So I've started buying parts for a new PC build and currently have the case (NZXT H440) the motherboard (ASRock 970 Extreme 3) and cpu (AMD 8350 FX). I wanted to use parts from my old PC, the psu (Allied 300w) RAM (2x 2gb and 2x 4gb sticks) and the gpu (AMD Radeon HD 7750) and try to use that for a week until I got other parts. When powered on, the cpu fan and power LED come on, but the case fan does nothing and the gpu fan just kinda nudges forward a millimeter then goes back repeatedly, and nothing comes on screen. Sometimes the gpu fan comes on fine, but the case fan doesn't and nothing shows on the display. The old parts all worked 100% an hour ago in my old PC. Any help is appreciated!

The gpu doesn't have the input on it, it's a low end card, so no need to ask if it's plugged in.
