Hello everyone! 
I recently ran into a problem with my PC not posting after installing motherboard drivers like built-in audio drivers and Intel RST drivers. And the same thing happens whenever I try to overclock my CPU (even without any drivers or OS installed). The PC powers on, but nothing happens, there are no beeps or anything like that. But when I disable the built-in audio and some other components from the bios, my PC boots normally...
This problem occurs with both Windows 7 and Windows 10. And everything was running fine just a few days ago.
My PC is almost 5 years old and it runs on a Intel 990X CPU on a Gigabyte X58 G1.Sniper board which is powered by a Corsair 1200watt PSU. It recently went through some upgrades including an upgrade to a GTX 980Ti and an Asus Wireless AC card.
What are your thoughts about this? I would really appreciate some help with this.
P.S. I'm sorry about my bad English.
