hi.........yikes here is another problem

okay so i got this pc. all was working fine i used it
sucessfully for around 8 months. the main problem i felt
i had with this system was the extreme noise that came
from the components.

okay me being me i decided yesterday to open it up
and replace the cpu fan because i knew this was faulty.
so i took off the cpu fan and took out the cpu (amd1600)
after this i tried to put the new low noise fan on. but
to my disspointment it just would not fit. the only way to fit
it was to remove the PSU wich i didnt want to do.

so all i did was put back in the original cpu and cpu fan.


i thought ill turn on the pc and what happened? nothing
nothing happened. when i turn my pc on there is no screen
no bios. I can hear the harddrive and CD Drives.
I did notice one thing that my geforce card's fan was NOT
spinning. but i dont know if its supposed to anyway.
i did put in another video card and the same happened
there is no bios no screen is appearing its just a black
screen with a yellow light on the monitor

Can anyone suggest anything that could have happened?
i have got another system. but just terrified of opening this up to test components.
Why wont bios appear what can
anyone suggest? what kind of tests can i do before digging deep
in my pockets?


from a rather upset and angry avid pc fan!


thank u
 
Well i am RMA'ing an Abit KV7 on monday because the screen is just black - worked for about the first 7 times flawlessly. Is my Nans system.

What i did find is that if you pull the "all clear" (CCMOS1) jumper, you are able to get into bios but then when you save and exit the screen goes black and you have to pull the jumper etc etc its an endless loop.

By the sounds of it (imo) your AGP slot is not provising power to your card - is it seated ok? I have not come across a graphics card that has a fan that is not meant to spin. So that, i assume, is where the problem lies.

Make sure the board post's - well i dont know if it will without a card maybe someone else could verify this... does it go "BEEP" when you turn it on?

If everything is plugged in good and you still get nothing i assume it is the motherboard.

Lets hear some other opinions on this.

p.s you may want to delete the other identical post to save on confusion.

Sounds like your processor is nackered. If it isnt that, something else is nackered, either way i bet somethings nackered.

The best way to find out what though is to eliminate things 1 by 1.

E.G :

Try the processor in another computer, if the processor works, try your graphics card on another computer, if the graphics card works, try your memory/ram on another computer, if your memory/ram works try your Hard drive on another compueter, if your hard drive works its probably the mother board :( .

Sorry for going on abit, but i didnt know how else to explain.

I figured that BIOS would give you a "CPU CHECKSUM ERROR" if the processor was shagged and if the memory had problems then you would get a series of "BEEEP BEEEP" or similar because the motherboard would not be able to post. If the hard drive and other drives go as normal this suggests to me that the CPU and RAM are fine and that the AGP slot must me the main cause for concern.
 
just try reseating the cpu, you won't have put it back in properly, failing that reaseat all componants as you may have knocked one of them.

it usually will chris, but still worth reseating.

the fan on the graphics card won't necessarilly kick in straight away. and no a machine won't post if there's a prob with the graphics card.

it'll just be something loose.
 
sorry for posting two forms i pressed enter by accident on one of them. i coulndt find how to delete it so im going to leave it to the administrators to delete it.

i havent tred anything yet. but im sure to say that if my graphics card does not power up and the other did not work its got to be something to do with the motherboard. im sure that the cpu is not needed to power up the agp slot?

im still unsure. i dont know wat i want the problem to be. first ill reseat everything. then i will try the graphics card in antoher system. what im scared of is takin that cpu and puttin it into this one. thats too risky so i dont want to be forced to do this!

thanks for ur help folkes
 
further to this

just wondering what the beeps mean? because either i cant get the rite jumper settings or there is no beeps. because i dont hear any beeps when i turn the system on.
 
