I Recently brought a MSI H61M-P31 (G3) and a i5-2400, 8GB DDR3 1600 RAM, 600W PSU and I'm using a GTX 570 until I can afford a GTX 1060, I've put all components in corrected, tested to see if it will boot windows. However in safe mode, normal and trying to load a completely fresh OS onto it and it would not work. When loading it in safe mode, it crashes on classpnp.sys and on a fresh boot it fails due to a "hardware problem" I have tried loading without a GPU and same problem happens, the CPU gets detected in bios and I've lowere the ram speed to 1033 and still nothing, if anyone could help me it would be much appreciated, also I have ordered new sata cables to see if that could be the problem.
