    computer keeps restarting

    Locked

    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
        Cheers

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

        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.

        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

      Have you checked the Event log?

      by overwrked1 ·

      In reply to computer keeps restarting

      Are there any indications something caused a bug check? If not then check the power supply, big boards (speed, graphics) require big power when running and though you have a 500 watt unit a power fail from the power supply will cause a reboot as well. One last thing, are you using a lot of flash in the games with the ATI card? I had an issue with the dual head cards rebooting with a bug check from flash apps in XP. Good luck!

      In reply to computer keeps restarting

      well it cant be an error with soft ware coz i reinstalled windows so it cant be a error with windows or any drivers coz i updated my graphics drivers aswell i have not checked my power supply but i doubt verry much it could be that coz my other pc is running a 560 ti with a 450 wat and playes exactly the same games as me and when ever i play dark sider on my amd card my card gets hot the when i close the game it will stay 80 degrees and my gpu core will get to 99% it only happens with that game though i dont think that is normal though why is it doing this i dont really want to use my 560 coz its not as powerfull as this card and besides i had problems with it in my amd computer coz my board is amd and when i got the intel pc it worked fine in that one coz intel and nvidia mix well together thats why i got a amd card for my pc but now there is restarts and everything i dont know exactly where the problem may lie as you guys know that a pc restarting could be many problems just have to find the right one.

        In reply to One game or all?

        At my last company we use to use games to help stress test the hardware. Some games we could get it to crash with regularity, others seemed bulletprof and rarely crashed.

        The games in which we found that crashed our machines we could then start to compare how each came called/used the CPU and GPU.

        So that is where I was going with my question. 🙂 If it crashes witth just one or a couple of games then you have to start to look at what is it doing leading up to the crash.

        We found a game that would crash if you just let it sit for about 45 minutes (later we found it to be due to a memory leak and the game publisher had issued a patch to fix it).

        World of Warcraft, back when they first started out, was a great testing tool for us. There were a lot of info on their forum, other forums/blogs to aid with the troubleshooting of the hardware.

        Then we move on and troubleshoot something else. But from my chair here, and the facts you have described, this is the most glaring suspect.

        A friend of mine gave me a laptop with similar symptoms to work on. He would be using Microsoft Word, or surfing the web and it would randomly restart. After I gutted it, I found that most of the thermal paste had oozed out from in-between the CPU and heat-sink; probably applied incorrectly at the factory. I removed the old stuff with acetone, dried the contact points, then applied a new layer of paste. He has not had a problem since.

      No i do not have a cat and i did take out all the dust already i took off my cpu heat sink and cleaned it i cleand inside my pc and still what could be the problem could it be voltage maby or maby some component on the motherboard is causing it too restart ? i dont really know i aam a computer tech i did everything to solve the problem but its not working so it leaves me with only one option since i really need my pc to be fixed and i use it a hell of alot if i fail to fix the problem i have to buy a new motherboard coz that could verry well be the problem i dont think its my psu and i dont think its my ram coz i used mem 86 to test it and all came back normal well i do have a problem with my one ram slot when ever i put a ram stick in there it will beep like about 3 times i know thats a ram error this all happend when i got my new empty case coz i had gotten a bigger graphics card so i had to get a bigger case and ever since i put my motherboard in my new case with my new card i have been having all these problems and another mother board like mine is expensive i dont really wana spend so much money to buy a new motherboard if its not that and besides its hard to find amd motherboards in a normal shop in most cases you must order them but any way i have left my pc on hole night doing nothing just on idl and it hasnt restarted since i have cleaned it out im gonna leave it on again this time using a graphics stress test and see if it shuts down or something.

      Disconnect

      In reply to computer keeps restarting

      Disconect for test all of your not needed hardware (DVD, external USB’s, FDD (if you have), second HDD, speakers, etc) and try again with the same game. If it is working without crashes then buy new psu at least 750w. If it is not working try to get some extra cooling (reear fans etc.) and exam what is the air-flow of the computer case.

        verry good air flow i have one rear fan a huge 120 mm fan on top and another huge 120 mm fan in the front the box is verry big and has alota space you can check out the box at this link

        and tell me what you think of it i paid about R 2 000 for this empty case and it not small at all lots of air flow check it out

      Shane which way do you have the fans blowing?

      by oh smeg ·

      In reply to computer keeps restarting

      The Back ones should be blowing air out the back of the case the same goes if there is a fan in the top at the rear and the one/s in the front should be blowing air into the case.

      That way you get good air flow through the case with no Hot Spots. Of course that means you don’t have anything blocking the air flow at the back or top of the case like in a hole on a desk that just fits the case with 5 solid sides where the air has to come out the front and the hot air gets sucked back in.
