Can't install drivers after clean install W7

[justin18]

I bought a new laptop 2 days ago and it came with Windows 10. I really hate W10 so i did a clean install from a USB 2.0 with Windows 7.

After configuring the BIOS and installing everything i can't install my drivers because my freshly installed W7 doesn't recognize USB.. It does powers them because the lights blink but i can't see them in Explorer.
I tried to go to 'device manager' in Testing mode and installing the drivers from System32\Drivers and the system can find them but can't install them. So without these drivers i'm unable to do anything!

Any help?

Thanks in advance

If you remove your USB and plug it into another computer does it work?

Ensure that the USB is in the correct format, I believe it's FAT32. Also different USB ports on the machine.

Tried the USB already in other PC's and different formats.. Works on every PC except this one. Can't even use the SD card reader from the laptop.

When i go into device manager there is a yellow triangle near the USB icon. Can't right click and update the driver because it's not trusted by Microsoft even with the bcdedit command already on.
