, it is probably a corrupted Windows
component. Try installing service pack 3. It may
overwrite the corrupted component

2) go into "msconfig" and go into "diagnostic startup".
If it works, go back into msconfig and select selective startup.
The idea is to divide and conquer until you isolate the
guy. If it does not work, see step 1 and step 3

3) worst case, do an "in place" reinstall of XP.

I'd install service pack 3 first
