CPU freezes PC randomly

[l3tr1xingame]

Hello
Recently when I changed my Pentium G630 for a Core i5 3340, my PC freezes randomly and after some minutes it restart. I have tested changing all other components for make me sure than the CPU was the problem and yes, it is.
Is there any way to fix it? Thanks.
I already made clear CMOS but nothing.

If you leave your computer on in just the bios does the computer eventually "cut off"?
How long does it take for the computer to "cut off?"

I disconnected the hard drives, disk drive and GPU. It's been on for an hou and hasn't cut off yet.. Temperatures of 49°C / 120°F.

When it cuts off is it a blue screen, does it just shut off and stay off, or does it restart?

Shows last screen before freeze and few minutes after restart. Now I'm using Live Ubuntu. I'll see if it freezes now. Then I'll connect the other components and see which one is faulty.

If a computer has a bad power supply it will run for a little bit, and shut off seemingly randomly, getting more frequent till the power supply actually dies, and then it won't start at all. You are not having high temperatures with your CPU, which the motherboard protections would cut off the computer to protect the CPU. In the process of dying as the power supply goes bad it can damage other components, motherboard, CPU, RAM, hard drive, and all that it's connected. This is why I have been leaning to one of the power supplies being bad. But if it has damaged other components buying a new one will not completely fix your problem. Cheap power supplies rearly last longer than 5 years of continuous use, and are very light weight when holding them. I notice this usually happens on older systems when upgrading components adding more strain to an old/weak power supply. There isn't much reason for your computer to shut off during installation except for a hardware problem.

Exactly. There is some kind of hardware problem if it shuts off during installation. Either the power supply, motherboard or one of the drives is faulty if that happens. I mean, just about anything CAN cause issues, but clearly those are the most common. Since both those power supplies were junk even when they were new, and you will need a good power supply no matter WHAT you end up doing, it's probably a good idea to buy a known good, reliable power supply unit.

Might fix the whole problem, and even if it doesn't, at least you a solid foundation to begin figuring out WHAT else it might be. Very hard to guess when you have zero clue about the PSUs you currently have.

I'm now installing Windows 10 x64 using i5 with one HDD connected and with two other RAMs different from the previous one.
The previous RAM is a FOX DDR3 4GB 1333MHz. Now I'm using a Kingstone and other unknown.
No failures so far.
I still have to connect my GTX 1050 Ti and see what happens once the OS is installed.

I have installed my GPU, other HDD, updates and drivers with no issues on clean install. I think it's fixed. Could have been a previous RAM problem.

Cool. Glad you got it sorted. Definitely could have been an issue with the memory. Memory AND motherboards can be VERY finicky sometimes.

If freezes come back, check the cpu socket pins of the motherboard, if not done yet.

would use memtest.org usb autoinstaller, boot from usb, to check if all is fine with the RAM now
