CPU dead?

SlyOneDoofy · Post by **SlyOneDoofy** » Tue Sep 05, 2006 3:49 pm

Hi,

I was watching a movie on my computer and it gave me a heat warning then shut off. It turns on but it won't post the bois screen at all. No signal gets the the monitor. I don't hear the hard drives kick in either.

It's a Pentium D 830 with a 945 intel motherboard and they have been working fine for about a year.

Is there something I can try to see if the cpu isn't dead and how will I know if it's just the cpu and not the motherboard also?

Thanks!

any beeps? open it up and check for burned parts etc

Also check for dust in the heatsink and fans, reset the cmos, and if it POSTs, make sure the fans are running.

At the very least your CPU is dead. It's possible that your motherboard is fried too, but more often than not the motherboard manages to escape harm in these situations. As for how to tell whether its one, the other, or both....well you really can't. You could probably shell out some big bucks to buy some fancy testing equipment, but its probably not worth it. I would suggest just replacing the CPU. If you put thenew CPU in and your system still doesn't boot, then the board is fried also.

No beeps at all.

If I replace the motherboard and cpu and use a different style of motherboard and cpu will I have to buy win xp again?

If I put in a new cpu and the motherboard is bad will it fry the new cpu?

Thanks!!

No, a bad motherboard will not fry the CPU. As for XP, you may have to obtain a new key from Microsoft, but you do not have to buy an entirely new copy of XP.

It's not so simple. Please reseat all cards, the processor, and memory. Try booting w/ just the memory, vid card and and processor hooked up, see if you get a video signal to your monitor...and let us know if you get Video, if you do, after reseating memory, proc, vid card, then it's another component (fried dial up modems sometimes prevent machines from posting w/ out taking anything else out -- assuming a modem is installed and is connected to a phone line AND a surge has gone through soon).

Based on the error he got, itis that simple. When you add 2+2, you alwaysget 4. When you add CPU+heat, you always get fried. No if's an's or but's about it.

Chips are meant to turn off to help protect them from getting fried, if this protection was on, it should just need to be fiddled with.

that's your opinion.

it can't hurt to do some troubleshooting first before he goes out and spends money though.

SlyOneDoofy, also test the power supply with a multimeter to see what voltage it is putting out, google if you need a guide on how to test with it.

SlyOneDoofy · Post by **SlyOneDoofy** » Tue Sep 05, 2006 9:06 pm

The power supply is an Antec true550 watt. I assume it should be plently and it kicks on and powers everything but no post. I'll fiddle with it tonight and see if clearing the cmos, re-seating everything helps.

Mark... I'll try that I have a multimeter in the garage.

Thanks for all the help and if it's fried I might look at getting the E6700 to replace it and would like some advice on motherboards to go with it.

That's not opinion, its fact. Anyone who knows anything about ocmputers knows that heat is the worst enemy of a CPU. If you want to believe something else, good luck to ya.

YardOfStuf, your correct. However, given (again) the symptoms it would seem that the protection didn't do its job. Common sense has to tell you (if it doesn't it ought to) that when you get a heat warning and your computer shuts off, your processor has become too hot.

Well then what is the point of having chips shut of because of heat if it destroys them anyway? This one shut off and warned me so I would assume it's possible it shut down before it fried.

Of course..... with my luck that's probably not the case.

Gary335 · Post by **Gary335** » Tue Sep 05, 2006 11:16 pm

Well as a computer repairman I know that the CPU would be the first thing I'd check. Just because it shut down doesn't mean it did so fast enough. It had to achieve a certain temperature to get to the shutdwn point, and that temperature is enough to fry a CPU.

LOL!!!!!!!!! I hope you don't assess computer problems the same way you assess people!

Let's get more information: What gave the heat warning? Monitoring software that came with your motherboard? What did it say was over heating? Did you try reseating parts and looking for burn marks?

Can you think ofanything else that would produce such a warning? Also, burn marks aren't always present. If you don't see burn marks, don't dismiss the possibility of something being fried.

"Anyone who knows anything about ocmputers knows that heat is the worst enemy of a CPU." -- Lets state the obvious less and try to help this person. You don't have the machine in front of you, so you can't assume you know the answer. Also, basic math is a poor analogy, at best, to diagnosing a no-post.

You can belittle my analogy all you want if it makes you feel better. And if my statement is so obivous, why do you continue to argue? Thanks for putting your foot inyour mouth on that one.

You can make probable guesses, but that's about as good as it gets without your hands on it.

Those are educated probable guesses. Let's be realistic for a moment: The chances of the problem being anything else are pretty damn slim.

Also, you'll find that a lot of people here are "computer repairmen," and then some.

