PC restarting mystery #2

p3ep90 · Nov 8, 2015

Hi

Few days ago i posted my problem about pc restarting on moderate to heavy load which can be found here : http://www.tomshardware.com/answers/id-2833138/restarting-mystery.html?xtor=EREC-8889
My system :
CPU - AMD FX-6300
Mobo - Gigabyte GA-970A-D3P M
RAM - Corsair Vengeance 4GB x 2
GPU - Sapphire radeon 7770 HD
PSU - Corsair VS550
HDD - WD Black 1TB
CPU cooler : Coolermaster hyper 212x

Since my CPu temps were pretty high i opted for the aftermarket cooler, which helped me alot in that area, my temps dropped about 5C idle and 20C on load. My PC ran fine for a day, but suddenly it restarted while i was playing a MMO (its not graphic intensive, my old phenom II would run it easily with HD 4890), i touched the CPU heatsink, which was cold but the northbridge heatsink was way too hot that i could not even keep my finger on it for more than 2-3 seconds.
Thinking that my northbridge might causing the restarts, i put a 80mm high flow fan to blow air across the northbridge. But it keeps restarting as soon as i run 2-3 games or at times even browser + 1 game or even torrent + browser. The northbridge is not getting too hot now though.

Any kind of help is appreciated, i am hitting a dead end :|

What can possibly be wrong? could it be my PSU?

Northbridge chipsets are generally hot to the touch. It's hard to tell what is causing the reboots. Have you checked windows logs to see if it is throwing a code. This usually helps me figuring out if it was a driver problem or hardware. For giggles try re-installing your graphics drivers to the latest version. I have had them corrupt on me before, and do funky stuff.

This article might help you with the logs

It could be. The entry level VS is not intended for gaming systems. Try testing different one, if possible.

boodaddy :

I already tried reading event logs it shows kernel id 41 error, which is power loss i think. But sometimes it has no signature in the log, like nothing happened.

boodaddy · Nov 8, 2015

Do you have Minidump enabled? Minidumps should be located in C:\Windows\Minidump. They can also be very useful.

boodaddy :

i did not had it enabled, i just did, i am trying to stress it right now but its not rebooting. I will update as soon as i can.

p3ep90 · Nov 10, 2015

boodaddy :

So it restarted again, with nothing running except Bittorrent., no minidump found, error was same, critical kernel 41. It was running for over 8 hours previously, northbridge was somewhat hot but not untouchable.

What program are you using to monitor temps?

Definitely sounds like PSU to me.

What are your CPU and GPU temps?

p3ep90 · Nov 10, 2015

tiny voices :

CPU 38C idle, 45C load
GPU 38C idle, 51C load

tiny voices · Nov 10, 2015

Those temps are plenty low. Sounds like that is not the issue.

boodaddy · Nov 10, 2015

I agree with tiny voices. It's sounding like a PSU getting ready to totally go out. Do you have another one you can test?

p3ep90 · Nov 10, 2015

boodaddy :

Sadly, no. I will have to buy new if i want to test it. Any suggestions what i might write to the company when i send my PSU since its in warranty atm? I cannot just say "my pc is restarting so please replace"

tiny voices · Nov 10, 2015

It is just not a good quality PSU. You don;t really want a replacement of it. You want to buy a new, proper quality PSU.

boodaddy · Nov 10, 2015

p3ep90 :

You have a couple options, but like tiny voices's said you will want to get a better PSU. If your low on cash, I totally understand doing what you got to do. You could take it to a local PC shop, and have them test the PSU to confirm (Shouldn't cost hardly anything) and use that as proof for RMA.

You can also go to a local store like best buy, and purchase one, and if it works without problems, you can also use that as RMA proof. Best Buy has a good return policy.

Actually telling them your computer keeps restarting is normal for a PSU going bad. Most of the time they never make it out of bios post before restarting. Tell them when the computer is under load it just restarts, and give them a rundown.

Your only other option is formatting and reinstalling windows to make sure something isn't corrupted. Your temps are good so the GPU/CPU isn't overheating. I wish I could help more, but at this point without another PSU for testing these are about your only options.

any suggestions for the new PSU?

boodaddy · Nov 11, 2015

Here are a couple great research posts for PSU's

http://www.tomshardware.com/answers/id-2110001/psu-suggestions.html

I guess everyone has there own favorite brand. I only use Rosewill psu's. Heck, I even have a Rosewill dedicated to running a PC R9-280x that I flashed with the Apple firmware to make it work on my mac pro lol. I love the brand. I would go with 850w to 1000w and emphasize more on the 1000w end, because you won't have to worry when you upgrade hardware in the future.

tiny voices · Nov 11, 2015

There are plenty of Rosewill PSUs that are junk. You need to be careful just recommending an entire brand.

boodaddy · Nov 11, 2015

tiny voices :

There are only about 8 PSU's that RoseWill makes from 850w-1000 from bronze to platinum . Any one of those are great imo. I had miners with triple GPU's mining bitcoin with them 24/7. Never had one failure. Like I said. To each is own.

tiny voices · Nov 11, 2015

Yes, the higher wattage ones are good, but they make plenty of 750w and lower poor quality units.

boodaddy · Nov 11, 2015

tiny voices :

I see your point. I should have clarified that if he went below my 850w-1000w recommendation to be careful.
@p3ep90 DON'T GO BELOW 850W-1000W :bounce:

tiny voices · Nov 11, 2015

He has no need for that much wattage. A good quality 500-600w unit is plenty for him.

boodaddy · Nov 11, 2015

No offence, but with the prices on PSU's now days. 500-600w would just be stupid. He is limiting himself doing that if he ever wants to upgrade. It's one less thing he has to buy when technology gets better, and the price difference is hardly noticeable between 600w & 1000w.

tiny voices · Nov 11, 2015

This is completely untrue. Show me a quality 650w unit that costs as much as an equal quality 1000w unit. You cannot.

Also, 650w is plenty for ANY single GPU out there. Even 750w is more than he needs.
