First off, i'm typing this message with my Wii, so i apologise for the broken grammar and brevity.
My pc is currently giving me huge issues. my p4 3.4 prescott is booting at 45C and continually rising to 100C, even when in the bios only, from a fresh cool boot. i've touched the heatsink, and its really getting that hot. fans are working. just randomly started doing this. windows xp boots but my computer forcefully shuts down after a few minutes. heatsink and paste are on properly. any ideas anyone?
Thanks,
~Dac

QUICK! OPEN THE SIDE OF YOUR CASE AND SPLASH THE MOTHERBOARD WITH ICEWATER!!!!

Ok, just kiddin'...

Questions:

1) Is this a recent occurrence?
2) What HSF are you running?
3) Are you OCd?
4) What are utilities like TAT or SpeedFan reporting?
5) When you reboot after a hard crash are you doing so in Safe Mode?
6) What is your CPU usage at idle? (McAfee has this evil utility that randomly decides to run your CPU at 100% just for the halibut)
and last but not least:
7) 100C is not a record for a Prescott. I've seen 'em run hotter than that. But the crashing is worrying.

PS. All kidding aside, what is your ambient temp? Was the CPU just recently installed? If so, you should make sure(recheck...w/e) that the heatsink is making proper contact with the CPU. Also, this may sound obvious, are you sure the heatsink's fan is working(properly)? Even if you had a virus/trojan causing 100% CPU usage, it shouldn't get that hot. GL :)

1) Yes, very. My CPU has always been a bit hot, like 50C or so, but nothing like this.
2) Stock, with AS5
3) No
4) Not sure, can't really get into Windows. BIOS says the fan is at around 2300 RPM, or whatever normal/fast is.
5)Yes. Even when I don't boot into windows and just enter my BIOS to check temperatures, it starts at around 45-60 and slowly rises to 100C and beyond.
6)Normally it's around 2-3%. When it started doing this, I noticed it was around 7-18.
7) My BIOS doesn't report anything past 100C, so it's possible it's getting hotter. Plus, I didn't want to leave it on to find out how hot it could get.
8) Nope. =P

hey there

there're some extremely relevant questions from other posters.

I would like to ask, what is the ambient room temperature where the pc is located, have you checked your bios voltage settings, and, as another point, have you tried swapping out the psu with another? also, how exactly are your fans positioned? if you havent got em installed correctly or something to maximise efficiency of airflow, then they're just for show.

not dissing, just trying to collect info you know? i thought that the absolute heat tolerance was about 100 deg. c, so i thought that your chip was fragged, but glad it aint. that would've sucked hairy bollocks.

Penis Fly Traps, Sucking Hairy Bollocks, is there something in the air today? :lol: 

Good points Triatium and Tanker. Dacvak, I think we may be running out of suggestions. It certainly is strange. Prescotts run HOT. That's common knowledge. But around 50C under most circumstances is usually the norm with some really heavy usage spikes around 60-70C. They can be coaxed to over 100C but it really isn't a great idea. Something is using your CPU, but nowhere near enough to run the temps this high.

Prescott's are one of, if not the hardiest chips going. I have a 2.4GHz Prescott , and it's highly O/Ced. One night i was watching tv(comp was ~ 6 feet from me), and i smelled something burning . At that time i was running it @>3.8GHz(1.575v) with an XP-120/120mm 86cfm fan. I looked in through the case window, and the fan had stopped. I looked over at the MBM icon in the sys. tray, and it read 95C. I shut it down, no probs...still running @ 3726 1-1/2 years later. They may get little to no respect, but they are a tough chip. :wink:

room temp is 65F. voltage is at defaults. fans are positioned fine. this computer ran for a year with no overheating problems. i'm not necessarily looking for a solution, just ideas on what the problem might be. everything is properly seated and installed. this just started happening.
February 7, 2007 6:20:33 AM



I love those pix of the motherboard in the snow pile! They should just attach a 1.1KW PSU and boot 'er up! :lol:

I think I'm at the end of my ideas. Can't really see any reason why the thing turned into a furnace all of a sudden.
February 7, 2007 6:23:19 AM

Did you ever replace the heatsink yourself or take it off and put it on? Don't know if it is actually possible, but maybe your thermal paste dried out. You could try reapplying the thermal paste if you know how. Google it, there are a billion topics on it, not to mention guides :wink: .

Dunno. AS5 is damn good stuff and you'd have to really abuse it to dry it out.

Yeah. It's gotta be something that just happened. What's the Vcore reading? Maybe something went south on the motherboard or the PSU or???

