Upgrade failure!! any ideas?

Hail mighty geeks,

Need some expert help. I recently bought a new motherboard (Asrock ALiveNF6G-DVI) and a new AMD CPU (AM2 Athlon 64 5200 dual core X2), plus a sync pair of 1gb DDR2 667 DIMMs, plus a new graphics card and other bits.
Problem is, after fitting the CPU and installing motherboard, PC starts to boot, fans spin up and hard drive engages but then it just does nothing. No output from onboard graphics or graphics card, no warning beep, fans continue to spin but no other reaction.
Im fairly sure this is a fitting error with the CPU but ive taken it out and put it back, to no avail. Even if I strip out all except the MB, memory and CPU it still fails to boot past fan spinning.
I took the CPU back to the shop and swapped it, but it still fails at the same point.
Im running Win XP pro, with a 650watt power supply.
Is the MB broken or is there something wrong with my set up?
Cheers for any help

 

No beep or series of beeps at all?
Your system is not passing POST, but you should be hearing a series of error beep codes!
Have you checked that you have connected the internal speaker correctly as per the mobo manual?
You say that your ram modules are in 'sync'. Im guessing this to mean that they are identical modules....but are you sure they are compatible with your mobo requirements?
Did you take measures to prevent ESD (static elect) discharge during installation?

Just a few thoughts!

Regards...

 

If the fans stay on it is unlikely that your processor is bust.
have you tied the OLD graphics card just to get things going?
What sort of new graphics card have you and have you connected any auxiliary power correctly?

Thanks for the replies.
I took the MB back to the shop as well and swapped it for an ECS RS485M, and its still goes zombie, fans spinning but nothing else happens..... this is despite the cpu and MB being changed. Using the old graphics card had no effect.
Ive had to reinstall the old MB with old CPU, old mem, but new graphics card and new SATAII hard drive (ghosted from old IDE drive), which works fine. Basically either the new power pack or new memory is causing the problem, or its some kind of incompatibility - but all the parts are specced to work together.
Any ideas???

 

Run memtest86+ to test your memory. http://www.majorgeeks.com/Memtest86_d4226.html

 

Hi would run memtest, but unfortunately the new MB thats failing takes DDRII, old takes DDR I
as far as Im aware you cant use either in the wrong MB, even if its for testing - ?

 

Hi James......I would say its a case of incompatable memory!

double check your compatability with your new motherboard, as some mobo's can be very fussy in this particular area.

Still, you should be getting a series of error code beeps upon power-up!
