    Hello and welcome to Techspot.

    When you inserted the new cpu, did you use thermal paste?

    Is the heatsink properly attached, and the right way round?

    Have you tried clearing your cmos?

    Does your mobo support the new cpu? Check in your mobo manual.

    What mobo do you have?

    Regards Howard :wave: :wave:

    I would say that thye motherboard can't run the 1800+ because that is
    quite a big leap from a 900MHz Duron.

    ID the motherboard and visit it's manufacturer's site for a manual that will tell you which processors the board can run.

    XP 1800+

    QuantiSpeed™ architecture
    266MHz front-side bus
    462-pin Socket A interface
    128K on-chip L1 cache
    256K exclusive on-chip L2 cache
    Fully pipelined superscalar floating point engine
    3DNow!™ Professional technology and superscalar MMX™ technology
    0.18-micron manufacturing process
    1.75V core voltage
    37.5 million transistors
    128mm^2 die size

    "Besides the hardware changes, you've obviously noticed that AMD has slightly changed the name of its flagship processors. The new Palomino processors are denoted by the new "XP" designation. Unlike previous 7th generation processors, the Athlon XP processors are branded based on their performance relative to conventional Athlon processors. So in the case of the Athlon XP 1800+ we're testing today, the chip offers similar performance as AMD's previous Athlon product at 1.8GHz even though it's only running at 1.53GHz."

    Here are the specs for the Duron 1000

    200MHz front-side bus
    462-pin Socket A interface
    Large 128K on-chip L1 cache
    High-performance 64K exclusive on-chip L2 cache with hardware data prefetch
    Fully pipelined superscalar floating point engine
    3DNow!™ Professional technology and superscalar MMX™ technology for great multimedia performance
    0.18-micron manufacturing process
    1.75V core voltage
    25.18 million transistors
    106mm^2 die size

    The FSB is 200MHz for the Duron and 266MHz for the XP 1800+, so if you can't set the FSB to 266 on your board, you won't be able to run the 1800+ at full speed even if you got it to work at an underclocked speed.

    i know this board supports the cpu, but no overclocking is possible.

    all good now

    got cpu tested, dead as the proverbial doornail! Beware ebay sold as seen! replaced the cpu at my local comp store with a used athlon 2200+xp everything ok. had to take a stick of ram out of the board to stabilise it now every thing ok. Thanx!

    Yes, ebay and computer parts don't really mix.

    Yeah...I had the K7S5A for 3 years. It was not the best by any stretch, but it was ok. I had a Athlon 2000XP

    This is simply not true... I have built three systems using almost nothing but parts from ebay!

    As with anybody or anywhere you're buying from you need to have common sense when you buy. If you buy a product from a non-reputable seller with low feedback, or your case, you bought an "as-is" CPU, what do you expect?

    i couldn't really be bothered turning off Far Cry on my slow computer to bring back the 2200+ i paid £10.00 for! If you have a faster mobo and cpu for £10.00 let me know!
