Okay, before I get flamed about this, I do realise that there were posts similar to this one made quite recently. Unfortunately the solutions suggested in these have not worked for me. This is not surprising as the category 102 system error can be the result of quite a number of different things going wrong as I understand it. Symptoms: I also experience the blue screen, the restart and discover the category 102 system error in my event logs. This happens every time I place my machine under load (I'm busy stress testing a web application). Specs: P4 2.8 Ghz, 512MB Ram, Win XP Pro (SP2) I've tried: 1. Reading the minidumps by following the instructions posted by cpc2004 in another thread but failed to do so as it kept on complaining about symbols. 2. Running memtest - nothing to report. I'm attaching my minidumps in the hope that someone will be able to read them and help me out. I'm at my wit's end Edit: This may or may not be relevant. VMWare was recently installed on the machine.
