Well since you've fixed CPU overheating issue and power supply has good voltages ,download HWMONITOR | Softwares | CPUID and check graphics card temperature & all temperatures overall.Too hot hard drive or graphics card cause restars.

That power supply is old but it doesn't mean that it is the problem.My power supply is almost 8 years old man.Never had a trouble;it survived fried motherboard,a thousand power outages,..

Yes,power supply might be the issue.If you can lend someones power supply to check is it the issue,just to be sure.

Also,check all your hardware connections.

I've applied the thermal paste and the CPU temperature doesn't go above 40ēC now, but computer still restarting randomly. Most likely PSU, right? Any way to know if that's it or no? I don't have another PSU or anyone with desktop computers to lend me a PSU... :\
I just thought of a problem I had when I installed my Corsair PSU. The 24 pin cable from the PSU to the Motherboard was very hard to secure. I did not hear a click when I connected the PSU. If you are not hearing a definite CLICK when you connect the 24 pin cable, it is not connected.

I have that also. Let us know the Speccy and Bios temp.
Hello!

I've reused my PSU and RAM from my brother's old computer, don't know the exact date of when the PSU was bought, but I'm nearly sure it's 5+ years. On the BIOS the temperature doesn't go above 40ēC since yesterday, when I applied new thermal paste. And I can't check on speccy now because the restarts don't let me.

I can buy a new PSU, but I really want to make sure that it is the PSU that is failing, since I am saving for an SSD and buying a new PSU when it still won't work would be absurd.

Thanks for your help!
You are in Portugal, I am not sure what you can buy online there. In the USA I purchased a PSU and it did not correct my problem so I was able to return it. If that is possible where you live, that would be an option. I returned mine from Newegg.com with the explanation taht it did not work. If you can purchase from them where you are, that would be a solution to your problem.
Don't think there is any store that will take the PSU back and give the money, to be honest. Also, the PSU fan is spinning, could it mean that the PSU isn't the problem, or it can still be?

I can't run that if my computer keeps restarting... :\

All my hardware connection seem to be right, and my friends that have desktops have PSUs that are not compatible with my other stuff...

The 24 pin cable is connected correctly.

If the fan is running, that does not mean the PSU is good. It could still run no matter what. == If your temps are good and you have checked several other things also, I think the only thing left is the PSU being bad.

Whatever, I'll risk it and buy the PSU the upcoming week, really hope that's the issue. I'll need a new PSU if I upgrade anyway.

Thanks for your help guys, I'll reply again if the new PSU does not solve the problem.
