I have just purchased a new Dell pc for a client's home with Windows 7 Professional (32 bit) installed. After installing some basic apps (office/skype/itunes to name a few), I have a problem that occurs. The symptoms are, internet explorer will not open (shows as running in task manager), the network icon in the taskbar has the rotating 'egg-timer' on it and reports no network connection - however, I have been diagnosing using LogMeInRescue so there's obviously a connection working to some extent! Also, the network and sharing center doesn't open to add to the case for a network issue of some sort.
I can successfully use system restore to go back a day or two and the problem is again ok but soon re-appears (within 24 hours). I checked the event logs and saw a few warnings/errors relating to a printer driver which I have since removed but the problem is still there. I've run a full scan using avg in safe mode with no problems reported.
Any ideas please?
