Not really positive what the problem is at this point, but things are turning out to point to a Hard Drive problem, however I am still checking and have found a small amount of corrosion working its way around the parameter fitting of the dial up modem card gizmo, on the interior, I am at sea level so it is possible this PC may have been the result of damage by sea air, I don't see any anywhere else, but does anyone have any opinions as to what extent this may be playing a roll,

Presently I do have a post for the Registry Failure in WXP, and am looking to Dell for a motherboard diagram to reset the jumpers, but would like to know a bit about anyone's expertise
on corrosion.

In most desktop computers, the area where corrosion would occur is on the bottom of the systemboard as that is where there will be very little airflow which allows the salt to accumulate.

When a PC doesn't want to start, especially one where you do not have any history at all, like this cold fish that came in out of the sea, and diagnostics are limited, you suspect , anything and everything , even the rough knock you gave it when you did not know how to get the tower cover off. Then you begin to wonder if you did something to the machine while you were trying to fix it, finally, . . you think it will never start because an invisible kinetic cold spark has jumped off your body and shorted or demagnetized the system.

The corrosion is to the rear, working its way up the back, from the modem area, . .and looked fatal at first. I try to arrest it.

But after all, . . After a OS re installation. and some jogging, it finally started,

I'm sure that I will find your information invaluable and will get there to log it in.

Thank you much.

The absolute worst; though, is when somebody leaves one of the slot covers off the back and the poor guy has a male cat. That stuff eats up the fiberglass!

In 1981, I had a PT Sol computer brought in which had been mounted on a boat. It had over an eight of an inch of salt built up on the bottom of the main board and it took three times in the dishwasher to clean it off (just don't use soap and no dry cycle).
