I ran Memtest for 10 cycles w/o any errors at all. Also changed hard disks, reinstalled XP home to a different samsung HDD but SATA and changed the graphics card to 1950XT. Downloads new drivers for Graphics card and motherboard but still getting intermittent errors. First time round used Abit firewall and had no anti-virus. Second time used windows firewall and McAfee Suite but still happening. Rarely get same BSOD message more than once. Tried RAM in different slots. More than powerful enough PSU, brand new, no dust. Using Antec Freezer but not overclocked and CPU runs at 27 oC. Included some minidump files, can anyone help??
