Computer Hangs anytime and anywhere

[manan]

Hello guys,

I have Computer hangs problem. Computer hangs anywhere sometime in bios too, before POST, after POST, during work, and even in safe mode.

So acc. to me its a hardware problem.

I kept my computer open so heating of cabinet is not problem but I thought my CPU heat sink may have problem. CPU fan is working fine.

Ram is ok, I already tested memory test and it shows no problem. Even I tried to removed one ram and test computer.

Power supply also seems fine, because I tried to use another SMPS same problem shows.

My Cabinet fan is jam, but I aready kept my CPU so that fan does not make much effect I hope so.

I have doubt on heatsink but not sure or may be its thermal paste ?

I already checked Events logs no new logs shown currently all are old one.

Here is my computer config:

Processor : P4 2.4ghz
Ram: 1.12 Gb [1 GB +128 MB]
[strike]MOBO: P89v51RD2 [/strike]
MOBO: D845GVSR
Gfx card: No

* Edited mobo model earlier post wrong model.

^+1 exactly the hdd is damaged and will eventually fail.
Get all your data you want now before it's too late.
HEXiT is also correct that power surges and spikes cause the most damage to hdds.
How many times has the power gone out with your pc running?
It's happened to all of us.
Good idea to have at least a surge suppressor between the wall and your psu.
Also check out your psu with a multi-meter or tester.

Hmmm Today only one time computer freeze, I used computer for nearly 4-5 hours. Problem is reduced much, I don't know how.

In few days I am going to install fresh window. Completely format the HDD all drives and then will test HDD using segate software.


1. I tried replacing PSU
2. I already test Memory.
3. Heating is not the problem, becz if computer hang or shutdown becz of heating prob next time when it we turn on it produces particular sound sequence an d even msg appear on screen before POST.
4. I monitored HDD temp is normal. I don't think there is any sensor for CPU temp in P4.
5.Mobo caps are absoultely fine. Cann't say if any other Hardware defect is there.
6. Already cleaned lot of times, Heat Sink+CPU and every time I applied fresh Thermal paste.
7.CPU fan is working fine as I can see.
8. One side of chasis is open, So I dont think there is hot air or heating problem inside chasis as P4 procesor does not produce much heat.
9.Already tried to remove all cables,RAM units,processor,fans,HDD,CD Drive from mobo and reconnect them.
10 Few months ago when i try to install OS, at that time also it ill hang in between [You know how irritating it is when Pc hangs during Os installation lol] Will try to reinstall OS in few days again.
11. There is not the problem of drivers[updated] or any software I suppose. Becz system freeze anywhere anytime.

thanks,

@davcon

I canot say anything how many times system freezes and forcely turnoff. I never counted But it happens lot of times.

I will check PSU again with multimeter.

who makes the motherboard - is it a foxconn

 

[manan]

Actualy I bought this brand new LG system that time and motherboard manufacturer is intel corporation as shown in CPU-Z.

 

[Hellboy]

is there any markings on the motherboard it self...

cant find any trace of the board that what cpuz gives up

unplug the hard disk

reset the pc for a while spazmodically and see if it hangs at the bios

if it does then its not the hard disk

i had a cd drive fail once - it had a circuit board fault which caused the booting issue - one of those cheap ones - an obscure make - cant remember but theyve gone bust now so its not important anymore. ages ago that !

with onboard video cards it uses the ram of the machine - take out the odd memory and see if it boots ok then swap memory chips and see what happends..

as i say if i think its the motherboard but hey ho, if its the same motherboard that E-Machines used then they were problematic with motherboard issues.

again you have proven its a hard drive issue, you reformatted and reinstalled and the problem went away for a few hours...

now pay attention to it over time, the pc will start shutting down at shorter and shorter intervals. it may not follow and absolutly straight path in the time it takes as you will be doing different things. but as a general rule the time between shutdowns will decrease... as more and more bad sectors are written to the disk.

replace your hdd... you may have to get a 80gig+ as i dont think they make 40 gig any more.

 

[manan]

There was not any marking on the system. Can you give nay clue what sort of marking you are talking about. Only intel logo and board name and barcode is printed on circuite board.

I already removed the CD drive So this option is also neglected than becz of CD drive this freezing problem arose.

As i told these days its did not hang much today it hang which is tun on PC[ after complete login when desktop window comes] then i restart the PC usig reset switch and work conti for 2 hours it did not hang.

So in such situation, its difficult to weather system hang in bios by removing HDD.

Already tried by swaping RAM earlier at that time it does not effect the Hang ups, they remain same

No I didnot install OS recently, its old OS. I was saying in above post I will install in the coming days.

its normally in white writing on the board or on a sticker with a bar code on it...

it can be quite subtle but atleast we could have further insite to what board you have.

you could reflash the bios if we knew exactly what board you have

but hey get a Asrock socket 478 on ebay for about 30 dollars if this is the answer to your problems...

try a ide hard disk - someone you know must have a 80 gig or something knocking around..

download burn in test pro - theres a free trial - google it and see what happends

 

[manan]

If you are talking abt my board name its:

[strike]MOBO: P89v51RD2[/strike]
MOBO: D845GVSR
Socket 478

I already mentioned board in my first post, There is bios update available of this system, But I dont think its BIOS issue becz this system working fine with same bios few months ago and slowly this problem starts.

I did not update BIOS becz I fear if it hangs during BIOS update then it will create problem. Then need to restore the bio bla bla..

my bad i misread your post...

