Mobo won't fit right

[cuziride777]

Hello mates, I am building my PC with an Msi B450 mobo and 2200G Cpu My case is Corsair Spec 01. I am facing a huge problem in installing my mobo as out of those seven holes, I have put four screws right but the other 3 are just not going inside. Tried loosening the other screws but to no avail. The standoffs came preinstalled in the case in different locations. Please help! Thank you!

Are you saying that you cannot move the preinstalled standoffs to align them with the motherboard?

Reason being that the standoffs are too tight to unscrew and move? Do you have a nut (hex head) driver?
