Out of the blue...my desk top computer at home stopped working...a message that the hal.dll file is either corrupt or missing came up... I tried pressing F8 at start up in order to go back to the last known good configuration...it didn't work.. I tried booting from my XP CD...going to the recovery console...selecting repair..and running bootcfg /rebuild...that returned a message that there was an error, "Failed to successfully scan disks for windows installations. This error may be caused by a corrupt file system, which would prevent bootcfg from successfully scanning. Use chkdsk to detect any disk errors." Soooo, I ran chkdsk....and got a result saying that the volume appears to be in good condition and was not checked. Use /p if you want to check the volume anyway. Which I did. It gave some kilobyte reading and returned me to C:\Windows> So I am lost... Any ideas?
