Question I have some grinding noises and computer resets

Recently I've had some restart problems while playing a game (rallysimfans' Richard Burns Rally; I should try others.) First, I used to record some gameplays of it with Bandicam at 1280x720 resolution in fullscreen mode without problems, but since some months ago my PC would restart immediately (no BSODs nor nothing) unless I set the game to run on windowed mode. Then I had a restart while recording it at 800x600 in fullscreen mode, which also used to work, and it's the way I normally play the game. This week, I've had restarts while playing (not recording) it in that latter configuration, which never happened before. I think it only happened at stage-ends, or while switching back to the menu.

Maybe these problems are related with the noises I'm having: I think they come from the PSU fan. The only kind of noise I've had the past few years was happening only after turning the PC on; a quite loud and "constant" noise that would last a few minutes (usually <5) and would never come back for the whole day. I'm pretty sure it always happened only on "cold" days (like, >0 °C and <15 °C).

But now, there's some different noises at startup. As you can listen, specially from 0:20 onwards, those sounds aren't loud nor constant. They started happening about a week or two (don't remember) before I started having the restart problems this week, and these days were quite hot (>30 °C). The first time it happened, it lasted for the whole day; but the next days it would eventually stop and never come back. Maybe that first day was rather cold? Because today it's neither cold nor hot, and it's been already more than an hour since I turned the PC on, and those noises are still there; sometimes they stop for a few seconds, only to come back latter.
 
The best place to start would be a complete list of your specs, including the exact power supply.

I don't know if this is enough, or even right:

RAM: 8 GB total; two sticks of 4 GB each
Graphics: Intel HD Graphics 4400

Here's a photo of the PSU. Some translations: Entrada = Input; Potencia = Power; Salida = Output.

By the way, about half an hour ago I read this comment and tried to turn it off and on a couple of times, but the noise kept going. As of right now, it seems that it finally stopped completely after ~two hours. But for sure there's something wrong in there, and that noise will be back tomorrow when turning the PC on.

Also: if I listen closely when those noises happen, the PSU's fan (or whatever) changes its speed. Right now the noise is gone, and I can listen the fan rotates at a steady speed.

Sounds like a failing fan on the PSU that's causing it to overheat. Rolling up a magazine into a tube and putting your ear on one end with the other inside your PC should help verify this. You can also gently stop the fan with a wooden stick or something when the noise is happening and see if the noise stops.

Even without a GPU, this PSU a very low-quality unit that is also now likely very old. If it's a fan, the PSU should be replaced. If you do replace the fan, keep in mind any future upgrades you might make.
 
Any basic Corsair CV/EVGA BR would work for what is an office PC.

It's been an odyssey! I've bought a Corsair CV450 80 PLUS Bronze. It turned out the PSU was way bigger than I thought, and it didn't fit in the case. So I grabbed a very old one, went to the technician, and told him to change the components from one case to the other. Finally, I have the PSU installed and everything working nice so far. So I have some questions I want to confirm:

– Anything to do or worry about after using that faulty PSU? What about those restarts? Could they have done any sort of damage? (So far everything works, as I said.)

– Anything to do or worry about after installing that new PSU?

– This old case has some sort of rack in which the PSU is held, and one part of it covers the PSU fan; not so much of it; is that a problem?

- I have a second HDD that I connected myself, but as I don't have clips to hold it nicely in its designated place like the main one, right now it's lying in a metallic thingie, face up (with the back circuits kinda touching that metal.) Is that a problem?

– This turned into an odyssey when I discovered, the next day after posting this, that my phone won't charge at all; so I was left without PC and phone! Note that I was also having some problems with wireless internet adapters sometimes dropping speed and eventually disconnecting from the network, so I was using the phone to share Wi-Fi to the PC via the USB cable. Initially, it didn't matter if the phone was on or off; the screen would show that the phone was charging, but it charged from 4% to 12% over the course of 8 hours (as I was sleeping.) Eventually, I guess it stopped charging completely, the battery fully drained, and now the phone won't turn on at all. The phone and the battery were working fine before I realized that it won't charge properly; I tried different chargers and places, but it doesn't work. Could the PSU have damaged the phone?

Many thanks in advance!
