My PC shuts off suddenly, seems like a CPU temperature problem

Hello i´m stuck in a very bad situation, i try to use my PC, but it only will remain on for about two minutes and then shuts off, then i try to turn it on again but it will remain on less and less time, until i just cant even get to windows. Then i let it rest for 10 or 20 minutes and then again the same situation i´ve described above.

I checked the PSU and it seems ok, i even changed it for a new one, but the situation is still the same.

I can´t make a ram mem test because it shuts off first, don´t have enough time.

I checked the temperatures at BIOS when i start the PC, this is the status right after i turn it on:

CPU Temp: 75 C, 167 F. (it´s a Pentium D)
MB Temp: 29 C, 84 F.
CPU Fan speed: 3276 rpm. (is this too slow????)
VCore Volt: 1.216 V.
3.3V Voltage: 3.32 V.
5V Voltage: 5.107 V.
12V Voltage: 12.032 V.
Q-Fan: Disabled.

And this are the readings just a minute or two later (without even going to Windows yet):

CPU Temp: 98 C, 208 F.
MB Temp: 38 C:(, 100 F.
CPU Fan speed: 3276 rpm.
VCore Volt: 1.216 V.
3.3V Voltage: 3.32 V.
5V Voltage: 5.107 V.
12V Voltage: 12.032 V.
Q-Fan: Disabled.

And then the PC just shuts off.

Are these temperatures very high? if so, what could be happening, i don`t have it overclocked or something, and in the room the temperature is not so high, it is hot, but acceptable, i´ve been in worst temperatures with no problem at all.


I hope someone can help me, thankx!!!

Cpu at 75C:eek:

tried re-applying thermal paste and made sure you have put the cooler on right?
 
if those temps are right...thats terrible, make sure the fan is plugged in from the heatsink and you may need to reapply thermal paste.
of course the thermal sensors could be bad, but those temps would explain it shutting down...
 
60-80*C is usually the max temp for processors. I wouldn't be running the computer much at all until you figure out what's going on or else you could damage something...

The comment on your CPU fan... It really varies depending on what kind of fan you're using. I've had some that maxed out around 3000RPMs, and others that maxed out around 6000RPMs. The efficiency of fans does not souly rely on the speed they spin. I have some 80mm fans that probably push more air at 3000RPMs than some larger 120mm fans going at the same speed.

Eh, but back to the real problem at hand, the other comments got it pretty much spot on. Check your heatsync. Reapply thermal paste and be sure it's seated correctly.
 
Problem solved! ;)

Thank you guys, the problem was that the heatsink wasn´t seated correctly, now it´s running normal.

Thanks!
