hi all,

i decided to change my pc tower as i have done many times without issue - until now!

when i had re-built it eveything powered up fine , but no signal on the monitor and repeated short beeps
all the fans come on , hdd, cpu etc...... and the blue power light comes on

the monitor works fine with my laptop

i replaced the power supply - no beeps
took the ram out - repeated long beeps
put on stick in at a time - beeping stopped
replaced the graphics card - no beeps
replaced the mobo battery too

i'm really stuck if anyone could help it would be great

american trend bios (i think)
g8-sli mobo
pentium d
2 gig ram
512 ge-force card
500w power supply

Continuous Beeping: Memory or video problem
Explanation: The system is producing constant beeping in no specific pattern, or a fast "ringing" sound.
Diagnosis: This is usually caused by a problem with the system memory, or possibly the video card. The memory is more likely--the system complains long and loud if it can't find any usable memory, as there is no way to even start the boot process when this is the case. The motherboard itself could also be the problem.

Explanation: The video card appears to have failed. The PC may be refusing to boot up and the video card is suspected as the cause of the problem, or there may be an unusual error condition that implicates the video subsystem.
Diagnosis: There are many possible causes for a video card failure. Actual failure of the card itself is relatively rare but does happen. More often, the problem is due to misconfiguration or resource conflicts.
If you have a pci video card make sure is tightly and completely inserted into its slot. Try powering down, removing and reinserting the card and then rebooting.
On older video cards, you may have a problem with "chip creep" on the card itself. If there are any chips on the card that are in sockets, gently but firmly press them into the socket. You may find that they had worked themselves loose and that this solves the problem.

If you have added a video card to a PC that originally had an integrated video card on the mainboard you must disable this integrated video via a BIOS setting or motherboard jumper before adding the new video card. Otherwise, they will conflict with each other and neither will work.
If possible, try the video card in another PC. If it works there, then the video card itself is probably not the problem, but configuration or a resource conflict is implicated. Of course, if the card doesn't work in another PC, there is a good chance it is bad (assuming it is jumpered properly).

hi thanks for the speedy reply !

the set up is the same as before , i've re-set the bios and still no joy ?

i think i may have to buy a new cpu then mobo as they are the only things i have yet to re-place , is their anyway i can check if the cpu or the mobo is dead ?
people have said that if you don't get a beep on power up then the mobo is dead , yet when i take the ram out it beeps the ram error code - repeated long beep

It could be damaged motherboard,video,etc try the link on how to test:

ahave a read of these links i am sure they will help?

try clearing BIOS.

Please look at this link and try some of the solutions.Link
Check all the connections and make sure their hooked up. If possible try using different RAM. Also check the video card is in the slot correctly and if needed check that the additional power cables are hooked up.

hi all,

beep update !!!

took out the ram - long beeps repeating , award bios states - ram error so that would make sense
insert 1 ram stick at a time - no beeps
just bought a new stick and still nothing
when i powered on the pc as before all the lights, fans came on. I opened the dvd drive to make sure
power was getting to it then the drive started opening and closing then the pc shut down ?
so far i have replaced the - psu - pcie card
this is really bugging me now !! i took a look at the cpu and it looked ok
do you think the mobo is goosed ?
also how do i reset the bios when i can't get a signal ? i have replaced the cmos battery and has a fiddle with the jumpers on the mobo but still nothing ?

i've stripped it down again ! and tried every possible combination i can think of , here are the beep errors again, sorry for repeating myself.

re-bulit pc
short repeated beeps - error code - psu
replaced psu - no beeps
powered on with just cpu and fan, long repeated beeps - error code - ram
inserted old ram - no beeps
replaced ram with new ram - no beeps
replaced graphics card - no beeps
replaced cmos battery - still no beeps
signal is still dead ..............................................

any ideas would be great before i spend anymore money.

thanks in advance
