Windows 7: Bsod sony vgn-fz140e

My Sony FZ140E recently started crashing with the BSOD. I've attached all the relevant documentation. It seems to be happening when I'm running many programs at once and/or putting my computer under stress. I did a clean install of Windows 7 x86 (32-bit) about two weeks ago (original OS was Vista Home)...the BSOD did not start happening until two weeks after the clean install. Programs I've recently downloaded are Divx & Xilisoft Video Converter...could these have anything to do with it? If in order to help me you need more information please respond and I will do my best to get the information. There are 3 .BMPs attached with most of my PC's specs. Please HELP if possible. As we all know BSODs are intolerable. Thank you, kindly to anyone who can provide HELP.
