Your machine is bugchecking/bluescreening. Disable the automatic restart on system failure as mentioned in the previous post. You will also want to configure the box for at least a kernel memory dump so that it will contain some useable information. This is set in the same place as disabling automatic restart on system failure. When your machine bugchecks again you should see a bluescreen with some codes. Check your System Event log on that next reboot to see what the bugcheck code is and that will give you a good place to start googling. My guess is that it is the video driver, since you say this happens when loading many charts. You can try updating to the latest video driver from ATI/Nvidia or go back to the Microsoft inbox video driver for your card, as these are typically the most stable.
Can you help answer these questions from other members on NexusFi?
Oddly enough, I did uncheck the Automatically restart but Windows restarts anyway. I cannot see any blue screen.
I have the most recent drivers for my 4 graphic cards (Nvidia Quadro NVS 290).
I have sent the Windows event log to Sierra support and they didn't find anything that would indicate a problem.

Computers are complicated things and in my experience it absolutely can be that only one program is crashing it. You get the wrong combination of hardware and software and bad things will happen.
I'm an engineer who has constructed computers from the OS and board/chip design up so I can believe it could be a hardware issue.
It is however more likely to be a conflict between Sierra Chart and other software running on the computer. I also have win 7 x64, 8 G of ram, an SSD, HDD, multiple screens and no problems.
If I faced this problem I would do the obvious thing (which I don't see mention of in this thread).
Reformat your disk or ssd.
Reinstall windows 7 clean.
Install only the minimum software to support Sierra and your data vendors software.
Does it fail?
Yes. Then it is hardware.
No. Install all of the other software you want. But take an image of your C drive so that you can quickly get back to this step if a fault occurs. And install the most important things then wait for a few days before adding others a few at a time to find out where the problem is. Maybe store images along the way. The chances are that it won't come up again because Sierra and its microsoft dependencies are interacting with some issue in your earlier software install and removals.
That was one of the first things I've done.
Like I said, I have no problems with my system. All works fine. Only when I open Sierra and load the charts is when the "shit hit the fans" (please forgive my french).
Sierra support say that they can't do anything since it's not coming from them, it's a question of me testing and see what might be creating this conflict.
As advised to me. I even disabled 3 of my 4 graphic cards to see if that could be generating some conflict but unfortunately it crashed again.
I'll rest for now. It's obvious that it has something to do with some hardware which I'm not available at the moment to upgrade. Like I've been saying over and over, my system works fine, without a single glitch with my usual software, it's only Sierra that's generating this problem.
Apparently I'm not destined to use Sierra, at least not with this computer.
Thank you all for your help. It's nice to see people here on a Saturday helping each other.
Thanks.

Download Prime95 and run in Torture Test mode, select "custom" and change the max memory to be 90% of your system memory, change time to run to 5 minutes. Note your threads will be different on an i5 (no HT I think)
This will establish your cpu and memory are stable.
From there, I would download VirtualBox and create a new VM. Don't install a single thing other than Sierra Chart inside the VM, and see if the problem persists.
If your machine is bugchecking, we really need the stop code. You might check the Event Viewer system logs for any helpful errors as well. If it is a hardware error, there may be precursor log entries.
Have you established that it is nothing specific to that exact chartbook?
Create a new chartbook, and create a simple chart with no indicators. Then duplicate the chart 20 times, and save the workbook. Make sure you are using the same lookback historical settings. Then exit and reload Sierra a few times, does it work?
You can also post your chartbook, I can load it here and confirm it loads fine. I assume that Sierra had you do this already and they were able to load it no problem?
Also please don't quote inline inside someone elses quote, because then it makes it hard to quote you when I reply.
I did run Memtest86 but no error was found. Never tested Prime95.
I actually never worked on a VM before. Years ago I was tempted to install one so I could "play" with Linux but time started to get short and I just "deleted" the idea from my mind. I was already spending too much time in front of the computer, I didn't need to add more work to it.
This problem with Sierra could give me the opportunity to work on a VM but to tell you the truth I'm a bit tired of testing stuff just to make Sierra work. The time I've spent testing stuff has already cost me a couple of hundreds bucks. By now it would have been cheaper to buy a new SSD and RAM.
I've lost count on how many chartbooks I've created.
Sierra support didn't find any problem with them.
If you want, here are 4 chartbooks for you to test.
Regards.
