well...system pulled another one on me...weird thing is, when my laptop has new 1 GB stick installed and old 512 MB stick installed, laptop is working fine...when I have both of the 1 GB sticks installed, both are identical, my laptop is going crazy, giving me all sorts of errors, i.e. PAGE_FAULT_IN_NONPADED_AREA, AFD.sys error, and today it gave me ntfs.sys error...now I'm working with 1 GB stick and 512 MB stick...attaching more minidump files and also, I ran EVEREST home edition and took out a report of some specs of RAM and MOBO...can someone please help me out with this...my Dell Laptop has never done this and i've upgraded memory on it before, but now trying to max it out @ 2GB (per a system scan on crucial.com)
