I changed my page filing according to a guide on the site and then when i restarted i got to the windows welcome screen and loads of error messages came up. One in particular said (LSASS.exe system error an I/O operation initiated by the registry failed unrecoverably the registry could not read in or write out or flush, one of the files that contains the systems image of the registry). There is also another which says windows delay wright faile. Another is (windows was unabable to save all the data for the file c:/program files the data has been lost. This error may have been caused by your computer hardware or network connection, please try to save the file elsewhere). It will say delay write failed for nearly every file on my computer. Please help, thanks.
