Hello, first post on here. Looking for help please. Desktop pc has recently begun showing Blue screen and rebooting whenever certain programs or activities are attempted. Whenever I try to open Creative X-Fi I get BAD_POOL_HEADER ***STOP: 0x0019 (0x0020,0x894D3DA8,0x894D4478,0x88DABC90) Intervideo WINDVD4, causes BAD_POOL_CALLER ***STOP: 0x00C2 (0x0040,0x0000,0x8000,0x0000) Any game or music cd placed in the cd dvd drive causes, BAD_POOL_CALLER ***STOP: 0x00C2 (0x0040,0x0000,0x80000,0x0000) I'm not that clued up on computers so this is a bit over my head. Can anyone please tell me how to fix this-in very simple language, as right now I cant play games at all on this pc. Thank you in advance for your help.
