No BSOD, just restart in the middle of anything and everything. 14 crashes on 10/29/06, various debug causes including savrt.sys (NAV 2006), memory_corruption, win32k.sys, ntoskernl.exe and classpnp.sys. I uninstalled NAV 2006 on 10/30/06 and only 2 crashes, debug causes: savrt.sys and win32k.sys. One crash on 10/31/06, debug cause: win32k.sys. Installed NAV 2007 11/1/06, 4 crashes, debug causes: srtsp.sys twice (maybe NAV 2007), win32k.sys and ntoskrnl.exe. I have attached the 4 minidumps from 11/01 and debugs w/analyses. Before 10/29 I changed out my 256 RAM for a 512, and it's made it much faster but not fixed the crash problems. Every time I send the error report to Microsoft, the OCA says it's a device driver unknown or a video device driver. I have the Radeon 7000 series, and I updated a driver from 5/3/2006! Obviously I could uninstall NAV 2007, but I don't know if that'll fix the win32k.sys and ntoskrnl.exe. I can't pinpoint it. Help, please. Thanks! 
P.S.: It crashed this morning once with the srtsp.sys being the "cause."
