So, several months ago I put together my own desktop PC. I set up a dual boot to Windows and Ubuntu.

Recently, without changing any settings or installing anything new, the wifi stopped working on windows (I use a wifi adapter). It said it was connected, Network settings showed that it was working and running trouble shooting had no results. My internet still works on any other device. I found that removing the adapter from the motherboard and plugging it back in was the only thing that fixed the problem. Reinstalling the wifi drivers did not help. I purchased a new Wifi adapter, but the problem persists.

More recently, I had a much more discouraging development. Sometimes, turning on the computer results in a boot loop: BIOS never starts. Instead, the monitor turns on as if it got a signal, then immediately turns off. This loops on it's own indefinitely until I hold down power, hard reset it, and try again. Sometimes it works, sometimes it doesn't.

I haven't tested much on the Ubuntu side. It appears that wifi works at least some of the time, but since I've had issues just getting to BIOS I'm not confident the issue is on the software side.

I've also noticed issues with some of the USB ports no longer working, but that seems to be off and on.

Finally, as of a few minutes ago, I booted to windows to discover that everything was running very slowly. Slow here is a relative word, but I have a Samsung 840 pro SSD and I'm used to applications running nigh instantly, and it was a solid 3 minutes before any of my applications would load.

Anyway, my question is this: Is it likely that my motherboard is failing? Either way, what steps can I take to try and pin down the problem and figure out what to do?
