MSI Mega 651 - Not booting - Long beep (pause) long beep

Does anyone know what this post error is?

I have:
MSI MEGA 651 Barebone
Intel Pentium 4 2.8B GHz 533FSB S478 Retail Full Package
Samsung PC2700 333Mhz DDR 512MB 64X64
WESTERN DIGITAL 160GB 7200RPM EIDE HARD DRIVE MODEL# WD1600BB

Which I think should work (in theory. However when I try to power the
system on I get a long beep a pause and then another long beep. To
narrow the problem down, I've disconencted the DVD, and HD - same
problem.

I'm assuming it might be the memory becuase when I remove the memory
and just power on with the processor I get the same beeping. When I
remove the processor I get nothing (as expected).

I think the chipset on the system board is an SiS 651. If the memory
is a problem, What memory should I be using with this system?

Thanks for any help!

= not properly seated ram. With my board you really have to push the stick
in hard along its length to seat it properly.

 

njohn,

Did you ever find a solution to your problem? I am having the same problem. I think I might have pushed down too hard on the motherboard and might have a hair line crack somewhere.

If you found a solution please let me know before I purchase a replacement.

Thanks.
