I have a PC that I've been using for about 7 years, and despite doing some minor upgrades like adding more RAM and a new graphics card, it's still hanging in there for most games. However, yesterday it refused to boot—I'm getting no post signals, and the VGA light on the motherboard's debug panel is lit. I've tried swapping my graphics card, moving the RAM around, and resetting the CMOS, but nothing seems to work, so I'm suspecting my motherboard (a PCMATE B350M) is dead. I'm considering buying a used B450-F Carbon AC motherboard from eBay as a replacement. My main concern is whether I should also replace the PSU at the same time, since I'm worried a faulty PSU might have caused the motherboard failure in the first place. Any advice?

You might want to try using a different graphics card if you have one available, or testing it with the onboard graphics if your motherboard has that option. The fact that the VGA light is on could indicate an issue, but it doesn't necessarily mean the PSU is the problem. Just be careful—if the PSU is failing, it could potentially damage a new motherboard as well. It might be worth diagnosing the PSU first before making any purchases.
Honestly, if you're pretty sure it's the motherboard, just go ahead and get a new one. Just be cautious, though—if the PSU is indeed faulty, you don't want it frying your new board too! Maybe you could pick up a PSU tester or even just look for a new PSU while you’re at it, just in case.
What if the PSU ends up frying the new motherboard as well? That’s my biggest worry with this situation!
Yeah, I get your concern. It's a bit of a gamble if you don't know for sure what’s dead. Maybe consider testing the PSU with a multimeter to see if it’s functioning properly before committing to a new motherboard.
