(Solved)Help me, i don’t know whats happening to my computer

Recently, i purchased a Leadtek version of Nvidia GeForce GT 430. While playing games like Crysis 2, C&C Tiberium Twilight and Red Alert 3 at high settings (gamer spec for Crysis 2), i get this problem.
My Specs:
processor : Intel i5-2500k
graphics : Intel HD Graphics 3000 & Leadtek WinFast GT 430 1Gb
hard drive capacity : 1 TB
motherboard : Asus P8Z68-V LX
power supply : Cooler Master 460W
i disabled lucid vitru, if not the problem will be more worse
Look at these pictures. Can someone help me fix it?
Red Alert 3


crysis 2

Answer #1
Update your drivers. Uninstall the ones you have now first.
Answer #2
are you sure the Optimus feature is activated? (if you have it, I think it’s just for laptops though) It switches display from the integrated CG to the dedicated CG depending on the running application.
Are you sure your display is not defaulted to the Intel HD Graphic card? because those look like you are in minimum settings.
Answer #3
Most likely, drivers issues, check for some updates, and google it.. maybe some other person around the globe had experienced, or is experiencing the same issue
Answer #4
Well maybe you have some viruses in drivers installation, so i recommend u to reinstall the windows and all will be fine.
Answer #5
i don’t even know how to describe the problem to google search. my computer does not not have optimus, but it has lucidvirtu, i don’t know what it is but when enabled, sometimes the system won’t boot. I’m not using the integrated graphics, i connected the dvi cable to the graphics card. Maybe i’ll try re installing windows.
Answer #6
You can’t expect too much from a $50 graphics card..
You should be using a much better card to match the rest of your system
Answer #7
Re-install your driver, did you plug in the monitor wire on the motherboard output or on the NVIDIA 3D card output?
Answer #8
nvidia 3d card output
Answer #9
i removed the driver provided by the manufacturer and installed the geforce drivers that i download from the nvidia website. The problem is fixed now. Thank you all for your support.
