I need to find out, why the system crashed on those days.
Thanks for help.
Both error codes are 0x00000019: BAD_POOL_HEADER
A pool header issue is a problem with Windows memory allocation. Device driver issues are probably the most common, but this can have diverse causes including bad sectors or other disk write issues, and problems with some routers.
Nothing was definitively cited as the cause. However, we note that you are still running XP with Service Pack 2 and we here at TechSpot strongly advise everyone who are running XP to update to Service Pack 3.
