system restarting by itself

Tara14

Hi, I have created an application in vc++ using mfc. The application connects to Access database. I have used DAO. The application is multi-user one. It works like this: When the user creates a new account, a new .mdb file is created and then two tables and fields are created at runtime. It has editable listview control, graphs -pie chart/bar graph, a password-hashing algorithm. Some of the class I got from CodeProject and then modified them to my need. The program does not use registry keys or any complicated programming. I did most of the program on one xp system. I had to change the system due to some reason. When I was working on the new XP system, the computer would restart by itself. It wouldn’t happen at regular intervals. I assumed that there was something wrong with the system. After a while it totally crashed. I switched back to my old system and completed the program. When I send it to a friend, he worked the program for a while, after which his computer too started restarting by itself. I worked the program on two other systems, but nothing happened. I am wondering why is the system failure occurring on some systems. I just can’t understand whether it is my program that is causing this to happen. If so, why is it not happening in all the systems? The program does not use the windows registry or any complicated codes. If anybody knows about this please help. Thanks, Tara_

Have you checked if the memory is OK? Try memtest.

Please can you tell me which memory.

I do not know about memtest. Please can you explain in a little more detail. Is the problem with my program?:confused:_

Look at http://www.memtest.org/. This is a tool that checks your RAM. It happens that programs crashes without an obvious reason. In that case it is useful to check the memory to exclude a hardware problem.

Why is it that it on the two system that I worked on nothing happened, but on a third system, the same program is behaving this way?_

What do you mean with "system"? The OS or the hardware?

Tara14

The OS,I guess, Windows XP_

This is what is showing on my computer that crashed.

Windows could not start because the following file is missing or corrupt:
\system32\hal.dll
Please re-install a copy of the above file.

Did my program cause this to happen?_

Just google a little bit.

I did google. Mostly what comes up is: people have the same program. They are told that it is because the system heats up too much or because of windows update restarting the system. Thins like that. I need to know whether there is something wrong with my program. Is there any remote possibility that my program is causeing this? I am finding it difficult to figure it out because on my system the program works fine. Its working fine on another computer too. Does that mean anything? That nothing is wrong with my program._

So have you ruled both of these possibilities out?

I do not know what to think. I managed to reinstall windows on the system that crashed and worked my program again on it for a long time and nothing happened. It has not restarted at all. So I am totally confused. The program has to work on the clients system..._

You would have to be doing something awfully odd to crash a properly configured XP system by anything you're doing. On the other hand, this is MS; if there is a way to 'tard something up they'll find it. What exactly did you have to change on your system? Do these systems that are crashing crash under heavy load from other apps? Do you have spyware / trojans / viruses on these machines?

No. The sysems are properly protected.

That is exacly what I thought too. And my program uses all the usual very simple dialog boxes, some calculation, no registry used, no dll's, no multiple threds, no internet connection.... I have added

AfxGetModuleState()->m\_dwVersion = 0x0601;

at the begining to connect to dao360. The best part is that on two other system no restarting has happened. But of course, the client is going to blame my program if his system crashes.:((_
