I also receive a similar message, but I usually get it, if I have had the computer on for quite a few hours, and if I am running too many programs that are using up too much memory.
Perhaps when you start your computer, you are loading too many programs to run in the background that are sucking up your pc's memory...................
I am not saying that this is the answer to your problem, but this is what I have noticed happpens to me
Every time I start up my computer I get to the "Desktop" and the following error message appears:
Rundll32 has caused an error in KERNELL32.DLL Rundll32 will now close
If I click OK the error box goes away and the computer appears to run OK.
Can anybody advise as to what causes the problem and also how do I get rid of it.
Many thanks in advance for any help or info.
