Re: Frequent Crash of Windows XP

I have appended your original post to this so as to keep all the information together, please include previous if you reply. If you verify that the power remains good the entire time, then the next possible issue that you face is the problem of heat. If the system temperature in the cabinet is too high then you are going to have problems too. Can you document the temperature in the cabinet?

One major difference is also that these systems are in highly tough
environment (that is gas station).

There is no Air conditioning, the machine is kept in an Networking Rack
enclosure which has a fan. No one access the machine directly, it gets
switch on as soon as UPS is turned on every day in morning. In the
night when Gas station is closed, the machine is shutdown by pressing
the power switch once, this way windows initiate the shutdown
sequence.

I hope this information may help.

Hi,

I am facing the problem very often especially at one specific
location...

As mentioned in various posts.. we also suspected the hardware and we
have changed the hardware (infact did it quite a few times). We have
now replaced the complete machine of different brand etc.

The same hardware is running in my office perfectly fine. I have put
the machine on the raw power and left it running for few days. It
works even when the machine is abnormally switch off (due to power
loss) multiple time in a day.

Where as when the same machine with same configuration is running in
the field it carshes very offten with the error messages similar to "C:
\Windows\System32\Config\System is missing or corrupt".

At times I am able to recover the disk from the crash.

I am basically looking for the answer that why does this machine
crashes, where as we do abnormal swtich off (without proper shutdown)
of the PCs in office / home, they don't crash. They why this machine.

Two configurations of the machine which we have tried are -
1. Via C7 Mother board with 1 GHz processor, 1 GB RAM, 4 GB Disk On
Module
2. Intel Borad with 1GHz processor, 1 GB RAM, 4 GB InnoDisk Disk On
Module (HDD), multiple serial ports (4 in number).

Operating System: Windows XP Professional SP2 without any hot fixes/
updates (earlier we were using Windows XP Embedded SP 2 with Feature
Pack 2007, we switched to XP Professional thinking we are missing
something in XP Embedded configuration)

We have tried different make of DOMs, suspecting something to do with
the quality of DOM. We have also tried switching of the "Write Cache
on Disk" option of Windows.

The application that we are running is basically polling multiple
devices on the periodic basis, every few milliseconds. It then writes
the data to SQL Express Database. Application is developed using MFC.

Any answer / tips are welcomed.

Thanks
Rajesh
