Game crashing constantly with fluctuation in fps and screen flickering.

The game in question is War Thunder; generally the game will crash on me after 3-5 hours of playing. I've had my Lenovo y410p for approximately a year and the original seagate HDD was faulty so I sent it to Lenovo to have it replaced. They replaced with a Toshiba HDD which seems to working fine. The computer wasn't restored to its previous settings as I chose to simply re-install programs as needed.
I run the game on medium although geforce experience tries to optimize it for graphics closer to high/max. The reason I don't play at those levels is that the fps will drop down below 50 which is too low for the game. Usually the game will begin to 'flicker' in the minutes prior to crashing. This flickering is a brief flurry of red 'shapes' or 'lines' (I don't know how to better describe them) on the screen. Before I had issues with Far Cry 3 though I haven't played the game since I received my computer back. My y410p has a Nvidia 750GTm and I believe it should be able to handle these game at medium without too much trouble. I have used geforce experience and device manager to try and update whatever drivers I could but they were all up to date.

Diagnose your GPU.
Did you overclocked it ?
And yes, 750m should play it smoothly in 720p !

How exactly do I diagnose my GPU?
Also the computer is running factory settings so it shouldn't be overclocked.

This may be tricky by try using that card on another known good machine to see if you experience the same thing. Coz there is no such official tool to do that work!

Unfortunately I don't have the option of using my card on a different machine but I did call back Lenovo twice today and the first time the representative used a remote login to access my computer and update the driver (I already was using the most recent driver which I had downloaded through Geforce experience). He told me to call back if the issue persisted and gave me a separate case number from the one which I received for the first repair (HDD replacement). Unfortunately, War Thunder crashed again about 5 minutes after being launched and I ended up calling Lenovo support 10 minutes after the first call ended. The new representative I talked to said I had 2 options: lower the graphics settings for my games (which I already have, this shouldn't be necessary) or buy a new or better GPU from Lenovo.

The rep told me that if my graphics card was to blame nothing would be displayed on the screen when the computer tried to use the Nvidia 750GTm (this computer has integrated intel 4600 graphics and the 750GTm). Is this true, if my card had issues physically would it not display anything at all?

No, Not necessarily..
I had an issue an year back where my display showed a tinted screen, with blue tint over the whole display.
For this the Dell people told me that my GPU was damaged and it needs to be changed. It happened due to inappropriate voltage variations. Because the wire on the display & laptop joint caused the problem!
.
May be your laptop gets overheated during gaming! Did you try using a cooler? Or keep the room temp below 20'c while gaming and see what happens.
I don't think it is a driver issue anymore, coz the red triangles or flickering shows that either you GPU is not able to make the graphics at such speeds or Even ask the Lenovo representative that what if the data lines have been damaged this may be in the motherboard of the system !
Also If it is not a software issue you may have to give for technical repairing..
