Do you hear it beep on start up? Did you reformat the hard drive that has windows? If Not that could be a big reason why your having all the problems you're having. If you left windows from ur old machine your gonna need to wipe it.



You'd have to follow both you're case's manual as well as the motherboard for all the bottom hook ups that go from the case to the bottom of the motherboard.

Than you should consult your power supply manual and the motherboard manual for the right hook ups. Certain power supplies have certain ways especially if they have multiple rails, its highly important.

Okay. am gonna remove everything from case and try again with manuals.

No need to format anything. You can actually use an old windows installation for a new PC but it is not recommended as it can cause problems. The easiest way to find the problematic part is to remove all stuff that isn't needed to go into the bios screen(HDD, DVD-ROM). After that reset the bios either with the button for it(if there is one) or by removing the bios battery for a few seconds. Then you might want to check if your GPU's fan spins up. You can also try a different PCIe slot for the GPU. Make sure all power inputs on the mainboard and GPU are connected. It might also be a loose contact so try moving the connectors a bit when the PC is off.
