I'm new to building PCs and currently have a prebuilt system with only 8GB of DDR3 RAM. I'm planning to upgrade to 16GB by buying a used 8GB stick, but I'm worried that the RAM stick might be faulty. If that happens, could it potentially damage my hardware or software? Am I overthinking this? If the stick turns out to be faulty, I should just be able to remove it and everything will be fine, right? Also, what software do you recommend for testing RAM? Thanks!

I think you're overthinking this! A faulty RAM stick won’t destroy your PC. It can cause a BSOD or just hang during boot-up. Once you take it out, your PC should function normally again.
If the RAM stick you buy is faulty, your PC simply won't boot up until you remove it. It won't destroy your hardware, but it could cause errors and instability while it's installed. You're more likely to run into issues like the Blue Screen of Death (BSOD) or just a failure to start. Once you take out the bad RAM, everything should return to normal.
Faulty RAM usually means it won't work at all. I recommend using a program called Memtest86 to test it. You can install it on a USB drive and boot from there. Just make sure you have empty slots available in your PC before you buy the new stick.
If memory errors occur, it can lead to data corruption or instability, so I'd say keep backups just in case. The worst that could happen is software side issues, like needing to reinstall Windows. But the stick itself won't damage your hardware.
Yes, faulty RAM can corrupt your files. It might not damage the hardware itself, but it can definitely mess up your data and your operating system.
