Sudden shutdowns?

by rTypeDelta / May 15, 2009 11:27 PM PDT

Hi, I'd like to ask what could be the problem with my pc suddenly shutting down

My PC spec at the moment is:
AMD Athlon x2 4400 @2,2Ghz
Corsair x2 @2gb (dual channeled)
nVidia GeForce 8600GT (non-overclocked)
Maxtor 80Gb Hdd
3 Case Fans (1 normal, 1 thermaltake typhoon, 1 small one)
Standard AM2 Processor heatsink
500w PSU

latest cpu temp readings,
on idle:
GPU - 49c
HDD - 45c
Core1 - 46c
Core2 - 50c
environment (manual reading) - 31c to 34c

on heavy load: (using gears of war)
GPU - 72c
HDD - 69c
Core1 - 89c
Core2 - 81c

so with all that data, I'm wondering could it probably be the heat? or a faulty PSU? or maybe some software issues.

If its heat i would like to know the normal temperature for it on idle and under heavy load
If its because of the PSU i would like to know what PSU and how many watts should i take
If its because of software issues i would like to know what might be the cause

sorry for the barrage of questions, if any of you need more info to solve this feel free to ask. thank you.

The tests.

I can sniff out heat with the old cover off and point a fan at it test.

But that 80GB hard disk is now popping up all over as a failure point. IF WE ARE VERY LUCKY we see it fail a hard disk test.

Definitely it's heat ....the question is why

are the temp so high ?

Is the CPU overclocked ?

Are the CPU and RAM voltages above spec ?

Checked the HS fan ?

Checked the case fans ?

HDD is a bit hot

HDD should be bellow 60C... Your problem is probably temperature.
But anyway, check out the cables and voltage.

A good software to do some tests and retrieve some info is Everest Ultimate. Try it.

Thanks for the heads up,

I'll try buying everest ultimate and check it out
I'll also be doing some hard drive tests

if its true that it's heat, any suggestions for a heatsink/fans along with suitable PSUs?

Thank you for the solves, it turns out i have a dried out thermal paste. Bought a coolermaster paste and rubbed it in after i cleaned the residue and its stable now

After an hour pushing it with everest's stability test, the heat was stabilized at 50c-60c

thank you for all your help and private messages Happy

Good to hear but still think you need more case cooling

with temps as posted.

You've solved the instant shutdown CPU problem but the other temps definitely indicate the need for more or better case cooling. Isn't that Big Typhoon a CPU cooler ? If yes...that cools the CPU but does almost nothing for cooling the rest of the SYSTEM.
