Unless you meant you can't get them to help for free.
The issue you noted does not sound to me like a monitor driver issue. Did you try this display on another PC or under a Live OS such as you see at

The access denied issue has been the subject of many discussions. I'll defer to those for now since it's unlikely to resolve this. That is, I vote it's not a driver issue.

I have had a 19 in LCD Model w1907 HP flatscreen monitor for a couple of years. It's now out of warranty so HP tech support will no longer help me. Two problems: (1) cannot update monitor driver & get "access denied" or other error message when attempting to do so, and (2) a vertical, one-pixel wide red line has appeared that runs from top to bottom of the screen & it won't go away. Any suggestions about either of these issues. The red line is apparently a hardward problem & it may be cheaper for me to just buy a new monitor, but not sure if this is related to the driver problem. I have the monitor connected to an HP Destop Pavilion using Windows Vista Home Premium (64 bit).
