> ...was getting flaky powering back on when turned off, which I assumed was the motherboard. This is my PC right now. Sometimes it does a boot loop, where it can get to BIOS but not GRUB and I'm not sure why, as there are no error messages. Pulling the plug and plugging it back in helps. I'm not sure whether it's the motherboard, or maybe a disk not wanting to read data or something. Guess I'll have to wait and see, eventually swapping out parts one by one once it fails entirely.