I will check PSU again with multimeter.

Which is the first thing one does for this kind of problem. Most everything that causes your problem is not identified by observation. Most of the things you were told to inspect do not cause crashed. Those 'solutions' cure symptoms.

A multimeter must measure six wires both before and as the power button is pressed. Critical wires that connect the PSU to motherboard are a green, gray, purple, and any one red, orange, and yellow wires. All measurements must be done with nothing disconnected or removed. Numbers reported to three digits.

The next reply will either say what is suspect. Or what is completely good - without any doubts.

I did not see what is the computer manufacturer. Better manufacturers provide comprehensive hardware diagnostics. Otherwise you must download diagnostics from various component manufacturers. Again, most all failures cannot be visually identified. To have solutions that are definitive (without doubt) means hard answers such as from a multimeter and from comprehensive diagnostics.

Was your heatsink locked solid with dust? If not, then heat was never a problem. Heat is a diagnostic tool that finds defective hardware. Should the meter only report parts as good - without wild speculation - then a heat source (ie soldering iron, hairdryer) may be another tool to identify defective hardware. After measuring with a meter and posting those numbers, then start looking for available heat sources and comprehensive diagnostics. So that we can move on to answers without speculation.

@westom

I already tested PSU as i mentioned, even tried by changing SMPS with higher wattage.

I said i will double check PSU again.

My heatsink is totally cleaned.

 

[westom]

I already tested PSU as i mentioned, even tried by changing SMPS with higher wattage.

All that is completely irrelevant to what a meter is measures. You are assuming a PSU is the entire power system. PSU is only one component of that system. Higher wattage PSU also makes no difference.

All that concern about heat and other visual indication is mostly irrelevant. Most problems involve things that cannot be observed without test equipment such as a meter.

Either keep finxing perfactly good parts and software until something works. Or do as suggested to see a defect before fixing anything. Currently, those who better know computers cannot provide assistance due to insufficient information. Things you already did only rarely explain your symptoms. Useful replies (without speculation) start with numbers; ie from a multimeter.

@all plz note:

My mobo is : D845GVSR [intel board]

I mistakenly post wrong model in earlier posts "P89v51RD2" . Actually I was working on Microcontroller, So I confused with this. lol @ me.

Sorry for wrong info.

Ok Today i keep system on in BIOS without HDD, HDD data cable was unconnected. and yes system hangs in BIOS. and also during CHDSK it shows " 0 KB in bad sectors."

I suppose HDD is fine.

@ westom
I will update PSU results tomorrow, after testing PSU with multimeter.

What do you mean by "those who better know computers cannot provide assistance due to insufficient information."

You mean that i do testing is not worth :O or nothing anyone can predict from such testing ?

Even SMPS wattage prob also one of the reason os sytem shut down and hangs. [ Try to use Dedicated Gfx on your system and use less wattage SMPS you will results ]

thanks,

 

[manan]

Lemme post some SS of CPU-Z, If anyone needs info about my system:

Here complete CPU Z info:

1. CPU

2. Cache

3. Mother Board

4. Memory

5. Memory Slot 1

6. Memory Slot 2

7. Graphics

Hope it helps.

Normal is for a good supply to fail in what is otherwise a good system. Normal is for a defective supply to boot and run a computer for months or even a year. Swapping (testing by subjective reasoning) leads to speculative conclusions. Does not provide the hard facts required to have definitive answers.

I cannot say anything useful from tests done by swapping parts. It is too speculative. Will only result in replies from others who only understand a 'yes or no' world. The real world is ternary: 'yes, no, or maybe'.

To provide a useful answer, I need hard facts such as numbers. I cannot add anything from testing that creates doubts.

For example, the power supply could have been defective when installed. Still booted a computer. Then caused failure months later after the warranty expired. But the meter would have seen the defect immediately. Long before the defect causes any failures.

A first thing we must unteach some techs is shotgunning. Diagnostics that only provide 'maybe' answers. We need faster answers - without doubts. In most cases, that always means numbers.

 

[wolfram23]

If you don't have a multimeter, you might get some answers in HWMonitor. It depends on what the motherboard can show, but for example HWMonitor has 3.3V, 5V, and 12V actual voltages so I can see if they're way off. Even with my system fully loaded my voltages barely drop, only the 12V hits 11.83 at the absolute lowest I've seen, normally 11.88V. ATX spec is something like +/- 0.4V I think.

 

[manan]

@ Wolfram23

I am electronics guy I have Multimeter. and I will post HWmonitor result too if feasible(sensors)

@westom

and yes I already did testing with multimeter 6 months ago that time SMPS was ok, then at that time I try to replace SMPS too, but no use, thats why I am saying in above posts that i already did that and I will do these test again.

If SMPS will ok then whats your next move (for test)?

Can you plz explain it in easy words/procedure So that everyone can understand what actually you mean, no offencee

 

[ghnader hsmithot]

you want to test your psu with the multimeter right?

 

[westom]

Can you plz explain it in easy words/procedure

Use the meter as described to measure those six wires. Post the resulting three digit numbers. A reply may define information from those numbers that you did not even know exists. I don't know how I can make this any easier. Numbers using that posted procedure is necessary for a useful reply.

 

[Hellboy]

Testing a psu with a multi meter will only work out if 12 volts is there etc

it will not give you the wattage or the ampage drain..


good grief...