Haha, Chris, your post was e-mailed to me anyway :D

It was 7.54am actually, I had to do a little work today, loudspeaker line fault problem on a school's tannoy system. I back now, KFC for lunch... ;)

And now we return you to our normal programming.....
 
haha the reason i deleted it was because i noticed after posting it was 7:54

Then i though "OH man! should have just edited it"...

but yeah...thats early!

mmmmmmmmm KFC
 
thanks u my old muckers!
just sorted the problem out. Techy you might be a Manc but me you are a G!:)

i reseated everything individually memory, pci cards, graphics card. i then had a look at ide cable. before the last dreaded CPU. I took off the fan and took out the cpu, put some grease on it and reseated it. Put the fan back on. Started the pc and hey it works now

but still my ti4200 gf4's fan does not spin!!!

thanks for your help
 
Good news psd99 :)

You best be looking for a replacement fan for your vid card, it's probably packed up, and it's there for a reason. A pain, I know, but best replace it.

I wouldn't know where to get one however, one of the UK overclocking sites may be able to offer you something.
 
glad it's sorted psd99!

in regards to the gpu fan, try cleaning it out, if it still doesn't work then you'll be able to get hold of some sort of cooling solution. although i don't think that a fan is necessary on this card. (just for show)

James
 
thanks once again!

what do u mean? u think my graphics card fan is just there for show? surely not. because its got to be there to cool the card down should it get heated?

im sure that if i look deep in my pc i should find some sort of gainward software that can speed up or slow down this fan speed. with regards to replacing it i know this mite sound silly but i did open this once a long time ago and beleive me its a SWINE to put the fan's screws back on! it mite not be the fan too i was thinking it could be a part on the actual card!
 
psd99: Thinking about it, Techy's probably right, that card won't need a lot of cooling. What is meant by 'for show' as regards the fan, is yes, it will cool, but it's probably not needed and was maybe fitted just to make the card more appealing.

As for the card being faulty, that's extremely doubtful, as the voltage required to drive the fan will be taken from one of the voltage rails on the card to make the whole thing work. The only instance where a vid card would work and a good fan would not work, is if you had a dry solder joint on the fan power connector mounted on the card. Which is unlikely.

And as for cleaning fans to get them working again, imo that's a false economy. Once a fan packs up, imo it's best to bin it. You may get a little more mileage out of it but sooner or later, probably sooner, it will fail again, which may lead to damage costing more than the price of a fan. I'm talking generally here, not just about your video card fan.

I'd suggest running the card, playing a game or something for half an hour or so, then touch the vid card heatsink. If it's too hot to leave your finger on there, get a fan. If it's berable to touch and just warm, it doesn't need a fan. Feel the temperature then judge for yourself whether it needs extra cooling or not.

Would you do the same on your car if the radiator fan packed up? Ever boiled over in a traffic jam on a hot summer's day? Same sort of thing.

Again, the proviso, 'in my opinion.'
 
NEVER buy a Vid card with a fan ... they are NOT needed if the manufacturer fitted a decent heatsync and they fail after a short period of time.

:D

Well, I'm sorry, but I'd have to disagree with you there, Sir Mucks.

In my experience if a fan's fitted it's usually there for good reason. And I've never had a vid card fan pack up on me. Yet.

My 9800 Pro is fitted with an arctic VGA cooler which managed to drop temps by 18C. Kind of vital should you wish to overclcock it, not that I overclcok either of mine.My other 9800 Pro has stock cooler/fan fitted, it gets a lot hotter than the one with the custom cooler.

Never buy a vid card with a fan? Hmm, that would limit you to lower end cards then...

So...Ummm... GeForce4 MX series and uh...FX5200 then...

even my previous video card needed a fan - 2 in fact! and a MASSIVE sink!
see a pic of it here

its a 128Mb GeForce4 TI4800td My Vivo by the way - Leadtek A280td series. way out of date now lol

Well mucks you saying that an X800XT doesnt need a fan? i'd say that the manufacturers put fans on cards for a reason. You will note that they do not use them on the lower performance cards because they are not needed yet

if they use them to make the cards more appealing then surely they would just bung one on all of the cards they manufature???

just a though

hmm...

chris
 
Sorry to burst your bubbles gents ... no video card "needs" a fan ... but don't they look great. ;)

An Intel DX4/100 CPU didn't even need a heatsync and early models never came with HSF. :eek:

However, If I were a manufacturer and needed to cut down on the "size of the heatsysc" then a fan would help, shame the reliability on some of these "fans" are rubbish.

See pic ... Sapphire Radeon 9600XT
