My computer shuts down randomly????

HP Pavilion dv1000
January 18, 2008 at 13:15:47
Specs: Microsoft Windows Xp Home, 222 1.40 ghz
Ok, First off my computer shuts down every time i try to run Disk Cleanup Or any other important program, like installing something, browsing the internet it randomly shuts down and when it gets really hot i cant even start the computer up because when i login it shuts down. So then i wait like 30 minutes for it to cool and it starts succesfully, but still the same problem when i run programs, or disk cleanup it shuts down randomly.

Your problem is "it gets really hot"...that will HAVE to be fixed. Either your CPU cooling fan isn't working or your laptop is full off dust. It will have to be opened up & cleaned.

Start at the event viewer logs.

I read it wrong and answer it wrong too. So get off my case you peanut.

Never mind the 'Event viewer logs'. Fix the overheating problem, like Jam suggested.

If this is the computer listed in your first post apparently it's a notebook computer.

If you're running it on an old main battery when you have these problems and not on an AC adapter, it may need a new battery; it may need a new main battery even if you do run it on an AC adapter when you have these problems.
E.g. a friend has a HP notebook not much newer than this and it's original main battery is on it's last legs now. They work as they should for a year or so, then they begin to deteriorate rapidly. Your model came out in 2005 or late 2004 - if it still has it's orginal battery it may be more than 3 years old.
Or your AC adapter may be defective.

See this - you're going to have to get inside it's case and check it out if you want to see if you have a mung buildup or a cpu fan problem:

I fail to see how disk clean up has to do with temps.

Use the help and support pages in XP. Search for event viewer. It is also under the admin tools. Says "event viewer". See the times. You can get more info if you click on or copy and past.

After dealing with overheating download the "microsoft memory diagnostic" and run it.
You'll need a floppy disk.

I've been having shutdown probs as well.
Installed all new items:
cpu dual core 1.6
asrock sata2 mb
1g 667 ram
450w power supply

After running for 1 1/2 hours the system shuts down with only the floppy, the vid card and the keyboard attached.

It passed the extended memory test.
But if I go to the bios screen where the cpu temp is and wait for shutdown I see that upon shutdown the

cpu temp is 31C
case temp 28C
and fan is spinning at 2023rpm

This is for a e2140 dual core 1.6ghz processor.

Hardly warm?? Any Suggestions?

The most likely thing is you have a defective PS.
Failing power supplies are common and can cause your symptoms.
If your PS is an el-cheapo brand and model, it is a lot more likely to cause you problems. If you paid less than about $40 for it, it's probably a piece of xxxx.
Check your PS.

Thanks for your help but I unplugged the power button lead and replaced it with the reset lead and it works like a charm. Must be a problem with it.

I got an email from a friend who suggested this. Something to learn here - think outside the box.

The cpu is at 36C and humming nicely.

I find that hard to believe. The reset & power button are similar to a doorbell button...press to make contact, release to break contact. There's really nothing to them other than two contacts & something that acts as a spring to keep the contacts separated.

Well it's still a touch early to be totally sure on this but I'll leave it to run overnight and let you know tomorrow. I am feeling confident on this however as all the parts were new and I tried all of the "usual"
fixes.

That can't be it.
The switches can't cause the computer to spontaneoulsly shut down after it has been running for 1 1/2 hours.
The PS is still the most likely culprit.

The power and reset switch on an ATX case are "momentary" switches - they are on only when pressed - the rest of the time they do nothing and are not needed. Normally neither can possibly make your computer shut off when they aren't being pressed.
Defective power or reset swutches are extremely rare - if you have any problems with them at all, it's more likely to be because of a button that presses on them is sticking, or a poor connection of the connector for it to the mboard pins for it.

So what about the extremely rare case of the switches sticking on or shorting?

If the power switch or it's case button sticks in the on position, or the switch shorts, what happens depends on bios settings, but the usual thing is the computer will shut off after about 4 seconds - either that or the computer will probably shut down Windows properly (soft off) immediately. If the switch or it's case button is still stuck on or is shorted, the computer will not start up - the connection has to be broken briefly - no connection - open - before pressing the power switch will boot the computer.

If the reset switch or it's case button sticks in the on position, or the switch shorts, the computer will shut down and never restart unless Windows has frozen such that the reset switch has no effect.

I'm very impressed with your knowledge of the power and reset buttons but let's wait and see how reality plays out. I have a stopwatch on it and I'll post the results tomorrow. It has never run longer than 1 1/2 hours before "mysteriously" turning off.

Do not post back here VwV. We all know the switch isn't your problem.
When it fails again open your own post. You butted into Manny82825's thread and that is not acceptable behavior on this forum!

I realize that vwv hijacked this thread, but the OP hasn't been back so I went with it.

