BSOD mostly when playing games

This is my first post here, so bear with me.
I've uploaded the minidumps in the attachment, which has happened for the past two weeks or so. (happened before this, but decided to re-install Windows).

The BSOD happen generally 95% of the time when I'm playing games, or more specific, CS:GO.
I already tried uninstalling the Nvidia driver for 3D sound & visual, no help sadly. I have the latest Nvidia driver as well, and my Windows should be up to date.

Not sure if it makes any difference, but I sometimes, maybe 2-3 times a day, experience a quick freeze & the sound just loops (the past 0.1 second or so). Then everything goes back to normal. I would assume this is because my SSD gets overloaded, or something of that sort. It doesn't affect me too much. I had a similar issue, but that was due to disk I/O (as I had CS:GO on my 3TB WDC green before). now it's on my 300GB WDC Blue.

Any help greatly appreciated.

Counterfeit installations such as yours contained heavily modified code that causes the installation to behave it unexpected ways. Analysing BSOD's and determining their causes on these sorts of installations is very unreliable. For this reason, many analysts won't attempt it.

My recommendation is to install a genuine Windows 7. This will minimise the problems you are experiencing, and make subsequent diagnosis of BSOD's far more reliable. Once you are running a genuine Windows 7 installation, and are still experiencing BSOD's, we will be happy to help you solve them :)

Thank you a lot for your reply, I greatly appreciate it.

My Windows is update as we speak.

Could the disk I/O also cause Skype crashing fairly often? It crash/log-out & says: "Disk I/O failure." - I've noticed this always happen when the SSD is on 100% load & once in a while when it's not.

SMART said perfect for all my drives (with the WD tool & with CrystalDisk Info).

I'll try swapping my SATA cable (have a few spare) tomorrow whenever I get home again.

Again, I really appreciate it.

You have a counterfeit installation, that's the end of our support.
