I am a beginner, My problems started when I lost my hard drive. Put the new drive in, XP up and running, then notice two things. one could not get back on internet, 2- No sound. I read lots of FAQ and the FORUMS. Tried several of suggestions, no luck. Then I came across this one. CH000876 Missing or corrupt c:\windows\system32\drivers\ntfs.sys. This seems to fit me pretty close because I see both FAT32 and NTFS files. Since I am a beginner at the age of 69 that is not to good. I would appreciate your help. Here is some info. XP Home edition Pack 1 MFG VIA TECHNOLOGIES INC System model VT8367-8235 TYPE X86 AMD 1994 MHz BIOS VERSION PHOENIX 6.00PG 6\18\2003 SMBIOS 2.2 Memory 512MG. Thanks again Deano39