I have enough experience to match anyone here. Guaranteed. Arrogance? No. Confidence in my many years of experience? Yes.

Are you done with your tantrum now?

Was the HSF on the CPU spinning?

Remove all peripherals you can...PCI cards, cables to hard drives, all power cables except to motherboard, RAM sticks, etc. Even the vid card. Reset BIOS to defaults. CPU removed also!

Now with the system as naked as possible..power up. Any beeps? If so..good.

One by one..begin reinstalling components..CPU...Power up....anything? If so...keep going..next...vid card...then RAM...drives, etc. Powering up between each component you reinstall.

I simply don't take well to rude people. You act like a 17 year old. You have no way to know. Even with the "error" that was given, which could have been nothing more than some trojan or anything else written to pop up a message box, the issue could simple be a PSU issue, even if fans are spinning. Apparently, you don't have the experience to know that. It could be ram, could be the CPU, could be the mobo, could be a modem, etc.

YOSC seems to think it could be several things as well, and I can promise you he has more experience than you do..

SlyOneDoofy · Post by **SlyOneDoofy** » Fri Sep 08, 2006 9:25 pm

Sorry I have been busy with work. I'll pull it apart tonight and see if it's dead. I'll keep you guys updated on how it comes out.

Thanks

SlyOneDoofy · Post by **SlyOneDoofy** » Fri Sep 08, 2006 9:57 pm

OK, this is weird......I went upstair just now and hit the power button and it posted and said intel and I shut if off real quick because I was freaked out it would burn up.

After it shut down the first time when I started this post and gave me the error it wouldn't do anything for 2 days but now it's posting. I'm not sure what is going on now.

I'm guessing it needs a better cooling fan but I'd like to see if windows actually loads up all the way and it's not damaged before I go out and buy a new fan for a broke system.

Here's the question....Do I take the risk of running it until windows loads and see if everything works ok?

Thanks!!!

A_old · Post by **A_old** » Fri Sep 08, 2006 10:04 pm

Yes, run it and see if it posts...AFTER you pop it open, make sure it isn't too dusty (clean it out using canned air and a vacuum if so -- don't get too close w/ the vacuum and don't turn the can of air upside-down though), make sure the CPU fan is spinning and the heatsink is securely fastened to the processor socket.

Also, if you're a smoker, don't do so in the same room as the PC as the tar really gunks fans and vents up.

OK, I made it into XP and gave it enough time to update AVG then shut it down.

What's a good fan for the Pentium D 830 3.0Ghz? I'd like one that can really cool it down because I don't want to fry it again.

And yes Gary335 you were wrong this time.

Your asking me about cooling the CPU on one hand, thenon the other you want to tell me I'm wrong...strange. You even said that you didn't want to fry it again. The CPU may not be fried, but I was correct in saying that the problem lies with the CPU and nothing else. I basically saved you a whole lot of time and trouble by telling you where the problem was, instead of running you through a hundred troubleshooting steps.

ya lets spend money on parts we may not need.

ya troubleshooting takes of time, but time is free, money is not.

of course lets wait and see how this problem resolves.

Save some time at the cost of money huh?

I don;t spend money blindly. Why is it I'm the only one to whom the problem was clearly obvious? Why don't you guys learn a thing or two about computers instead of demeaning my knowledge? Apparently I know something you don't or it would've been just as obvious to you as it was to me.

Then you are the last person who should be criticizing me!

I don;t mean to be critical of anyone's knowledge. I know there are many experienced people here, and I respect their expertise. However, I too am quite knowledgeable, through both personal experience and having been in the business for over 10 years. And I've done rather welll in those ten years. I don't appreciate people criticizing my methods. No more than those people would appreciate me doing so.

As for my age, I am only 21 but I ahve been using and tinkering with computers since the days of the 80286 machines. Heck, I've even tinkered with old Commodore's and Apple's back in the day. I may be young, but I can match just about anyone's knowledge in computers. When I first got into business (at the ripe young age of 11, selling and fixing for friends and neighbors to start with), I was working on 486's and first generation Pentium systems. Now I work on Athlon XP's, Pentium 4's, and all the other new types of ocmputers (there's so many that its hard tolist them all!

). So obviously, I'm not the dumb beginner some seem to think I am.

The computer shuts itself off preventing damage to the cpu.It always been like that but it all depends on motherboard/bios features of course.Usually its set by default at 70-80 degree celsia range.

I said it was the CPU, whether or not it was fried. I did also say that I suspected that it probably was, so don;t get those two statements confused.

I never claimed godliness over anyone. Don't put words in my mouth. My original advice to him was to focus on the CPU and nothing else, which was dead on. I did lateer state that it was probably fried, and that PART was most certainly incorrect.
