I don't understand what is the damaged firmware... How can i find the real problem?

I've just tested RAM with: memtest86 but its all ok, I've done a system control launching " sfc /scannow " but nothing... I don't know where I have to look... Someone can help me?

The Kingston memories rarely fail
Why not try to reinstall the windows?
I think the problem is not firmware

[AgentFXA]

Just ignore this error - I see this error every day when I boot the system!
Nothing you can do about it no matter which bios.

I've tried to reinstall windows 3 times... the real problem is where i'm looking a video on youtube or a  film or i'm playing, mouse and keyboard freeze completely, audio lost and video go on fragmented... i can only restart pc by pressing button on case ( anything by software, just tried ctrl - alt - canc or alt + F4 ) and when system restart i take a look on all system registry but i have found only that error... I don't understand what to do to solve problem....

I suggest trying other video card driver.
Or try another video card

[F3d3r1k0]

I can try but i have that video card from past 1 year and it has worked so great.... I don't think video card can be the problem but I can try...

[F3d3r1k0]

I've changed video card but I have the same problem. I have identified the problem, it's onboard sound card, if I disable it all work great. How can I detect if there is a physical problem on the motherboard or it's a software problem?
I've talked with an expert and he suggested me to installing on new hard disk without updates from microsoft ( because they have unified win 7 driver with win 10 ), so we can estamblish if there is hard disk problem or driver problem. He think it can be an overheating problem of onboard audio chip but this it's not sure...

Do you know how to test onboard chip?
