Hello! I am getting a BSOD with "Bad_Pool_Header" when I am trying to utilize my "Nascar Racing 2003 Season" game. However, the BSOD does not immediately appear when I start game, only after "action" occurs. (accelerator, etc.) My machine functions normally and without issue in every other aspect of its utilization, i.e., the BSOD never appears until I begin the game. In fact, all is well even when I first start the game -- I put in the disc; The option screen to "begin" appears; I click on "begin"; the game starts up, I choose tracks, etc., but when I begin any "action" within the game (pressing accelerator more than once, for example), the BSOD rears up. Along with the "Bad_Pool_Header" at the top of BSOD display, the following "Stop" errors appear at the bottom of BSOD: "0x00000019" "0x00000020" "0x84A94B40" "0x84A94CA8" "0x0A2D0008" **I've never had problems using the game at any other time, other than needing a better vid card to upgrade from Nascar 2002 to 2003. (I have an NVIDIA GeForce FX5500 which has always worked fine, and I downloaded and installed the newest NVIDIA drivers for it last night, as I have always done periodically). The only "change" that I can think of was the adding of SP2 to my XP Pro OS. I did the SP2 upgrade a while ago, but had not tried to use the game since the upgrade until relatively recently. Each time, the above described action occured with the game -- I am finally writing to you now because I am TRULY stumped. Again, my machine functions with no issues during regular use, internet use, and I regularly do Windows Update. Did I miss something along the way?? Some SP2 tweak?? I appreciate any and all help you may be able to provide! Thanks much! Jon S.
