I got my laptop before this computer im on now (desktop) and my laptop is a little older and it has windows 98 installed. Well, at the time I really didnt know anything about computer memory and how it all works, so one day i tried to install something on my laptop and it said i needed more memory so I then started to erase everything (including some system files) because I thought that would clear enough memory so i could install it but now i realize it wouldnt of. So everytime i try to start my laptop, it wont even let me go to the desktop. It goes to the command part. and it says "The following file is missing or corrupted: C:WINDOWS\HIMEM.SYS The following file is missing or corrupted: C:\WINDOWS\DBLBUFF.SYS The following file is missing or corrupted: C\WINDOWS\IFSHLP.SYS Type the name of the command interpreter (e.g.,c:\WINDOWS\COMMAND.COM) It says something is wrong with the registry. Please help!
