Yesterday I connected a new external hard drive to my PC and copied all my stuff. Got a message saying all successful except something called "omibox" (I think).
Now I cannot access th internet via google Chrome or IE, I know my internet connection working as I am using it to post this.
Try a portable browser. Download to a flash drive from another PC then connect the drive and run the .exe. Portable firefox.
If ok then you can try uninstalling Chrome and then reinstall. In Internet explorer go to tools, cog icon, internet options, advanced tab and reset interner explorer. If all fails try a system restore.
