Boot up and shut down error messages

by gracefilled / April 10, 2007 12:41 AM PDT

We have an Hp Pavilion 1210n with windows xp media center edition, 2002 sp2 which we just had to take in and have a new motherboard and hard drive installed. We just got it back and installed the operating system. It worked fine but I began installing our software that I had on before and started getting error messages now everytime we shut it down or boot up.
The one we get right after booting up is "The instruction at 0x0040da9 referenced memory at 0x00000004 The memory could not be "read."

On shutting down the last time I got fspex.exe
and dwwin.exe...initialization failed
Then I get a box asking if I want to end the program now. I click end now and it finally shuts down.

What is happening? Did something get damaged in installing programs? I installed so many yesterday that I don't know exactly when this happened. I tried using the system restore after I noticed it but this did not correct the problem. should I restore to another restore point before installing all my programs? (*sigh*..sure hope not)
Not sure how to fix this problem. Otherwise everything runs fine and works like it's suppose to.

Help would be appreciated!

fspex.exe is your F-Secure Anti-Virus Updater. You might want to fetch their latest then uninstall then reisntall this AV when you are offline.

Once that's out of the way, try again. If it fails I head to the EVENT VIEWER (see to clear all events, create the error again so I can see what may have caused it.

F-Secure Antivirus Problems?
by Grif Thomas Forum moderator / April 10, 2007 12:58 AM PDT

The "fspex.exe" listing is for your current F-Secure antivirus program.. The "dwwin.exe" is for the "Dr Watson" program in Windows which monitors problems on your computer and attempts to notify you of them.

If you've got a bad installation of F-Secure, it might be causing both errors.. What happens if you uninstall F-Secure?

Hope this helps.

And Have You Visited Windows Update??
by Grif Thomas Forum moderator / April 10, 2007 1:00 AM PDT

If not, please do.. In addition to important Security Updates, there are a number of critical "fixes" for the operating system which might help eliminate some of those errors.

Hope this helps.

Found the problem
by gracefilled / April 21, 2007 2:55 AM PDT

Just wanted to come back and tell you all what the problem was. I tried updating, and uninstalling my security suite. Nothing helped. It eventually got so we could not even get online. We took it back in to Best Buy, they hooked it up, it worked great there for error messages and no problems. They got online fine. He said he thought it was our modem and to go home and reboot the modem. We did and everything works fine. I'm relieved the problem was the modem and not the computer. All is well now.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
