    My computer:

    Thermaltake 430W PSU
    Chaintech 7NIF2
    Athlon XP 2400
    2 x 256 pc2100
    80GB Western Digital
    ATI Radeon 9800 Pro

    Situation:

    I just replaced the chipset cooler with a Zalman NB47J and when I assembled the computer back together, I just got a 4 second beep that repeats and the monitor was blank. No BIOS screen or anything.

    Heres what Ive tried so far:

    *I thought it was because of a misconfiguration of the front panel connector, so I looked up the manual and put the cables as they should be. I tried various configurations with no luck.

    *I tried clearing the CMOS and also taking out the battery.

    *I disconnected/removed any cards or disks, just leaving the motherboard, fans, and memory.

    *I tried booting with each ram stick individually and also put them in opposite slots.

    *I connected the monitor to the integrated graphics instead of my ATI card.

    My dad thinks its possibly fault of the Zalman heatsink. Should I try putting back the previous cooler?

    Any other suggestions?

    P.S. I dont think the PSU is at fault. Its fairly new and should provide enough power.

    what type of bios does it have?
    phoenix? award? ami?
    if you know what type of bios it has you can search for for example phoenix beep codes in to google and find out what the beeps mean.

    make sure the cooler is seated properly. but also make sure to find out or remember what bios type is to so you can search for the beep codes.

    normaly if you have tryed with the minimum stuff needed to boot then its eiether the motherboard or PSU.

    The BIOS is Phoenix-Award. I dont know where to find the beep codes for it though; I usually just see Phoenix or Award.

    WSFuser this is what I found:

    - one long and three short beep = video card fault
    - long repeated beep = memory fault
    - short repeated beep = PSU or mainboard fault
    - continuous low and high beep = CPU overheating

    Hope it helps

    Try no mouse or USB etc except video. It's a longshot try blowing,blasting some air into the RAM sockets. On dusty or not motherboards it's prevented the RAM making a good connect failing to post.

    Pull out all the memory and m/b cables and power it on. Does it continously beep if you do?

    It wont be the PSU as it beeping.

    It might be the motherboard...I hope not

    @WSFuser

    Any luck ?

    Go by the AWARD BIOS codes for Phoenix-Award.


    Times like this those POST Diagnostic cards come in pretty handy.

    No luck but I found a mobo/cpu special at Fry's.

    I hope I dont screw that mobo up :doubt:

    Hello,
    Double check the seating of the components, particularly CPU and video card. This happens often when these components are not seated right.

    Agreed! I have a desktop at work that is VERY fussy about the video card position. When it's good, all is right with the world. When it's not, the PC refuses to boot...

    Ive reseated the components various times but its not important anymore.

    Ive successfully installed the new mobo and CPU :thumb:

    I wonder if this is a manufacturing defect? If a particular circuit pathway was not properly soldered on the circuit board, how would you be able to see it other than trying to power it on and running tests? The main question is if the manufacturing plant tested the item?

    Yes HAN good point. I have also found the back end of the graphics card is not pushed very firmly down it fail to POST. Certain cases make this problem worse. I was going to suggest trying the components out of the case, but you no need now. About the time of AGP graphic cards, companies sent out Pc's in mail and customers found there Pc wouldn't turn on. It was because of this same problem. The cards had lifted out in transit which they remedied now by fitting plastic hook that hangs off the PCI-E slot to hold it in place.

    It seems Frys is a great place for bargains.