@ vwv,

Apparently you're not gonna post your PSU specs? As aegis put it, "We all know the switch isn't your problem." Several of us suspect that you have a cheap generic PSU with crappy specs, but we have know way of knowing. Post back with the make/model & the amperage ratings on the +3.3v, +5v & +12v rails. If you don't have the info, open the case & get it off the label on the side of the PSU. And once you get that info, start your own thread & post it there.

OK sorry about butting in on Manny. I apologize for that but it looked as though he was going to be occupied for a bit enacting your suggestions so I slipped in with a similar problem. Seems you're angry that it was in fact the power switch and not the power supply that was the culprit. I'm as surprized as you are but thems the facts.

After I unplugged the power switch lead from the pins on the mobo and then plugged the reset into those same pins my computer:

1. Stayed on all night displaying the bios screen which has the temps etc. (36C by the way). I powered it off after 10 hours of being on - never happened before.

2. Left it off for 1 hour to see if it would
start up on its own - which it was doing - and it did not.

3. Ran windows memory diagnostic (T mode)for almost 4 hours - was on the 11th test of the 4th pass when I was convinced it was running fine and I shut it down.

I don't know what to say but, sorry my PS was not the problem.

I'm not making this up and if you want to fly me and my computer to you I'll do it just to show you.

For the record my PS is a cheaper one.

For the record, your PSU is a piece of sh*t. If you wanna risk the life of all your important components on a $22 PSU, that's your business...don't say you haven't been warned.

Also for the record, I don't believe the power/reset switch had anything to do with your problem, but if you're happy with that explanation, enjoy!

If you guys want to be stubborn then that's what you'll be. If you were open minded you would have noticed that my 2nd point was the important one. The PS does not initiate the computer turning on the mobo does via a switch. If my computer was turning on without any initiation from me then the board was doing it somehow. That somehow was through the faulty power switch and/or lead.

Try to understand the simplicity of this:
-Computer not working properly
-unplug computer PS
-unplug power button switch
-replace it's connection with reset switch's
-plug PS back in
-press reset switch
-computer works without turning off

In less time than it took me to write these points I did it - and nothing else. This was not a miracle! If you are logically inclined then you will have to say this operation had a positive effect.

If you don't want to learn anything new then keep on posting amongst yourselves and disregard the input of others.

Sure the PS could be better but I will only be powering a floppy, a sata drive, a dvd burner and a radeon 9200se video card.
As I mentioned before the dvd and hard drive are not presently installed. I had one of these PS in my previous computer and it lasted 8+ years.

You're the one who's being stubborn & closed minded...what you're saying is REEEEdiculous!

I think YOU need to understand the simplicity of the power & reset switch. There's very little that can go wrong with them. As Tubesandwires explained, it's just a "momentary" switch. You press the button, the circuit closes, the power supply receives the "power-on" signal & it fires up. As soon as you release the button, that's it...it's completely out of the mix & has NO bearing on the system WHATSOEVER until it is pressed again. The reset switch works exactly the same way.

Try switching them back again.

"Sure the PS could be better but I will only be powering a floppy, a sata drive, a dvd burner and a radeon 9200se video card"

Don't forget the CPU, motherboard, RAM, sound, network, fans, keyboard, mouse, etc. Or didn't you realize that they require power too? ;-)

Yes that's true but is too obvious to require mention.

Stubborn is not acknowledging the facts when the facts are unpopular.

1stly you did not respond to my point about the computer turning on by itself.

And secondly if as you say the two switches cannot be involved why does the power supply, if it is the culprit, suddenly work properly and not shut down the box when the switch is made?

And yes, by switching back to what I had before, the computer shuts down.

Anyway I hope Manny has his computer working properly as mine now is.

Obviously, VWV, you aren't using logic.
You did something else that fixed the problem, whether you are aware of what that was or not.
We didn't say the PS caused the problem.
We said it's the most likely cause of the problem, especially since it's an el-cheapo PS.

I will test the faulty power button on another working computer and observe the result.

You are telling me what should happen I'm telling you what did happen.

And this business of " (I)did something else that fixed the problem, whether you are aware of what that was or not." is a cheap argument.

If someone told you this, knowing you in fact did nothing else other that what you said you did, you'd think it cheap as well.

No, it isn't.
There are other things that could have caused your problem but they're not anywhere near as common as a faulty PS.
Your rejecting our info regarding it couldn't be either of the switches that caused your problem defies logic and signifies there no is point in us trying to argue further with you, and I am probably going to avoid answering any posts made by you in the future.

I put the switch in another box and it shut down as it had in the other computer where it was installed. I guess it's illogical to think that a switch can fail.

If it shut down right away that's entirely different from it shutting down after 1 1/2 hours - it cannot cause the latter.
