Now, I have a hunch that it is my motherboard, but I'm not 100%. I built my computer almost a year ago, and it's been working alright for my first build. Haven't run into too many problems that I haven't been able to solve easily until today.... I was on my pc, then I went to class, came back an hour later and my pc was off. Thought it was strange so I went to turn it back and and it started up, fans and led all work but there was no signal and no visible power to usb devices hooked up. It won't post, but if I recall correctly it doesn't always post for me normally. I did try running with no RAM and got the chain of long beeps, tried taking my graphics card out, unplugging the PSU, cycling the power, tried booting with my graphics card out and reseting the cmos. Nothing works, ide like to say that my MOBO is garbage because of the ports not working but then again it could be a PSU issue, and from what I've read it's highly unlikely that my cpu would fail before the other two. My MOBO is an MSi 760gma. Any thoughts on what could be the issue?
