Help: Possible Hardware Failure

[Spongebob]

You can download some free software that will show you temperatures of components on your motherboard if the pc isn't too old.

Any recommendations?

It's been a while since I used one myself.  I'm typically using my work laptop and it gets replaced every three years, so I don't much need it anymore.  But here is a website with some recommendations for you:  https://www.softwaretestinghelp.com/top-...p-monitor/

I saw that some people were talking about cloning your hard drive. That would only be necessary if you plan to boot from the new drive or replace your internal hard drive. If all you want to use it for is backup, then file backup/copying is a better solution, such as those I recommended. A hard drive making noise isn't all that uncommon, but it could be telling you its about to fail; there's a lot of wiggle room on that. You can replace it and if you do that you can clone your existing drive and load it to the new one. I would suggest a solid state hard drive; no moving parts. But you need to check your PC specs and make sure your motherboard is designed to handle it; not all of them are and there are several different models/designs so you have to pay attention to the details.

I'm curious why you think your graphics card needs more power. The power requirement should be on the box and you can check your power supply to determine if it is adequate. What you're looking for is the wattage available.
