I've got a new build that I'm struggling with. It has worked intermittently, but never reliably. The longest it's worked is for a week, and then it won't turn on again for a while, until it does. I haven't been able to figure out the problem. Today I took everything out of the case to test things. I had the motherboard, one stick of RAM, and the GPU, and monitor all plugged in and it booted into the bios menu fine. So I put everything back into the case and I'm back to where I started where lights will come on and the fans will spin, but no POST and no beep codes. I'm at a loss for what to do next and any ideas would be welcome!