Oh, BTW, Tanker... The local forecast for Sunday is +28C and sunny. I take it that it might be a touch cooler in your neck of the woods? :wink:

what model of CPU heat sink are you using and how many case fans do you have?

also do the case fans take air out or bring air in? or what?I think everyone(almost)is missing the big picture here. Even with no case-fans, 100% load, and a sh*tty HS/F, it still shouldn't be hitting 100C. Either some mobo component is failing, the monitoring chip is malfunctioning, the HS/F isn't making good contact with the IHS, or something crazy has happened to the processor's innards. :wink:

100% Agreed. Time for a CPUxorcism. :D 
February 7, 2007 7:42:18 AM

100 C is too much..under any load!!!
I have a few possibilities for ya:
1-your temp sensor is nuts: (if it starts at 45 and the system doesn't crash at 90...it means it's the sensor)
2-if indeed it does crash, but it still starts at 45C and your fan is working at full speed, that means your paste is dead, but probably that your CPU (you say it always ran too hot) is faulty right from the start, and now leakage has gone too high.
3-if you installed a new case fan behind the CPU, or for some reason a new power supply with a strange airflow, this could cause the internal air flow above the CPU to go in a closed loop, thus no longer evacuate heat..

So 1-check your fan, 2-clean up the CPU radiator(dust can get in tremendous amounts in there....just blow some dry air in it) 3- open the case, get some large 10$ fan from the store and shove it right in front of the opening....it will get any CPU(as well as your feet) ice cold....

I once did that with my P4 RD RAM PC1066 (yeah, the bill still hurts)..i was running it for 4 days under maximum CPU load non stop (compiling) ...so the extra 15 inch large fan came in handy

The thing that makes me think the temp sensor isn't the problem, is that the HS is (apparently) quite hot to touch. That means that it is, in fact, dissipating a lot of heat. My overclocked Prescott is pumping >1.5v, and even though i have a great HS/F(XP-120), it's never..ever, hot..or even barely warm. :?

When did you buy that? Didn't RD-RAM come out around 2002 when 512MB of 400MHz DDR RAM was uber?

As for the 100C cpu? I'm saying faulty sensor. I honestly would have though that the CPU would have been melted at that temp though.

Nah. Nobody believes me but I've seen a Prescott run at over 110C. Verified.

Hey, if I state something is the truth you can take it to the bank, dude. What about the time that I had explained how I OCd my 3700 San Diego on air to beat the IBM's Blue Gene/L prototype's 135.5 TFLOPS? :lol: 
February 7, 2007 9:28:31 AM

Sup dude

Phew! ADSL's been lagging like a molass on a cold day! AND net been giving hell my end!

Anyways, I reckon that the psu should be checked out. also would cover any faulty connection issues from the cords side, at any rate.

Im plumb out of ideas. Maybe the heat sensor is faulty?

Didya hear about that massive DOS attack on 3 out of the 13 main net nodes going on right now? I haven't felt any effect of that here, but maybe it's hittin' where you are?
February 7, 2007 9:53:02 AM

Nope, aint heard jack. Serious? any details on the story?

Besides, our carrier messes things up six-love without anyone needing to put their two cents in - probably the dos attacks are the reason why its clearing up now! *grim laugh*

Besides, we're running on old lines that are at least 5 years overdue for upgrading to handle increased signal bandwidth. Let me not open that can o worms!

Anyways, aside from psu and sensor suggestion, slap a TEC or phase change onto it! Hehehe!
February 7, 2007 10:07:16 AM

Must have been 2002... the good old (expensive 850 EMVR with 533FSB...quite balanced with that 1066 RDRAM)....Quite expensive too. I learned my lesson: even if the thing is better, stick to open standards (DDR vs.Rambus)..provides a safer upgrade path.(RD PC1066 still costs as much as it did back then...on ebay)
February 7, 2007 10:34:46 AM

I'd think the CPU's shorting out internally or on the mainboard socket. The heatsink is getting quite hot so there obiously some contact with the cpu... unless it was eliptically shaped or sumthin

Dude is your motherboard covered with dust, I mean really caked with dust. Use a air blowr or something to clean it and then try running your pc.
A friend of mine had a similar problem and his pc was continously crashing, turned out that the dust was increasing the resistance of the circuits and making the pc behave like it was extremely over clocked(like the voltage across it was too high).
February 7, 2007 12:57:56 PM

Dust doesn't add to the resistance of circuits....coz it can't get in series with the circuit. what it can do is create a parallel circuit which will diminish the resistance of the circuit thus incrreasing current (i=v/r) as a consequence, heat increases p~Ri² or better yet p~V²/R.... Moist dust might even fry your MB by creating a short-circuit. But long before then, dust will block your VGA radiator (easier than the CPU radiator) and get your VGA to crash the system.

Honestly, if u can test another CPU, do it....if you overclocked or modified something, roll back. Else, get a bigger fan and hopefully u'll make it through the quarter without frying ur CPU.

It's been in the single digits to teens here recently (before wind chill, which has sent it well in the negatives). My roommate has the side of the room with the window, otherwise my P4 system would be sitting securely on the ledge on the outside, ^^

Sell it on ebay; I'm sure there's a tech n00b who will buy it from you just so they can brag to their friends.
