I've got a two-year-old PC that's been running fine until tonight when it suddenly crashed while I was just browsing the internet. After a restart, it crashed again about 45 minutes later and now it won't even post. I've tried swapping out the power supply with no improvement, and I checked all the connections, so it seems like there might be a hardware failure going on here. Should I start by replacing the motherboard?

I would recommend checking if your motherboard has any diagnostic features. Some boards have lights or beep codes that indicate what's happening. If yours doesn’t light up at all, you might indeed be looking at a motherboard issue.
First off, what motherboard do you have? If your board has built-in diagnostic lights, those can be super helpful in figuring out what’s going wrong. If the board isn't lighting up at all, it could really indicate a bigger issue.
