PC problem , need help
So my PC randomly shut down and when I started it it ran windows startup repair and tried to fix my files. My brother took the PC apart and concluded the hard drive did its days, we got a new one , booted windows 7 and everything like last time. 2 days ago mid game my keyboard lost connection ( didn't even touch the damn thing) and since it is a PS2 keyboard I had to restart. Yesterday my keyboard didn't respond at all, it flashes on startup but nothing more so I had to do system restore without it. Today when I started the PC the mouse didn't respond (USB mouse) or should I say move because clicking work and it did light up so it has power. Any of you know what a problem could be, my idea is the motherboard but I am not sure
