BSOD caused by GeForce GT 635M with a Code 43

It shouldn't seem strange to you since, as I have said quite a few times and you can see through my posts & screenshots throughout this thread, that the NVIDIA GT 635M comes with a yellow exclamation mark in the Device Manager with a Code 43 and the message: "Windows has stopped this device because it has reported problems. (Code 43)" .
So, how can GPU-Z, Furmark or HWiNFO get any readings out of it since Windows have shut it down? I don't know much but I think that it's like trying to get a Wi-Fi network and you have disabled the wireless network adapter.
And yes, the clock MHz for the RAM is running as I watch it, between 798.7 and 798.9 MHz.

As a matter of fact, the post you linked me on the GeForce forum suggests the direct opposite, that GT 635M is a low power consumption card (35W), compared to others.
The average temp of the GT 635M is around 52 Celcius, according to HWiNFO, when I hit the Sensors button.
I have already ran the sfc /scannow command and it has completed successfully, with a 100% verification.
I haven't ran the disc check yet but will do. Is it mandatory to run it according to option 2, /r?

Hi again.
So I ran disk check (on boot) as instructed in the tutorial and nothing came up. All clear, no problems reported.
I am starting to think about a repair install of Windows... I am all out of ideas...

Hello everyone :).
I am very happy to announce you that my problem is solved! (At least for now... I will come back to that later on).
So, I went on and installed superantispyware and adwcleaner (I already had malwarebytes) and they picked up some tracking cookies and some other dirt e.g. Conduit. I went on and cleared everything up.
From that moment on, whenever I booted the laptop in an offline mode, there was NO code 43, NO yellow exclamation mark, not a thing. That was good.
So I decided to uninstall for a millionth time the 314.22 driver and move on to the 334.89. Call it a hunch, call it psychic, that's what I thought had to be done. All went well, no GeForce Experience of course and still no sign of code 43.
Then I thought that it was a very good time to run FurMark, now that I had the dedicated card working. And that's what I did. FurMark ran great (if 4-5 fps is great but then again, it's just a mere laptop card ). No particles, everything was going well but I had to stop it since the temp built up to 90o Celsius (the warning was set to 100, based on the tutorial I found here Video Card - Stress Test with Furmark but I got scared that it might do any damage rather than good).
But if I attempted to play a game, boom! BSOD with a nasty STOP 0X00000116.
I was very frustrated and disappointed with my choice of laptop since everything pointed to a hardware error. But then, how did the card managed to run FurMark quite decently and didn't crash?
So I started reading about that error code here:
STOP 0x116: VIDEO_TDR_ERROR troubleshooting
and started leaving out the points that I had already tried out. So I finally arrived to this:

Use this technique to "reset" your pagefile:
a ) Go to Start...Run...and type in "sysdm.cpl" (without the quotes) and press Enter.
-Then click on the Advanced tab,
-then on the Performance Settings Button,
-then on the next Advanced tab,
-then on the Virtual Memory Change button.
b ) In this window, note down the current settings for your pagefile (so you can restore them later on).
-Then click on the "No paging file" radio button, and
- then on the "Set" button. Be sure, if you have multiple hard drives, that you ensure that the paging file is set to 0 on all of them.
-Click OK to exit the dialogs.
c ) Reboot (this will remove the pagefile from your system)
d ) Then go back in following the directions in step a ) and re-enter the settings that you wrote down in step b ). Follow the steps all the way through (and including) the reboot.
e ) Once you've rebooted this second time, go back in and check to make sure that the settings are as they're supposed to be.

I should mention at this point that, when I bought this laptop, it came with a single 4GB dimm of RAM and after a few months, I bought another one, EXACTLY the same in timings, etc. (I was searching for about a month to find one). So, when I first installed Windows with 4GB of RAM only, it set the paging file on 1.5 x 4096MB = 6142MB (6144MB should be the correct number but I found it that way, I' ll leave it that way). After the installation of the second dimm, Windows didn't re-set the paging file to 1.5*(8*1024MB). That was ok, I didn't care. 8GB of DDR3 RAM and 6142mb of paging file worked for me just fine.
Anyway, I went on with the above mentioned technique, retaining the same amount of pagefile, and ran for a gazillionth time sfc /scannow. All went well and no integrity violations were found.
Then, I went on and ran CCleaner with everything on the system sector, on Windows tab checked.
Oh boy, and I was in for a treat.
3.5GB approximately of garbage were thrown away and 33 missing registry values (something like that) were deleted.
Since then, I have ran The Walking Dead and Elder Sign: Omens without a single problem (offline games).
I will come back to you (hopefully with good news :crosses fingers: ) later this evening, when I get home and go online for some LoL and Hearthstone.
Let's hope for the best.
Wish me luck...

I have this in mind when buying RAM but the laptop originally came with a 4GB stick and, due to lack of money, I couldn't afford to buy 2 new sticks of 4GB or a new single one of 8GB. So I searched everywhere for an identical stick, I even bought a used one from a same laptop (exactly the same brand, timings, volts, etc.) from e-bay (but wasn't working so I got my money back :) ) but I ended on a G.Skill stick of 4GB, identical to the already installed, except the brand of course (Lenovo installs SK Hynix on their machines, fyi).
Just a new and final update on my problem:
I got home and got online, device manager was looking crystal clean without errors.
But when I hit LoL, bam! BSOD again, error 116, without even logging in the game.
I uninstalled the 334.89 driver again following NVIDIA Drivers - Avoid Problems
AND Drivers - Clean Left over Files after Uninstalling
and I decided to go with this:
Laptops and netbooks :: Lenovo G Series laptops :: Lenovo G780 Notebook - Lenovo (US) (the 64-bit ofc).
Went on and played about 2,5 hours while monitoring here and there the temperature of GPU. I didn't see anything above 80-81 centigrade.
So, to sum up, I believe it was a combined problem of corrupt paging file and malware, maybe just paging file imho.
I hope my (finally solved ) problem will help others with similar ones.
Thank you icit2lol for your guidance and advice and everyone else who got the time to look into my problem and provide me with their advice and suggestions.
Peace out \/
