Solve : Plz Help ! CPU or MOBO broke ??

1.	Solve : Plz Help ! CPU or MOBO broke ??
Answer» Thanks for reading ..Im at my wits end with this lot so ANY help/advice would be great. Ok from the start .... I had a system running a Athlon XP 2800, and one day I turned it on and nothing, FANS turned on for a split second and then turned off again! I tested every piece of equipent and was left with the thought process of the Mobo or CPU being broke.. So I got myself another Socket A Mobo (GIGABYTE 7VT600-RZ) plugged everything back in and the same thing happened again ..fans on for a split second and then off again, So after this I thought ok it must be the CPU then... So after much begging to the missus I got myself a new Athlon XP 3200+ from Ebay, the new CPU finally arrived (had a few probs with seller) plugged everything back in and would you beleive it still Nothing !! the same thing is still happening ... Could I be so unlucky to get another Faulty CPU ? (the 3200+) I have tried every single other item I can PSU, MEMORY, Graphics Card etc and ALL of them work fine in a old pentium comp I had around. Ive checked for compatabilty probs with the new motherboard and cant find any fault there. The only time I can manage to get some power running through the new & old motherboard is when the CPU isnt inserted fans turn on & light up etc, but of course it wont boot up like that ... so that makes me think the Mobo is ok and Ive just been unlucky enough to buy a dud CPU becuase as soon as I put it back into the mobo ..nothing as usual happens. any ideas ? Thanks, Dan. Although it works fine in your old (less demanding) computer the PSU could still be the problem. Quote When the computer is powered on, the internal power supply initializes. The power supply doesn't immediately provide power to the REST of the computer. First, it determines whether it can supply the proper voltages that the computer's components REQUIRE. The power supply sends out a POWER GOOD signal when it determines that it can supply reliable power to the rest of the computer. When the CHIPSET receives this signal, it issues a SYSTEM RESET signal to the processor.

To be Honest though, Im already £150 down on the new Motherboard & CPU ...and I cant justify spending another £40 on a new PSU unless I can be more sure .... and although the 'less demanding sytem' is older ( 2Ghz P3 ) its not that old really Is there anything else that could be causing these symptoms ? ..It it possible for a Faulty/Dead CPU to cause a totally dead system and somehow stop the power going through ?dancryer .....Quote Although it works fine in your old (less demanding) computer the PSU could still be the problem.
