Everytime i try to print..it gives me the message "windows host process (Rundell32) has stopped working." What should I do?

Try to uninstall the Lexmark driver then download an updated driver online: http://bit.ly/SvsdMn

Please make sure to allow full access to all Lexmark software/ printer communication processes in the programs rules/ permissions for your firewall.
You can also try to update your printer software by downloading the printer driver from the Lexmark website at http://bit.ly/oLDVDp. Select your operating system > click on "FILTER" > click on the driver under Recommended Downloads > download and execute the file. Simply follow the instructions on your computer screen to complete the installation.
After the re-install process is successful, try to open the Lexmark Solution Center again to verify that the problem is fixed.

No, the error message you got was "generic host process", not "genuine" host process. And in any case, that error could be caused by a thousand different things. Therefore, re-ask your question with more details about the things that you were doing when it happened.

yes sometimes it does it to me but get a reparist man or go inside the moniter/computer to see.

If its called rundii32 and not rundll32 then you have malware run this program its free and really good.

I guess it is a network virus! Repair your os, or reinstall it if needed , and do not share anymore or buy a Total Security antivirus!

Turning off thumbnails will probably stop you getting that error

DO:
Open Control Panel > Folder Options > Always show Icons, Never Thumbnails

However, this isn't actually fixing the problem.

Do you have Nero installed by any chance?

If so try:
Open Computer > System Drive > Program files > Common Files > Ahead > DSfilter.
Rename "NeroVideoProc.ax" to "1NeroVideoProc.ax"
Also rename "NeVideo.ax" to "1NeVideo.ax"

And then reboot.

Reinstall MSN messenger, and your browser
