Daftar Penyebab: ? Masalah driver yang bentrok atau tidak cocok ? Masalah Video Card, hal ini mencakup video card yang di overclock melebihi batas atau Anda baru berganti Video card dan Anda belum menguninstall driver Video card lama dari chipset berbeda ? Masalah Audio Card, meliputi kesalahan konfigurasi atau bug dalam driver sound card
2. NTFS_FILE_SYSTEM atau FAT_FILE_SYSTEM (0X00000024) atau (0X00000023) Nah, pesan ini setidaknya sudah sedikit “nyambung” memberikan gambaran di mana kerusakan berada, yaitu ada di partisi atau filesystemnya tetapi bukan di harddisknya. Kita bisa melakukan pengecekan dengan memeriksa kabel SATA atau PATA atau bisa mengecek partisi dengan tool chkdsk.
3. UNEXPECTED_KERNEL_MODE_TRAP (0X0000007F) Bila Anda mendapatkan pesan seperti ini, dapat disebabkan karena: ? Overclock Hardware yang berlebihan ? Komponen komputer yang kepanasan ? BIOS yang korup ? Memory dan CPU yang cacat
4. DATA_BUS_ERROR Pesan ini disebabkan karena adanya kemungkinan bahwa memory atau slot memory di motherboard rusak.
5. PAGE_FAULT_IN_NONPAGED_AREA Disebabkan karena adanya kerusakan hardware, termasuk memory utama, memory video card, atau memory di processor (L2 Cache)
6. INACCESSIBLE_BOOT_DEVICE Disebabkan karena adanya kesalahan dalam konfigurasi jumper harddisk yang salah, virus boot sector, driver IDE controller yang salah, atau kesalahan driver chipset.
7. VIDEO_DRIVER_INIT_FAILURE Kesalahan terjadi pada instalasi driver video card yang kurang sempurna, restart pada saat instalasi atau juga dapat terjadi karena kesalahan dalam instalasi driver.
8. BAD_POOL_CALLER Kesalahan ini dapat terjadi karena kesalahan atau driver yang tidak kompatibel. Sering terjadi saat melakukan instalasi XP dari upgrade, atau bukan dari instalasi baru.
9. PEN_LIST_CORRUPT Pesan ini disebabkan karena adanya kerusakan RAM
10. MACHINE_CHECK_EXCEPTION Disebabkan oleh cacatnya CPU, atau yang di overclock secara agresif, serta power supply yang kekurangan daya atau rusak.
