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
http://www.sevenforums.com/tutorials/100356-video-card-stress-test-furmark.html 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:
http://www.sevenforums.com/crash-lo...op-0x116-video_tdr_error-troubleshooting.html
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...
