I took out my 3tb HDD to install win10 on this 250gb HDD for a friend the HDD was broke and then I tried plugging the 3tb one back in and it won't post with no signal from GPU and no usb power.

I've tried booting without ram
Resetting CMOS
Taking out GPU
Reconnecting wires
Only booting with CPU

I don't know what to do anymore and I would hate to see this computer be done just because I installed a faulty drive
