Hi - virgin post so hope it's in the right place! Had to replace Maxtor SATA 250GB HD after it started clicking and BSODs. Now using TrekStor SATA 750GB HD but after installing Win XP it crashed at the very end of the install (XP install seems fine) and has continued blue screening every few minutes since, though works fine in Safe Mode and also has passed every one of the Dell Diagnostic tests (full version). Have installed the latest drivers (at far as I know) for chipset etc, but still frequent BSODs. Have a selection of minidump files - unsure how to analyse them - not always the same message - sometimes involving iastore.sys, sometimes not. Recommended to this site, though I'm not a techie (prepared to have a go). Machine 2 months outside 3 yr warranty - what a pain! Would really appreciate advice on what to do next - have spent 2 days researching to no avail.
