Hey guys, so i just replaced my motherboard and cpu and pc doesnt start up, it trys to start up windows but then ends up with a solution to run system repair, do i need to do something like reseting bios? Could be the problem that i plugged hard drives to sata 3 and maybe they are sata 2 or that does not make difference at all? Thanks

You probably need to reinstall the OS.
This is often the case with a new motherboard.

As above, unless you replaced the motherboard with one of the same model or at the very least the same chipset you will have to reinstall windows.

Also because you have changed the motherboard the EULA of windows dictates that you buy a new windows license also.

Often the motherboard is either not recognizing the hard drive/boot order is not correct. Open the bios as the PC is starting up and make sure the boot devices has your Hard Drive listed. Let us know if it works!
