I have a Compaq Desktop Deskpro EN model ENLP733/10e/6/128cv that I hardly ever use. It sits running. I only have one visual basic billing program that I periodically use. This morning I went to boot it and got an error message that the file windows
2000 root\system32\ntoskrnl.exe was corrupted and needed to be
reinstalled. I booted off of the Win2K CD and tried to repair the disk
with no luck. I believe and I/O error message accompanied this. So i
decided to take the pc apart to clean out all dust, make sure all cables
are seated, no dust in the contacts, etc and then went to reboot. Well
now, I get no image on the monitor and the CD sounds like it is spinning
up and getting warm but all I get is 2 beeps. I have retraced my steps,
thinking that I reassembled the cables incorrectly but I do not think
so. I am not sure. There is a separate cable going to the HD, the CDR
and the floppy drive. is this correct. Then each gets power and the CDR
gets some smaller connectors. i am stumped. I am more of a Mac person so
I do not really understand how PCs go together as well. I do know that
the cable that goes from the board to the floppy is of a unique size and
cannot have been switched by accident. That leaves the CDR and Hard
Drive. If anyone can figure out what I may have screwed up, please let
me know. BTW, I had a couple of spare HD lying around and tried both of
them with the same 2 beeps. I also reseated the ram and video card just to
be sure. Upon startup, it whines a bit and then goes to two beeps with no video. I just need to get it running so I can contact Western Digital and see where I go from here. Please help if
you can.
