I run windows XP on a dell optiplex. When I open windows outlook the system crashes and reboots with a message about a serious error. I have reported to MS and get a message telling me of a violation and a possible driver problem.
I also get a message on bootup telling me that HP OfficeJet Com device objects has encountered problems and needs to close.
I can't find any file referring to HP OfficeJet. My only HP printer is a PSC 750 that has worked for years without trouble.
I use Norton Security in case this is relevant.
I have tried a system restore to a week earlier but it makes no difference.
