Nod 32 Antivirus program & Windows Firewall are installed.
I am the owner and have Admin privileges on the PC, which incidentally, is Networked.
I do have a Guest account, but it is not used.
Here’s my problem:
On starting the PC, the motherboard manufacturer's splash screen comes up,
followed by the BIOS screen, Microsofts XP screen and then a Blank window.
Not always, but most of the time. Here is the picture of the blank window:

The only way I can close this window, is to click the OK button that appears on the screen.
Clicking on the red X button doesn't help close it.
The window which is approx 5”x4” appears in the middle of my 15” CRT monitor, and can
be moved around.
Once the window is closed, the screen with the single word - Welcome, appears followed
by the Desktop with my icons, folders, shortcuts etc. and all is well with the PC thereafter.
Most of the time the window is blank, except for the OK button in the middle.
On some occasions, a single file path (anyone from the list below) can be seen on the window:
(These file paths are sometimes preceded by tiny blank squares)
C:\Windows\System32\inetsrv\lonsint.dll
C:\Windows\System32\mui\0c0a\xpsp1res.dll
C:\Windows\System32\mui\040d\xpsp2res.dll
C:\Windows\System32\drivers\mskssrv.sys
Six tiny squares followed by ij then another small square followed by w840nd.sys
On one occasion, there were a series of tiny squares followed by r1033tta.lxa
On another, just I-map.sys was present. And on another, just cmd.exe
There are many others, but have not made a note of all of them.
With the help of Mike Lin's excellent startup utility, I have ensured that besides
the AV program there is nothing else that starts when the computer is booted up.
The PC works just fine and I have had no issues otherwise.
Sooo, what could be causing this?

I'm not very familiar with the workings of a computer. So please provide detailed
instructions to enable me to carry them out and post the results.
By the way, I have sought help for this issue on two other forums where I was given a lot of help.
Unfortunately, the problem still remains unresolved.
Grateful for any help from the members. Thanks in advance.
