One of the files containing the systems registry data had to be recovered
This can someone be the result of bad RAM or Video RAM. Try to change the video memory in the BIOs from the lower number (usually 32MB/64MB) to the higher number (64/128MB) if this does not work try the following below to repair the “NTUser.DAT” file that has become corrupted/damaged on the User Account.
