It seems the problem was related to my printer's software package - HP OfficeJet J5783 All-in-One. A service called "Net Driver HPZ12". After disabling it - and installing IE8 - my screen driver started working properly, and IE started working again.
However, now there is a new problem with my wireless USB LAN card (next wireless card I buy will will definitely be PCI), model: Edimax EW-7318Ug - if right click on the connection icon in the system tray and select repair, I always get the following message: "...The following action could not be completed: Disabling the wireless network adapter. Make sure your network adapter is probably installed". Initally my friend disabled the "Wireless Zero Configuration" service and configured the manufacturer's utility to manage the connection. Then I enabled it again and configured Wireless Zero Configuration Service to manage the connection. It didn't help. I tried reinstalling the driver for the card, but no use.
My question - how to solve this?
The connection seems to work OK, but it worries me that I cannot repair it if I need to.
Thank you very much for your time,
Edit: When I right click on the icon and select just "Disable" I get the following message: "It is not possible to disable the connection at this time. This connection may be using one or more protocols that do not support Plug-and-Play, or it may have been initiated by anther user or the system account".
I'm not sure what it means. I only have one user account on my computer, and I installed it regularly (from the disk I got with the card).
