This is a long story and I’m not sure where to start. I’ll start with the problem THEN explain what I’ve tried (for those who think they can help and want to keep reading). PROBLEM: I can’t get online. Icon in taskbar says I don’t have a network connection. Upon exploring, I find that Windows 7 Pro has me setup for a “public network”—which has a yellow exclamation mark on the left side between my PC and the network, and a red X on the right side between the network and the Internet. DETAILS: Dell desktop PC. Was running Windows 7 Home, now running Windows 7 Pro (full install; not upgrade). I had a malware problem (images on webpages and links, etc. were not visible to me) with W7Home; cleaned it and went to W7Pro. However, now I have this whole new and far worse problem with W7Pro. (See “problem” above.) NOTE: I am the only person in my house and the only person using the computer. So I never had it set up for a network. I only own the desktop PC and don’t need a network. The “network” that is now set up on my computer was set up by W7Pro by itself as part of the problem. My IP is not static so I can’t input my IP manually—it’s set to automatically detect. Called cable modem service provider; they made the assumption my operating system came with my PC and told me to call Dell for support. When I explained my OS didn’t come with the PC, they then said “You need to talk to Microsoft.” Uh---no. The cable modem service provider said their server is talking to my PC…my PC is unable to get to them. (Makes sense, as that matches the pictures I’m seeing with the exclamation mark and red X.) TRIED: Researched online. Followed all possible fixes found in multiple forums. Removed Bonjour. There is now no trace of Bonjour on my PC. Disabled Windows Firewall. Tried disabling, enabling, etc. numerous times. Tried diagnosing, etc. No LAN connection. Network is set to Public and I can’t change it to Home. I don’t even want to change it—I want to REMOVE IT as I have no use for a network. Can’t figure out what to do. Yesterday I booted to CD and installed W7Pro again, hoping to get rid of the problem. No change. I booted to my Dell disk to revert back to W7Home, hoping to get rid of the problem. No change. !!!!!!!!!!!!!!!!!!!!!!!!!!!! L I even tried to go all the way back to W95, but the PC wouldn’t let me. (I have 64-bit on this PC; assume that’s why as the old W95, W98, ME, and XP disks were for 32-bit PCs.) HELP NEEDED: What can I do here? Any ideas? I’m at a complete loss. I need to delete the network somehow? I need to figure out what’s blocking me from getting to the Internet so I can get on. Or I need to delete W7 from my PC so I can install it again from disk---otherwise reinstalling it from disk over the old version isn’t changing my settings. L Is it even possible to go to C and “format” like you could in the old days…and if I did, would it then not boot from the CD? (Or recognize my keyboard, as the first thing it says to do when booting is press any key to boot from CD…) I’m desperate. This purple Dell computer has become a darned EXPENSIVE paperweight!!!!! I’ve been offline for 3 weeks… Oh…and I can’t run any diagnostics and save the info as I can only get online at work M-F. Any helps is appreciated!
