BSOD when playing games (BCCode: 116)+multiple components failure

I recently got a problem with sudden BSOD when playing games such as Armed Assault 2 and DCS A10.

The problem seems to have build itself up over time.

The BSOD:

The BSOD is similar to other issues on this forum, with sudden stuttering sound, freezing and black screen, and then the computer restart itself. There seems to be no triggers to the cause as it happens at random times within a minute or two ingame. (meaning, looking at things in game that puts pressure on the graphics card doesn´t trigger the BSOD)
When the computer reached the desktop, I got this error message:

Short Version:
Problem started when playing games, giving me BSOD after about a minute ingame.
This evolved into not being able to get to the opening credits when starting games, and later on even the screen image at the login page would not show.
What follows is trying to uninstall/install graphic drivers through safe mode, and when successful with entering normal mode. this was successful in some degree, but after restart nothing was changed.
After some trial and error with the "graphics driver" tip, the safe mode could not be entered with the "classpnp.sys" hang, and entering the computer in normal mode, was randomly successful with limited availability. Trying to watch youtube videos, .gif images, pictures and so on resulted in BSOD, so the computer could not be used, strictly speaking. After a while it went back to not showing a screen image at the desktop login page.

Trying a different PSU as a tip I got from reading a thread on this forum, my two HDs (SSD+standard) would not be recognized at boot, ´nor in the BIOS, leading to a "insert boot device, and press a key" message when starting up the computer. The message persisted when reinserting my own PSU.
Ejecting the DVD/CD is not possible without destroying it, but it is showing signs to be alive by blinking.

I have not done anything more with the computer since the last issue, and the only thing I can successfully enter is the BIOS.




Detailed Version:
It first started with a "simple" BSOD when ingame DCS or ARMA. The BSOD itself has been described above.

I then tried to figure out the cause of the problem, the "when, what and why". After a couple of BSODs, the screen suddenly would not show anything when reaching the login page after restart.

-I got a tip that this might be a driver problem, so I restarted the computer in safe mode. This worked well, but the screen driver could not be uninstalled via the "remove applications" tool within the control panel. I then tried to uninstall it through the hardware manager, disabling it. This was successful, but after restart again the driver was still installed.
I managed after lots of restarts to access the desktop in normal mode, and then I uninstalled it through the applications manager. This was successful, but the typical flickering with the screen when uninstalling a driver, and the corny image that usually follows was not shown (the driver was removed from the menu, and thats it).
So I restarted, hoping this would work. The driver was still installed somehow, but now, when uninstalling the driver, I get up an error message (I do not remember the contents of this message), saying the driver can not find a certain file, and that the uninstaller will now quit. I did not get the nVidia uninstall screen, only this message.
After lots of trial and error with the tip that this might be a driver problem, the computer went back to the issue with not showing a screen image as soon as it reaches the login page, but also accessing safe mode was now impossible (hangs at classpnp.sys), meaning the dump file and similar diagnostic aids is unavailable.

I then searched for help in this forum, and I found a thread covering the same issues I had, saying the GPU or PSU are the issues here.
I wanted to try the same things so I contacted a friend of mine, wanting to test his components up to mine as to diagnose what component causes the problem, and then replace it.
Yesterday I tested his 850W PSU and after this neither of the Hard drives are recognized when booting, ´nor in the BIOS.
Now the computer doesn´t even reach the login page, as it is either stuck with the message of inserting a boot device and press a key.
So we tried inserting the Win7 CD but the CD/DVD reader will not open. It is recognized in the BIOS, and it is blinking, but will not open.

I have not done anything more since this, but I am considering buying new components for the computer, but I need help with the following:


Solutions Outcome:

1. If there is a solution to the whole issue, then that would be the best result, offcourse.

2. If it is possible to diagnose what component/s is causing these problems so I can replace them, that would be the second best outcome.


Thanks!

BTW: I am not very well known to computers outside the OS desktop and such, so please be prepared for follow-up questions on your replies.

Thanks for your reply. I saw the link earlier, but still a bit too late I´m afraid, since now the only thing on my computer that I can actually access is the BIOS, but I got an update on the issue as to diagnose what component might be causing the problem.
I checked with another forum and they said this might be a Motherboard issue, since now the CD drive and HD disks are not working at all. The CD drive is recognized in the BIOS, and it is blinking-showing signs of life- but it wont eject or come to life when forced open...


anyways, I did some testing today with removing different components in the computer, and what I got, in short, was that the memory card seems to play an important role in whether the computer starts or not.
I started the computer with everything except cooling fans removed and it would not start properly, running up for 5-6 seconds then shutting down and trying again.
I inserted the memory cards and the computer runs up until it reaches the "insert boot device" message half-way through the start up process.

inserting the other components made no difference. I am not sure what this means, if this is normal with the memory cards removed...

I could try that, but it might take some time for me to borrow some though. Rather that than to spend money on a new motherboard when it´s actually working.

But it sounds like a MB problem to you?
Could the MB start the problems as mentioned in the original post, with the BCCode 116 and everything?

Excellent suggestions, and reasoning. Atleast we are getting somewhere. I will try this in the morning.

I tried starting the computer with the CPU removed. It would not start, only running up for 1-2 seconds then shutting down.

I also ran the memtest86 for 18hours+ with no fails, so I guess the memory cards are working fine?

Is it possible that the x116 code may be due to an outdated component, for example that the Motherboard has not been updated? I cannot remember the last time I updated the MB driver.
