Without any disks in the computer I started it, the IBM Aptiva screen
flashed (showing press F1 to go to Startup Menu, which when pressed
previously will take me to the Startup Menu which shows all info regarding
the computer) and then goes to the following menu showing 1. Normal, 2.
Logged (\BOOTLOG.TXT) etc. with:

5. Command Prompt Only highlighted. A message below that reads: "Warning:
Windows has detected a registry/configuration error. Choose Command Prompt
Only, and run SCANREG."

I click return on Command Prompt Only (When I click on Safe Mode I am
brought to the same following screen) and the message reads:

"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

C:\
Cannot find WIN.COM, unable to continue loading Windows
C:\"

At the C:\ prompt I type in SCANREG and hit return and get "Bad command or
file name" and below that the C:\ prompt shows again.
