if you upgraded your existing pc with these parts then your WIN XP thinks its a new pc.
its because of the m/b
#2
does the mobo accept the cpu ???
check the specs for the mobo
#3
i think if you change more than 3 components windows XP doesn't like this and wants to to buy a new licence, so you need to re-install Windows again and all should be fine.
#4
try changing the CMOS Battery

its ur CMOS Battery dude!
I think it maybe flat!

or there inst one on board lol!

with a fresh install of XP after you installed the components?

Basiclly when windows installs it tags the CPU and Motherboard with a code.
If you replace either one Windows wont boot becuase it thinks its a new pc, because the code doesnt match.
But this has nothing to do with it if this is a new build, and not an upgrade.

Go check your CMOS battery, go on, shoo! lol

Ive took this one out, and put it back in.
But i dont have a spare. Can i take it out this pc im on now?
Or could i risk ******ing this up?
#12
when evre you do a new system build ie: new board cpu you should always do a fresh install of windows as the old version of windows will not know what the hell is going on not work, simple

it would be best to go get a new one tbh.
do you have another device that uses the same battery as the one in ur m/o?
maybe a torch or somthing?

try it in that and see if it is the battery thats dead.

I dont get what you pair on on about keep quoting this.
I would install windows xp. But i cannot get a display :S.
If i had a display i would be able too.
The hard disk is clean.
#16
When it tells you the CPU has changed can you not just press F1 to continue ?
Were all components of the PC new ?
#17
If you have no display, the problem is almost certainly with the hardware. Check RAM first, try booting with one piece at a time in. If this doesn't work, check graphics card. Try booting off onboard graphics if m/b has this. If both these fail, it could well be a m/b failure.

Edit - another thought, check that the CPU is properly seated. But, having read your original post and found out it's a second hand Asus m/b, my money would be on that! In my experience, they're not the most reliable boards around.
#18
are there any beeping nosies when you start up the pc?
#19
got this from the net..

It means the computer has failed to pick up automatically the CPU type and/or speed. This is checked by the BIOS and the message is probably due to an incorrect setting there (i.e the CPU speed has been set manually, or it is in "compatible mode" (i.e slow).

Try checking the settings and if that doesn't work, updating your BIOS. Some CPUs require a bios update even though the board supports them. Make sure you have the correct BIOS image for your motherboard - it's always safest to double-check on forums etc before flashing.

I don't understand, how it first booted up went to the startup screen and said cpu has changed, but now doesn't boot up at all :S?

I cannot change the cmos battery as i dont have a spare to hand.

How come it doesn't boot up now?
#21
When you try to power up the PC does it actually turn on (can you hear anything ?) and do you hear the single Beep ?

Yes it turns on.
I hear the fans etc.
It beeped the first time when i got display.
But now it does not beep.

sounds like a faulty mboard or psu at first glance :thumbsup:

I would try doing this. Make sure everything is seated properly, may be worthwhile taking out some of the components and reconnecting them.

I Read online that if you do not get a beep but the fans power up it normally indicates a CPU/Mobo problem.

just tried those.

Could it really be the cmos battery?

I'm starting to doubt it, considering it worked before hand
#26
no its nothing to do with the battery, it won't even be used with power to the machine
Did you confirm that the previous owner had updated the bios to work with this cpu or was compatible from the first release of this board?
ps the comment about asus boards?? switched to them 10 yrs ago, prob 200 boards later never had a faulty one

I'd have to ask the previous owner.
Can you update the bios with no display?

it may be possible in this case as the board did boot using the old cpu parameter but it's risky so only do so as last resort
first you need to try and get a display back, are you absolutely sure you had the cpu fan connected when you first booted? cos if not u may have fried the chip
first of all take anti-static precautions, earth your self on case (plugged in but switched off at socket, do not go near internal components without doing this

what video card and psu are you using?

To reset the cmos, remove all power cables from mainboard and remove cmos battery, leave for 30mins should do it
rare to take more, common to take a lot less.

BFG 8800GTS
and Coolermaster 520W Modular.

yes im 100% i had the cpu fan connected.

You think i should remove everything now, and remove all the cables?

Do you have msn? As it would be easier to communicate?
#30
it wouldnt make a difference if the cpu fan wasnt plugged as its a Q6600, if no fan it will auto shut down when it gets to a certain temp
banned#31
it was def plugged in.
anymore ideas?
#32
did u reset the cmos?, if that didn't work you're prob gonna have to confirm its bios 1103 and up will take that cpu, without that confirmed, its anybodies guess but very likely due to your initial error mesg

unf the shutdown does not always happen quick enough and the signal to psu may even corrupt so its very dependent on luck
but as he is absolutely sure it didn't happen it's not a prob.

see post 29,
the bold means if your bios is an earlier version than 1103 then the board does not support the correct details for that cpu so may not boot.
it is also possible that if the previous cpu was a higher voltage than the 6600 and u may have damaged this cpu, pretty rare but possible.

the previous cpu was this particular 6600.

how do you change this then? i.e. the bios?

will leave it for a while.

Ive done what you said, sitll no display.
Argh this is annoying, i still dont get how it worked, then it stopped :/

Likly because it had memorised the settings for the previous cpu and fired the current cpu at the same settings, which obviously where close enough to give you a few seconds of display before whatever happened
Given the current status it may be a little risky to continue?, are you sure you want to?.
Look for the bios chip on the board it should have a sticker on it stating version number it shipped with and makers name ie ami or phoenix. then contact the person you bought it off see if they have ever updated it and what cpu were they running on it.

Yes i want to get this thing working.

Ive found the bios chip, but there is no sticker on it.

On there there is a sticker, but on my one, there is not.
