computer soon to blow up

[System]

Hello again everybody,

i've posted about this earlier but just to recap it - I have an old dual P4 CPU system (yes two individual p4s) that screams like someone is getting raped. Now I'm not sure exactly where the sound is coming from, as it is so high that you cannot pin point its exact location from the MOBO. I am assuming it is a CPU related issue as for the following reasons:

A) computer has not run for hours, come to boot it up. Moment the CPU sounds like it is running, the noise comes with it

B) during a benchmark test, CPU FPs drove my CPU(s) mad and the noise returned

C) more frequent lockups, freezes, deadlocks, whatever you want to call them, the system just stops in its tracks. This started ocassionally on boot ups but today has occured on the desktop right after booting up.

D) CPU usage has increased dramatically. Very slow over nothing. Then resides back to normal conditions.

E) when scrolling down a web page not to long after boot up, using the scroll wheel will cause noise

F) Yes, the noise eventually goes... 5-10 minutes none stop during boot up/after boot up and 5-10 minutes of on/off noise to follow up. Becomes longer.

G) None related to CPU but BF2 use to be unaffected. Now it screams sometimes while in BF2 stats. occassional I could swear my computer is lagging now while playing but then again, I'm also on satelite. PING changes as fast as the weather does.

Ok so there you have it, a computer destined to blow up. My question, I'm getting so F'n frustrated trying to pull out the CPU's on the MOBO and there seems to be no guide. they won't let go. Yeah i released the white things on the sides and can pull on the CPU fan/heatsink and CPUs and try to move em off, but the guards or whatever they are seem to hold a firm grip on the board still.

I've sat down for about an hour wiggiling and looking, and I stopped. I stopped because I want to go get the sledge hammer from the garage. Is this the tool I'm missing?

Re: computer soon to blow up

first off, ive never heard of 2 individual p4's. how did you get that to work?

Re: computer soon to blow up

Beats me... Thats what was put into the system when it was constructed.

Computer specs state there are two operating p4's too.

Re: computer soon to blow up

You have a Pentium 4 HT. HT means Hyperthreading which means that it tricks the computer into thinking that you have two CPU cores whereas in reality, you have one. This is meant to help with multitasking. The most likely reason for your problems are to do with overheating. Your P4 gets very hot, which either causes crashes or causes it to throttle (Reduce the speed). To try and counter this, your fan goes absolutely bonkers which would be the banshee like screaming. Sounds like you need to either clean your fan, reseat it on the processor or purchase a new fan.

Re: computer soon to blow up

Is that so? i didn't know that HT would indicate that the computer has 2 (CPUs). Alright, thanks.

But regardless of my mistake, How the hell do I get the d@mn thing out so I can physically inspect it, and possibly replace it with a higher clocked p4.

Speaking of which, buying a 3.4 or higher p4 socket 478 cpu should bring a significant increase to performance from 2.8 ghz right?

Ok. I just hooked up my computer after cleaning out the heatsink and all the fans as well as blowing out as much dust as I could (no I didnt breath in deep and exhale lol). This is how I know it is not a fan issue.

a) while in the BIOS I glanced at the fans. they seemed to be operating normally, then again there was no screaming either. However, this was on boot up. While I was in BIOS, no screaming.

b) I've cleaned my fans and WD-40'd em a week ago. problem persists.

c) I can hear my fans running. The ringy screaming noise I am referring to is not a fan. No way. Its so high pitch and consistant, I can't see it being the fan. Not to mention, when I web browse and use the scroll wheel, it is like instantly transferred into noise. the moment I scroll down its screaming and as soon as i stop it stops. Would the fan not be delayed to an extent or something?

either way, thanks for the input. I still think it is something else though.

your mad....

are you sure its not your PSU (power supply unit) thats making the noise?

Re: computer soon to blow up

You WD-40'd your fans......... thats probably a bad idea..........

Re: computer soon to blow up

Compressed air would work much better than WD-40 lol , you can get it for a fiver on amazon.co.uk to be honest your PC sounds like it was made in hell and i have no idea where to start...

Re: computer soon to blow up

Bike chains and car engines use WD-40..... not processors....:laugh:

Re: computer soon to blow up

WD-40 isn't a lubricant.

" B) during a benchmark test, CPU FPs drove my CPU(s) mad and the noise returned"


'nuff said. Your CPU fan spun up, and you heard the whirring.


Now you need to flush it out with pressurised water (WD may stand for "Water-Displacement" but it takes two to tango, biatch!) and soap, then apply lithium grease.

Re: computer soon to blow up

WD40 simply prevents water from getting to the metal, thus preventing rusting. So your going to have a rust free processor that doesn't work!

And CPU's don't make noises, they have no working parts. I thought of one other possibility. Could very well be Coil Whine. This is where the electricity is at the resinating frequency of the transformer coil. It can be fixed by sticking a blob of blue tack on top of the coil where its coming from. This stops it from vibrating. Try it!

the lock ups are likely to be a coincident. Your computer probably has electronic aids (Thats viruses btw.)

Re: computer soon to blow up

sounds like its either a fan, or a PSU.

in the past I have stopped fans by slowing them down in the center with my finger to see if they are the ones making noise. only stop a fan for a few seconds if you try it.

you might try downloading SpeedFan to see what your computer temps are during all that noise, or check your bios for temps during those problems. system lockups and bad performance are common with high temps and cooling problems. As for upgrades, download CPUZ, run it and in the 'about' tab, save the results and post your specs back here. your 2.8ghz p4 is probably a northwood, and is probably overclockable to 3 - 3.2ghz.
