Computer turns off during xp installation

[teken894]

I recently assembled a computer:
Abit SG-72mobo
CeleronD 2.93 ghz cpu
512 mb pc2700 memory
seagate 80gb hd
memorex DVD+-RW
and 300w antec PSU.

All are new except hd, memory, and cd/dvd drive. All old parts are known working.

BIOS POST shows up, with all correct info, with halt on no errors. IDE devices are recognized

Then, i boot from CD, and windows setup loads. Then when it says "Setupis starting windows" the computer turns off after a couple seconds. Sometimes i briefly see the welcome screen before the computer turns off.

I've tried the microsoft article that says that the processor may be too hot, and it automatically turns off, but the resolution did not work. I tried the standard HAL, but still same problem.

the turn off problem also occurs during other times. I've tried memtest86, but the comp turns off during 3% of pass 1.

I've tried replacement mobo (machspeed PM2MP), PSU (250 watt generic), memory (512 pc2100 viking). All don't work.

Only problem i can spot is a defective processor or bad heatsink. (PCHealth status says 85 degs in BIOS). I have installed the heatsink properly (copper disk touches processor).

Is there any other problem associated with power turning off....it's the processor ain't it.....

never had a cpu failue before, and never had experience with defective CPU. Also, I've installed redhat 8 successfully, but then it hangs too after some time

some help please...how can I cool down the processor. And can someone tell me what should and should not work if the processor is bad.

If the BIOS is reporting 85 degrees C that is your problem. Did you use thermal compound (Arctic Silver or similar) between the heatsink and CPU? And is the fan actually rotating?

 

[teken894]

Yes, I have an ATT heatsink that came with fan.
fan is working.

Sounds like the celeron is junk, as long as you're absolutly sure the rest of the components are ok. Did
you contact Abit support about the problem?

 

[teken894]

Are you saying my CPU is overclocked or somethin. Its defective??

I'm pretty sure that the mobo is OK. I'll call ABIT anyways

 

[jward52]

I think you'll find that the celeron is defective.

 

[paparazi]

Sounds dumb but does this motherboard support a prescott core CeleronD?
Only other thing I can think of is bad memory module.

And the 85 is 85f not centigrade? please confirm.

ya, its 85 degs CENTIGRADE

On a fresh cool boot, he CENTIGRADE Temperature is 53


And I think my processor is slowing down to stay at a max operating temperature of 85 C. A game starts quicker than it did on my old 1.1ghz cpu, but when "loading scenario" the load time is MUCH longer than my 1.1 ghz cpu. Like 10-15 seconds longer. this may not be a cpu problem, but don't know.


Also, haven't gotten around to getting thermal paste (Artic-silver or Coolmaster) yes, I'll apply and see what happens.

With your last post, it appears that you arent using any thermal paste at all? Or did you use a standard thermal paste and you are referring to getting a better quality?
If its the latter, i would like to know if that helps you or not.

I keep coming from work late everyday and going to get some thermal paste today.

No, I am using NO thermal paste as of now, and i'll get back to you if thermal paste helps or not.

Here's what I've managed to try so far:

Using a HUGE fan to blow into the computer...
Results:
Idle temperature decreases from 56-66 C to 47 C.
I ran the comp on 100% CPU usage for 1 minute, and the temperature went back up to 85 C. Then the CPU throttles at 85.

I think that would be a CPU core problem or something, I'll try to get some thermal paste on there, and see if that helps.

Also, my heatsink fan doesn't seem to be as effective as I'd hope it'd be, I'm going to try getting a new heatsink also.


I'll reply with any results.

 

[garebo]

The heatsink fan combo, is that what came with the cpu, as in retail package?

I have never heard of running a cpu without thermal paste between the cpu and heatsink before. I guess i just learned it and always did, didnt know you could go without.

The CPU may have the factory stock yellow plastic "goo" between the CPU and heatsink. If so, remove the heatsink, carefully scrape all the "goo" off with a fingernail or wooden stick (no metal!). Clean the heatsink with high grade alcohol (90% or above). Put a grain of rice sized dot on the CPU and spread. Put the heatsink back on (correctly - not backwards).

 

[teken894]

I've fixed the overheating problem.

Got a Zalman CPU cooler, and some Artic Silver 5.

During the installation of the new heatsink, I noticed how tightly I had to place the heatsink--I was afraid to break the processor or something.

Anyways, the otehr heatsink I had was nowhere as tight (under pressure) as this one, and I think that there may have not been enought Processor-to-Heatsink contact on the other heatsink.

Also, now with thermal grease/paste I've secured the Processor-heatsink surface connection.

Thermal paste DID help, but most of all it was my heatsink not touchin--with enough pressure--the processor.

Thx for the help, the celeron thankfully is not defective

thx

FYI:

My temps after upgrade

CPU --> 33 C Idle
--> 45 C Full usage for 5 minutes
Case --> 35-37 C Stable
HD's --> 41-45 C Idle-Acccess

Good for you!
Also, it takes many hours for the thermal paste to settle into all the small holes in the surface, so you will get better temps by next week. Its pretty much always best to use smallest amount of thermal paste you can. But if you find your temps going up next week instead of down, then perhaps a bit more thermal paste to fill the holes, which holes are so small we cant see them.

Not needed now, but, maybe on another mobo, another setup.
I've seen videos and tutorials where you sand the finish on the heatsink where the heatsink meets the cpu, make the finish shinier and better than the stock finish and you get much lower temps. You use standard sandpaper, start with around or below medium grit and finish with very very fine, you can get a mirror finish. Again,you dont need it now, just giving some more info.
