Did you check your computer temperatures?

[alkimia]

yes ...i have 8 fans and 1 big cooler dont think thats the problem

[Broni]

What's the power supply wattage?

[alkimia]

well my power supply  is  of 750watts

look i just look into nvidi monitor and it says 61C° video card ...58° mohther board ....67 procesors

should i get worry?

Not sure (my computer keeps around 50c) but you can try facing an external fan at the computer and see what happens.

Idle? Is it AMD, or Intel quad?

[alkimia]

intel quad

[Broni]

Idle?

[Broni]

core 2 quad 2.4 max temp is listed at 62.2C, so you're melting it, idle, or not!

[alkimia]

so what can i do...?  idle? whats that ? and look i bought a cooler for this pc why is not cooling .?
i see it working so what could be wrong?

[alkimia]

so should i put the original cooler?

[Carbon Dudeoxide]

Idle - when the computer is just sitting there, not doing anything.
Basically Broni is asking what were you doing on the computer when you posted those temperatures.

Can you try my suggestion?

[alkimia]

oooh... well i i was playing
crysis and it crash and had to restart it and after that i look temp

i cant try your idea man... dont have space....
should i put the original cooler from the processor?

[Carbon Dudeoxide]

I meant leave the fan outside the computer and face the fan AT the computer.

You were playing Crysis? I REALLY think it's an overheating problem.

What are the temperatures when you turn on the computer and leave it for 5-10 minutes. (idle)
