My sister turned on the computer this morning and the logonui.exe error
message came up. We restarted the computer numerous times over half a hour,
and it did not go away. This message said that the memory "cannot be read".
I'm sending this from safe mode, where I checked on a previous solution
someone offered about regedit.exe - windowsnt/software/windowslogon (I'm
sorry, I cannot remember the exact path). I checked it and the data value is
logonui.exe. We've been having the problem on and off for a couple of days,
but not to the extent where we have to access files from safe mode. I would
really like to go back to normal. Any help will be appreciated. I have all
the XP CDs, AVG is up to date.
Thanks

Make sure the machine is clean from malware and viruses.

try this fix and reboot your machine.

Run this command if the above didn't help:
sfc /scannow click [OK]

It fixed itself last time, I'm not sure how. I turned it on again at 06:45
to run a scan (I find it easier to run early in the morning). The message
came up. I went into Safe Mode for a minute, thinking it would help. I
restarted the computer from Safe Mode and the message kept coming back. I
have tried twice to go in Safe Mode and it hangs at the point where the list
ends and just before the Safe Mode screen comes on - ie it says
multidisk..... and then hangs. I restarted the computer and CHKDSK is
currently checking for consistency. I'm letting that run in case, I don't
know if it'll help. The only new software I added was the upgrade to
RealPlayer yesterday. It required a reboot, which I did. The first time -
the message appeared. The second time - it went back to normal. I'm fearing
that I might not even be able to access Safe Mode. As soon as CHKDSK has
finished, I'll update this thread. What I do not understand is

what is logonui.exe
what it means
why it keeps coming
how to fix it

CHKDSK finished. It found a ton of errors, which it repaired and now it is
back to normal.

I ran Stinger and it came with no errors. I then restarted the
computer and the message appeared again. I'm still using Safe Mode to
send these messages. I have coursework to do and I cannot do it in
Safe Mode. I tried your link and it did not come up with any
problems. I cannot run sfc in Safe Mode - it will not let me. A
screen flashes and then nothing else.

Logonui.exe is: Windows Logon User Interface, located here:

Look in the right Pane/window for error message with red (X) or Yellow

causer.

I've decided that I'm going to reinstall XP. It has happened for three days
straight and might go away. If you want, I can send you the information
requested from Safe Mode. My screen is no longer blue, it just remains black.
