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.
 
Have you looked at temps? Have you tried applying new thermal compound to the CPU? Try looking in the bios and see if you can see what the idle temp is since the computer keep shutting off. Also, have you checked the power supply? A bad power supply could do this same thing.
 


Idle temps are 35-40°C. I tried two different Intel Stock coolers and nothing. I think the power supply is fine because never give me problems when I'm using it.
 


I will try it later.
And yes, the CPU is the problem, only haps when I use it.
 


The temp untill cut off was 48°C with a maximum of 60°C when was stressed using CPU-Z.
 
Ok, install CPU-Z, open it and hardware monitor at the same time then press print screen. Open MS paint and click on paste. Save and upload to imgur, and post the link here so we can see if something is out of place. Maybe voltages. Optionally, you can also, try putting the other CPU back in the machine and run something CPU intensive to see if it shuts off. CPU-Z has a small benchmarking tool that will put some stress on the CPU.
 


I'm using an HDD with Windows 10 installed using the i5 CPU.
G630 CPU is working fine in the same motherboard so I don't think there's any bent pins
 


My PC was pre-built and has come with ASUS H61M-K and the i5 CPU. This motherboard has one RAM slot fried so I changed my CPU and other components to my old PC with an Gigabyte H61M-S (Pentium G630).
Now old GB's Mobo isn't working so I'm taking back components to ASUS's mobo but i5 isn't working well.
 
Are you using the same power supply? Bad power supplies kill components. What is the make and model of the power supply? We can determine what protections or lack of protections are on the power supply. If it's a bad power supply, which it sounds like, you will just keep killing components.
 


Sentey 450w (using now) is old and came with the Pentium G630 PC. Eurocase 500w come with Core i5 PC.
Core i5 was using Eurocase PSU before Mobo stopped working.
 
Do you have model numbers for those PSUs? I found the website for http://www.sentey.com, and nothing on the other one. I did post a note in the power supply discussion thread to see if I can get any input from there on these brands. I looked for the brands you are using on the tier list and couldn't find them. http://www.tomshardware.com/forum/id-2547993/psu-tier-list.html Not sure where you are located, and what your selection of power supplies are, but it would be worth buying at least a bronze efficiency power supply from a reputable brand.
 
If you changed platforms/generations of CPU, including motherboard, you cannot realistically expect to continue to use your previous Windows installation as is. No offense Helpstar, but simply deleting "processors" in device manager isn't going to be terribly helpful in most cases unless you've only changed to a different CPU that is part of the same gen.

Differences in chipset, including CPU, motherboard and storage controller drivers, are usually not well transitioned to a new and different hardware configuration.

I would highly recommend that you start by doing a COMPLETE, FULL and CLEAN installation of Windows to eliminate any possibility that previous drivers, registry settings or resource allocations are not to blame. After, when you have finalized the reinstallation of the most updated driver versions and made sure that your motherboard bios is fully up to date on the latest revision, if there are still problems, THAT is when you should start looking at other issues.

Saying "this only happens when I use the CPU" makes absolutely ZERO sense, because you are ALWAYS using the CPU, every millisecond the system is on. The problem COULD be related to the CPU, but at this point I think it's a stretch to simply assume that it is without taking the correct steps to eliminate other likely and probable problems first.

As far as the power supplies are concerned, Sentey has VERY few units that they've ever sold that were not pretty bad and most were terrible. Eurocase is also not a well known trusted brand and is likely to be low quality, although I see NO reviews ANYWHERE of any Eurocase power supply so I can't tell you that it's likely to be your problem unless you are running a discrete graphics card that requires supplemental power or are overclocking. Since neither of those seems to be the case, it's not AS likely, but still IS likely to be part of the problem. I would resolve other issues before focusing on this however, unless you have or can borrow a known good high quality unit temporarily to further eliminate these power supplies being to blame. While it's clear they are not good, I do not think this is the primary problem, yet.


Start with a clean installation of Windows 10, unless the problem is so bad that you are unable to perform a clean install. If THAT is the case, THEN it is likely you have a CPU, motherboard or power supply issue.

Both PSU come with the PCs. Sentey's one should be better.


I don't think it works because I'm using an HDD with Windows 10 that was installed using Core i5, but I'll try anyway. Also I'll try using Ubuntu, for see if the same thing happs.
Thank you for responding.
 
Yes, using a Linux or Ubuntu distro will tell you much about whether the problem is software or hardware. It's often a good idea to do this when you need to eliminate the possibility of it being a Windows issue versus failing hardware. +1.

Yes, the Sentey unit PROBABLY is better, at least when it was new, but there's no guarantee of that because Sentey has some pretty terrible units as well as one or two that are not too bad. That could go either way and I would be disinclined to make that assumption without absolutely knowing the exact model number of the Sentey unit. Knowing how old it is could be a factor as well. Just because it was good when it was new, three or four years ago, doesn't mean it's still "good" now. That actually goes for both those power supplies.

Also, just because that OS installation was done WITH the correct CPU and motherboard doesn't mean it was done correctly. So if you got it used or in some kind of used "refreshed" state, as a preowned prebuilt system, it would still be highly advisable to do a clean install. Usually, they come all screwed up or filled with error causing bloatware. I'd do a clean install no matter what. At least that way you KNOW that it isn't the problem and can move forward.
 


I couldn't install Windows becauses freezes!. What can I do now?
 
update the BIOS of your ASUS motherboard within BIOS using ezflash
https://www.asus.com/Motherboards/H61MK/HelpDesk_BIOS/

Also have a look at the temperature of CPU in BIOS. Wait about 10minutes, to get the max . temp.

Did you check the Pins yet?

use memtest.org usb autoinstaller, boot from usb
 
You might also try disconnecting ALL the hard drives except the one you are planning to install Windows on, and if possible, if it does the same thing, try a different drive. Could just be a faulty drive, or could be as helpstar indicated you need to update the bios but I'd be a little bit leery of updating the bios on any system that doesn't have Flashback or a similar method that doesn't require the system to be running in order to update if it's freezing up. Freezing during bios update could brick the motherboard.

Chances are good that if you bought this system used, and you've had this problem from the start, that you simply have a bad motherboard or another component. Pretty common though used channels. Try a different drive to install to first though.
 
Guys he told us some critical information here:
My PC was pre-built and has come with ASUS H61M-K and the i5 CPU. This motherboard has one RAM slot fried so I changed my CPU and other components to my old PC with an Gigabyte H61M-S (Pentium G630).
Now old GB's Mobo isn't working so I'm taking back components to ASUS's mobo but i5 isn't working well.
I think at the very least he needs a known good working power supply.

Edit: He installed HWmonitor and watched the monitor until the computer "cut off" during operation, and the temp was:
The temp untill cut off was 48°C with a maximum of 60°C when was stressed using CPU-Z.

2nd Edit: Some choices when looking into a new power supply. Look for 80+Bronze as a minimum starting point. I know good power supply can be costly, but it's a good investment for the lifetime of your computer.
You can change the country in the top right corner. SeaSonic or SuperFlower tend to be good power supplies.

I tested the CPU with two HDDs with Windows 10 installed and the same thing happened. One used Pentium G630 and the other Intel i5-3340. I use mine which is the i5 one and come from my other PC.

Both PCs are new and used for 2 (G630) and 1 (i5-3340) years. Also both have latest BIOS.
