I've had several BSOD recently and had posted some info in an earlier thread but have had no success in tracking down the problem. The latest BSOD is: The problem seems to have been caused by the folowing file: Ntfs.sys Page_Fault_In_Nonpaged_Area Stop: 0X00000050 (0XFFFFFF0F,0X00000000,0XB963E126,0X00000000) Ntfs.sys-Address B963E126 Base At B9616000, Date Stamp 41107EEA. I've had a look at the latest minidump and although I don't really understand what I'm looking at, I think the last BSOD could have been caused by my anti-virus (AVG Free). Hopefully CPC2004 (or somebody else with experience of these problems) could have a look at the minidumps and perhaps offer some advice, or confirm my interpretation as to the problem being with AVG. Thanks in advance.
