Hello. My PC has the following specifications:

Mother board: Asus M5A78l-M LE
Processor: AMD FX 6300 Six Cores 3500 MHz
Graphic card: Nvidia GeForce 750
RAM: 8 GB
PSU: I think it is this: 480W be quiet! AC-WildRabbit Series

Well, I bought my PC two years ago in Amazon. Herew is the link (many things are in Spanish, as I'm from Spain). https://www.amazon.es/Ankermann-PC-Baratilyo-FX-6300-Turbo-4260219658690/dp/B00BAQM72M

As you can see, the motherboard is different. This is because my PC stopped working in August after having worked perfectly for two years. I had to take the PC to repair, and they said that the motherboard was broken, so they changed it.

Now the PC starts fine, but when I play videogames it randomly freezes (and I have to turn the PC off and then on again) or shuts down (and then it reboots). Sometimes the same happens when I watch videos. This didn't happen before changing the motherboard.

Yesterday I took the PC again to repair, and they said that probably it was due to dust. And they cleaned my graphic card ventilator (I think, I don't know a lot about PC parts) because it had a lot of dust. However, this hasn't solved the problem. Today I've been able to play for two hours with Batman: Arkham Origins, but at the end the PC froze. Then I played the last Sherlock Holmes game and after 15 minutes the PC froze again. Next I will try playing The Witcher III with full graphics, as my PC ran it perfectly for hours. without a problem. However, I don't think there will be any differences.

I've red on the Internet that the problem might be the PSU or the temperatures. I've installed HWMonitor to check the temperatures and all that, but I really don't know what to check.

So this is my situation. Do you know what is happening with my PC? Any solutions? Thank you.
 
Solution
That would be my first thought - need a good 400 with 20 AMPs on the 12 for a 750 GPU and your PSU has the 12 volt split among 4 rails so not optimal

I don't have any idea what that means, but I'll keep this in mind. Thanks.

So any other possible ideas about my problem?

OK, thank you. For now I'll wait until I've tried some other games. Next Friday I'll take the PC again to repair, and I'll ask about the PSU, since I don't know very much about the internal parts of the PC.
