computer keeps restarting

By shane s ·
Hi guys i am a computer tech and i need a littile help my pc keeps restarting when ever i am like half and hour in the game or more but it just randomly restarts.

pc specs are

cpu-AMD phenom 2 x6 2.8GHZ 1055t
ram- 6 gig DDR3 1333 MHZ
Graphics card-amd readeon 6870 256 bit DDR5
power supply- 550 wat
HDD- 1TB
i have 3 verry big fans in my pc besides the ones on the powersupply cpu and graphics card

i dont know if its a over heating problem or if my cpu is overheating cause yesterday i opend up my pc i took off my cpu fan and cleaned the dust off and off the heat sink my cpu does seem to be out of thermal past but i dont think that could be such a major problem

my graphics card on idl runs 40 degrees

I have tried testing my graphics card using furmark and 3d mark 11 my pc didn't restart it only restarts when i play games i didn't overclock my graphics card it bran new only one month old and my graphics card is more then enough to run those games and yes i have unticked automaticaly restart on system failure so that i would get a blue screen next time it restarted and i didn't it just restarted with out any error i dont know what the problem is and i need help coz i dont wana be buying parts that arnt really needed.

So in the BIOS

by OH Smeg In reply to computer keeps restarting

What Temp is it set to restart the system for the CPU?

Also if you removed the Heat Sink off the CPU you need to replace the Thermal Grease between it and the CPU. That stuff is very easily contaminated and is there to improve Heat Transfer between the CPU and Heat Sink. Doesn't matter how long it's been there provided that the Heat Sink hasn't been disturbed but the moment you disturb the Heat Sink you need to replace the Thermal Grease.

HI i have set the bios to defults so the temp isnt set for the pc to shut down at a temp oh and i dont have any thermal past left all gone but im gonna buy more and i know its importent its just that i didn,t have thermal past to put on and i dont think it is my powersupply eather if it was my pc would keep restarting.

i forgot to mention that when im playing a graphics intensive game y graphics card will get up to 70 degrees i dont know if thats normal just to make it clear i have played and still playing all the latest games and more to come with out any lagging and i put everything on ultra its just that when im in a game for about half an hour or more my pc restarts with out a error i play bf3 on max and sleeping dogs on max and when i try to start skyrim 5 i cant start the game on ultrra other wise my screen will just flash and switch off but the moment i put everything on low it works and i dont know why its doing this now because i used to play that game now it doesnt work any more please help i dont wana buy a new graphics card these things are expensive remember my graphics card is only one month old.

Hi Shane,
It sound like your pc has a thermal issue. Whenever you run a graphics extensive application like games, your GPU and CPU temp increase abruptly. Even you provide external powerful blower fan into your pc, it can't help you much. As a suggestion, you can try liquid cooled fan.
the website will give you an idea http://koolance.com/cooling101-introduction

RE:- HI i have set the bios to defults so the temp isnt set for the pc to shut down at a temp

That's incorrect on any M'Board I have ever seen by default the Restart Temp of the CPU is generally around 65C which is way too low. You need to reset this to 80C or higher depending on what your M'Board BIOS actually supports. When you play Graphic Intensive Games both the CPU and GPU run considerably hotter than they do otherwise with all the extra Processing involved so you need to make sure that the restart temp of the system is high enough so as it doesn't restart.

While that was probably your initial problem with no Thermal Paste between the CPU and Heat Sink there will now not be the correct Heat Transfer between the CPU and Heatsink so the CPU will run much hotter. That Heat Temp is to stop the CPU from burning out/frying so as a protection measure by default it's set way too low.

ok thanx for your comment i will try buying a liquid cooling system but do you know how much it will cost to buy a decent one and i dont have any ep in installing a liquid cooling system. but as for my graphics card getting up to 79 degrees i find that verry strange and i dont know if its normal i had a nvidia geforce gtx 560 ti before and the temp was around 35 on idl and when i pl;ayed a graphics intensive game it would go up to 45 to 55 degrees so i really dont know why this one is getting so hot please any one if you got advise for me i could use it right now.

It's normal and you don't need any form of Liquid Cooling.

Technically it's better but it's also much more expensive and most times unnecessary or worse still kills the M'Board if the system leaks.

If you want to keep it down around the 55C mark you'll need liquid cooling but for real people 85C is not overly hot.

Are you sure coz this is the first card that has gotten so hot it says maximum temp 99 degrees if you say its normal then its fine but the card only has one fan on it maby if i get another gpu cooler like maby a twin frozer coller for the gpu will that help coz 79 degreess really worrys me alot coz i mean my gpu is still new and i really dont wana have to buy another one so soon. besides being a network tech i am also a hard core gamer and need my pc to be working perfectly.

That's fine the ATI Video Cards are tough

by OH Smeg In reply to computer keeps restarting

Unlike some nVidia cards which came out with a design fault and cooked themselves ATI Design a lot more Thermal control into their chips.

While a Bigger Heat Sink on the GPU will certainly not hurt just doubling the number of fans will not make it run appreciably cooler you need a bigger heat sink to spread the heat out. But that type of card runs quite happily without problems in a lot of computers and gets that hot without problems.

thanx so much that takes alota thought off me i always liked amd i used to be with intel then i changed completly to amd i just saw a major diffirence in perfomance and in graphics wise the graphics just has more detail and it just looks better the only thing what amd doesnt have physics but one thing i have notised is that they do have alota other technology that nvidia doesnt have and that makes up for physics i mean my 560 was good but in performance i think this card passes it in alota ways for one i think in graphics and in core clock speeds and so on.

I agree

Out of curiosity, do you have a cat (no jokes about satisfaction here :-)? Cat dander and underlying fur are very fine and aren't usually visible to the naked eye. But a good blowout with a can of compressed air may very well make your eyes water and your nose itch
