[PC] blocking my control cars and turns itself

This is what i was just writing a 3d about.This is a big problem thanks to which mostly I abstain from doing races with other ppl because in pretty all race I do, my keyboard keys randomly stop to respond and i crash on walls, stop to accellerate, etcetc.. every bind i do, rly annoying. Tried also all the tips posted previously about adjust joys death zones etcetc but no way, randomly it keeps happend.

it's really stressful bug, you wanna play the game but you cannot because of bugs... -_- annoying 

on EA Live Chat Support, I also wrote why when I played nfs trial game so I ran it steady 50-60 fps (at the lowest detail) and when I play the full version so I have a problem to have stable 30-40 fps (at the lowest detail), he told me that the trial and the full version is completely different. How when trial and full verion have a same size so how it's be completely different? I don't understand....

My pc spec:

GIGABYTE Z77X-D3H
Intel Core i5-3570K
Nvidia GTX660Ti 2GB DDR5
Kingston Hyper X 8GB DDR3

I know that do not meet minimum requirements of NFS but as I wrote in trial version i ran it fine. I know my pc spec are already old but he holds and I can still play some AAA titiles on medium or high details...  definetly it depends on how developers to optimize the game.

Thank you EA_Tom for your answer but unfortunately not solve my problem and probably needs to be investigated elsewhere.

Just to report

My PC is 2 weeks old, just assembled and here the specs:

• Case: Corsair Obsidian 900D
• CPU: Intel Core i7-6700K 4,0 GHz (Skylake) Socket 1151 - Boxed
• PSU: Corsair HX1000i High Performance - 1000 Watt
• Motherboard: Asus MAXIMUS VIII FORMULA, Intel Z170 Mainboard - Socket 1151
• GPU: Asus GeForce GTX 980 Ti POSEIDON, 6144 MB DDR5
• RAM: Corsair Vengeance LPX DDR4 PC4-21300, 2.666 MHz - Kit 16G
• Storage: 1x Corsair Neutron XT SATA III SSD 2.5 ver.B - 240GB
• Cooling: XSPC Kit Water Cooling RayStorm D5 Photon RX480 V3
• Audio: Asus Strix Soar 7.1 Gaming Audio Card PCIe
• SO: Windows 10 Pro OEM

There is nothing else installed except drivers, origin, steam, kaspersky and my Thrustmaster T500. As mouse i use a RAT7 and as keyboard a Corsair K90 that i use currently in NFS.

To me this problem happend randomly, sometimes yes and alot, other simply not but is very annoying and happen ever as mentioned above when pressing more than 2 or 3 car controls binds. to me happen mostly when i press brake+steer L or R= Steer key stop working and need to be pressed again in order to work // Or // Accellerate + steer L or R + NoS = Steer key stop working and need to be pressed again in order to work. When I close>reopen NFS the problem tend to disappear.

 I have to agree with Knor_999 I tried a few solutions that wold maybe can solve the problem but it's did not work. And when I wrote about this issue on EA Live Chat Support they told me that this is a bug in the game, but i am not sure if it's true. But I think yes, because in other racing games i don't have this problems.
