New Win 7 machine can't see Acer Monitor X223W

Thanks ChrisNeji and 714. I rolled back to an earlier restore point and then again updated Win 7; then went to Device Manager and manually tried to install drivers. However there was no INF file in the zip folder. I could not find anything to load or use. Also, does the fact that my monitor is running on a VGA connection prevent anything happening to a DVI connection? Without the VGA connection I couldn't see anything happening in the machine. While updating all the latest updates for Win 7 after my restore change, I noticed that a ACER update had appeared. I ignored it so as to not affect what I was trying to do but perhaps it might be something that affects this problem.

If you go to Computer>Organize>Folder and Search Options>View>UNcheck Hide Extensions For Known File Types>OK. Then go to the zip file, you will see a .inf file.

I replied last night but somehow goofed and apparently lost it. I rolled back my restore point to a July point as the article said was necessary. I then followed the instructions on updating the driver. But....there was no INF file to which to point. No Vista driver any where. The zip file contained only 3 small files, none of which were useful in providing a solution that I know of. It must be a Windows problem and the advice from 714 and Chris1Neji are right on for the probable problem. But I still can't figure out how to fix it still. ACER wants $100 to provide support but I'd rather put that into a new monitor than give it to them for that. Windows 7 cannot see the monitor in a DVI connection...........that's the issue it seems. Many thanks to 714 and Chris1Jeji for their advice.
