Computer restarting problem.

[PappSzi96]

Mobo : MSI B75A-G43
RAM: Kingston HyperX KHX1600C10D3/4G * 2
CPU: I5-3570
GPU: Sapphire Radeon Rx 470 4Gb
PSU: Chieftec CTG-500-80P

So when i use my pc with the CPU's integrated graphics, and the video card not plugged the config work well.

When i connect the vga and start to use that my computer restart randomly.

The VGA with my psu was tested in my brother's pc. The memories was tested with memtest86+(0 errors), the cpu without the vga was tested with furmark's cpu burner.

So have you got any solution for this ?

Sry for my English.

The only way you can 'test' a PSU in another system is if it's the exact same setup. If your brothers PC has a different CPU/Motherboard/RAM etc, it's no guarantee it'll work on yours as there's too many potential variables.

You've checked memtest and CPU burner, so it sounds like your system is solid to begin with, but you're describing a pretty common situation where the PSU is not capable of adequately powering your setup.

I've never seen a good review of a Chieftec PSU (there are very few reliable reviews to begin with!), so I'd be pretty confident that it is the route cause.

I'd ensure you clear your CMOS first of all, and then try with the GPU once more - but I wouldn't hold my breath.

A new (quality) PSU appears to be in order.

 

[PappSzi96]

This is a new psu. I forgot to say that. PSU, Motherboard, VGA are new ones.

 

[Barty1884]

I don't mean a new PSU as in fresh out of the box, I mean a replacement PSU.

You're describing the common symptoms of an underpowered (or mislabled) PSU. It's not of sufficient quality to run your system safely.

Video card System Requirement
500 Watt Power Supply (Suggestion)

Chieftec CTG-500-80P

Review says, "PSU is definitely an entry level product and its not meant to be put into powerful builds.".
To me, it looks as if it can put out 400 watts.

 

[Barty1884]

Looks like it can, from information Chieftec supplied.

That review is very basic & doesn't really address much - I've also never heard of the reviewer, so I've no idea how well they are considered.

It's definitely built to a budget - and not really intended for any decent GPU load from it. A 2 year warranty is very low, and all chinese caps isn't exactly great.

Entry level PSUs are good for basic office rigs, or something up to maybe a 750/750TI, beyond that, they're rarely a good idea.

 

[PappSzi96]

Okey i tried it now with my brother's fsp hexa+500 psu, and the result is the same. I tried it with an other CPU too. Same.

 

[PappSzi96]

So not the PSU is the problem. I reseted my bios fully, tried same. I tried it with only 1 single ram modul. Same. I tried it with a g2030 CPU. Same..So i havent got more idea...

 

[Barty1884]

FSP's Hexa is a relatively solid PSU, so that definitely is interesting....

Both desktops (yours and your brothers) have the latest BIOS installed?

 

[PappSzi96]

Y, latest bios. And this motherboard can hold much stronger configs...

 

[Barty1884]

I never said it couldn't? I'm trying to determine all the factors in play here.

You're using the entire 8pin connector? Assuming it's a Sapphire Nitro card. Essentially, confirming you're populating all PCIe power connectors required by the card?

 

[PappSzi96]

Nope it's not a Nitro. There are two sapphire rx 470. A nitro+ and a Sapphire radeon 470. It needs only one 6-pin connector.

Here is the product link : http://www.sapphiretech.com/productdetial.asp?pid=0582294D-5A90-4EF0-B5E1-5EDC1C3ACBE1&lang=eng

And yes, 6 pin connected, on-board 8 pin connected.

 

[Barty1884]

Wait, you're able to boot to the desktop & use the system, with random reboots occurring?

Or does the system not actually boot at all, getting stuck in a reboot loop?

 

[charliewhiskey]

Could be hot CPU or GPU. What kind of thermal paste did you use on the CPU? Or have you not checked it? Try to get some CPU temps before the system restarts.

 

[PappSzi96]

I use be quiet DC1. My case is a CM n200 with 3 fans. And a Zero Infinity Shiva CPU cooler. My temperatures fine.

I can boot to desktop fine, i can use my pc fine, but when i for example start a valley benchmark, or a cs:go it restarts. And sometimes with no reason it restarts. I thought first time it will be the psu, but with another psu the results was the same.

 

[Barty1884]

Ah, sorry about that. I misunderstood.

Do you have the latest GPU driver installed? And have you removed all prior GPU driver versions?

You can use DDU to achieve this:

Also ensure all chipset drivers etc from your motherboard manufacturer are up to date.

You also want to ensure your temps are under control (CPU & GPU especially). I use HWMonitor to monitor.

 

[PappSzi96]

I installed a new windows today morning. I installed the latest gpu driver tried the valley bench, restart.
I installed then all mobo drivers, and then valley. Restart.

I replaced my windows with a new Ubuntu 16.04.1 LTS, installed my gpu driver, and the valley. I ran valley 2-3 times, and no problem no restarts. !

The only problem is that, when my bro tried this vga in his PC he used windows. So anyway i havent got idea for windows. With ubuntu it's fine.

 

[Barty1884]

Is your version of Windows activated & genuine? How about your brothers version? It's a long shot, as I can;t image why that would present an issue of this nature, but non-genuine Windows can do some funny things.

 

[PappSzi96]

non-genuine my and my brother's too...After 1 hour stressing in linux it restarted here too...without any log or something.

 

[charliewhiskey]

Wild guesses are now going to be implemented. Who installed the MB in the case? Did you use the correct hardware to do this? I get the feeling that we are dealing with a floating short somehwhere. If we eliminate software and hardware driver issues, a short, dirty or loose connection is next. Carefully start the computer with the cover open and do a wiggle test on the connections. Gently and WITHOUT getting electrocuted, wiggle all the wires one at a time. It the system restarts, you might have found the issue. Check the wiring including the power wire going to the wall outlet. Cycle the circuit breaker that the system is attached.

 

[Barty1884]

Ok, standard disclaimer that you should activate your Windows install by legally acquiring a genuine license.

So near immediate on Windows and after an hour on Linux.....on your system?

Have you tried on your brothers for an extended period of time? You had said it was running fine, but was that for 5mins? Or an hour+?
