I am getting very nervous. My computer has crashed. It would restart after going through this message -- checking file system on C. This type of the file system is FAT32. After that, it would start ok. But at times, it would give me a blue screen of death -- A problem has been detected and windows has been shut down to prevent damage to your computer. PAGE_FAULT_IN_NONPAGED_AREA. What's wrong? And could anyone tell me how to do a recovery disk to restart the computer? My computer does not come with a recovery disk and i am very nervous that my computer could crashed anytime.
