Hi all, thank you for reading this post. I have read many issues regarding this but none fit my situation so hope you can help. 4 days ago i turned on my pc and this message greated me, "windows host process rundll32 has stopped working" My options were , close program or let windows search online for a solution. Neither option sorts it but the dialogue box does dissapear untill i next turn on my pc. Now, once the dialogue box has gone my pc runs absolutely normal. No problems or issues at all, so i guess its not a major thing its just anoying that it pops up at start up. I do the same thing on my pc day in day out, updates are are up to date, virus scans are clean, defrag is regular. I pride myself on how well my pc runs. It has been about 11 months since i last had to format due to a program installation issue that windows help and supprt site couldnt help with so i formatted and that sorted it, like i said, no other problems for 11months, but my concern is.... Why all of a sudden is this message popping up? and how do i stop it ? Thanks for any ideas, Kindest regards, Vale. P.S. I am running Vista 32bit home premium, i dont use nero, i have norton 360 v2 and i only have 3D sofware programs in use.
