I am still trying to find the reason for random crash's. I have the dubugging tools and symbols. I have tried running the tools and have a few questions. 1. I get a few messages when running the following command: c:\program files\debugging tools>kd -z C:\WINDOWS\ Minidump\Mini081505-01.dmp It says that the symbol search path is invalid. I have my symbols in the c\windows folder. Is this the right path? 2. Another error is: Unable to load image ntoskrnl.exe, win32 error 2. Unable to verify timestamp for ntoskrnl.exe Module load completed but symbols could not be loaded for ntoskrnl.exe 3. I also get messages that the kernal symbols are wrong along with a meesage of "probably caused by USBPORT.sys (usbport +9f54) Anyone have any ideas on this? I am running XP with an AMD 3500+, 1gig crucial RAM(tested with 14 passes and no errors on memtest86). I have 2 DVD drives, 2 SATA drives, X-fi sound card, floppy drive. Using a 480watt power supply.
