Can you please tell me the complete error message?
SD cards not read even though drivers have been installed previously; drivers re-instated.
Windows Action Centre reported no antivirus program installed, even though Norton had been working for a while since upgrade. Tried re-installing; Norton reported a/v was already present
Western Digital, I think....
No, I'm afraid I can't!!! When I said "error messages", I meant things such as a WAC popup to say no a/v installed. As to post-installation MS Office 2010, on startup, laptop states "Windows is loading files", does not boot to Windows, and tries to automatically repair the problem...then states it can't do this automatically and to "contact your system administrator or try again". The only way to boot to Windows is to take advantage of the advanced options and do a system restore to a pre-Office installation date.
I hope this is sufficient info. Do you think the problem is that the system can't cope with a 320GB HDD? Although how this is relevant to Office etc I am at a loss to explain.....
I just noticed,we have the same laptop :)
A system file(s) is causing trouble during boot. System restore doesn't fix the problem, rather it brings the computer to a previous state at which you made a restore point. Looks like at that point there was no trouble.
Boot your laptop with windows CD. A screen would appear after several minutes.It has an option to repair windows.Select it.There is a chance your issue would resolve.If you still face the same problem,I would recommend you to save all your data, create a backup of it in some other USB/portable hard disk etc and reinstall windows. Thanks
