Solve : Computer shutting down when playing a game?

Answer»

My computer is shutting down by its self when I start up a game.  I can play it for about 5 mins or so then the computer shuts down.  I know it is not a over heating issue cause I can have the computer idle for hours.

My Computer parts
Motherboard: XFX nForce 780i
Ram: 4g DDR2
Processor: 2.5 Intel Quad Q9300
Video Card: Nvidia 8800 GS (newest updated drivers)
Hard Drive: Maxtor 500g
OS: Vista Home 64bit (have all updates)
Browser: IE

I run the game Fable

I have seen the games say that I am only running 512mb to run the game but it only REQUIRES 256

Game Requirements
XP
256
1.4GHz
3gb
64mb shader capable - 3d card

Any suggestions? Quote

there is a huge difference in temperature between running idle and running under load. download coretemp found here and download prime95 found here. coretemp will let you know your CPU temp and prime 95 will place your CPU under a huge load. i dont know how well the 64bit version of prime 95 handles, i have never used it, so you may need to do some reading to find out how to test all 4 of your cores at the same time. please post back with your idle temps and with your load temps.Well I don't know if it good or bad. The temp would get up to 125c on all 4 cpu's, then after awhile of high activity the computer shut off.  I checked all fans they are all working.  I have 1 cpu fan on the processor one next to it blowing on it.  then I have 2 other extra fans to blow air through the case.  I have a 800W power supply. So in all with the fans I have is about 8 fans blowing in the case. (video card, power supply, 2 CPU fans, and 2 extra fans)  I went in to BIOS to see the percentage of the fan speed they are at 100%.  What is the next step?  Quote

If this were true they would have melted by now...
Please re-read Homer's Post and follow the steps and links outlined... Quote

  are you sure?? as patio has stated that temperature is extremely high. is your CPU overclocked?

please give us more info...

it sounds like you have six. how many fans do you have and are they all placed correctly? do they promote linear airflow or do they impede it?
At idle and they stay consistant.
TJ. Max 105 c
Core #0  77
Core #1  77
Core #2  73
Core #3  73

When I ran Prime95 all CPU's fluctuated between 73 c to 125 c.

I have not over clocked my CPu unless it was preset that way.  I will check to see if it is.

Fan 1: I have a fan in the front bottom of my computer that flows to the front out
Fan 2: In Back that Flows out from back.
Fan 3: This fan sits at the bottom of the CPU pushing air upwards

CPU Fan 1: On top of CPU

those temperatures are extremely high. i recommend checking the CPU heatsink fan to MAKE sure it is securely attached to the motherboard. did you use thermal paste when you installed the heatsink?

fan 1 should be pushing air towards the back of the case.
fan 3 should be removed.

Well I was able to get the temp down

1 66 c
2 66 c
3 63 c
4 63 c

Thats for Idle

With Prime95 I seen temps as high as 77 c thats all.

What is the goal temp?  What else do I need to do?
those temperatures seem a little more bearable. i am not familiar with q9300 temps, but the main rule of thumb is to get the temps as low as possible. if you correctly mounted the heatsink and used the correct amount of thermal paste and you are still getting high temps, the only thing left to do would be to purchase an aftermarket CPU heatsink.

just an added note, when you place fans inside of the case remember to try and keep the airflow linear. the front and side (if applicable) fan(s) should be the intakes and the rear and top (if applicable) fan(s) should be the exhaust. try and setup that third fan in a manner that aids in keeping the air moving in one direction.
