Both errors are the same 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. They can also be caused by bad RAM.
Nothing definitive was cited but we note that you are still running XP with SP2. We here at TechSpot strongly recommend to everyone running XP to update to Service Pack 3. Why? Three reasons: a) XP with SP2 is no longer supported, b) for critical security updates, and c) for stability.
Just yesterday I was helping someone who was experiencing system crashes due to software drivers. I noted he was still running XP w?SP2 and said try updating to SP3. Sure enough it brought stability. I am not saying this will work for you but with XP it is still an essential thing to do. If anyone tells you SP3 will cause issues tell them that is very old news and not the case for some time now.
