Your motherboard is probably not designed for the ddr modules.  Which motherboard do you have?

can you give us more information??  I'm assuming you had a board that has slots for BOTH PC133-SDRAM and DDR-RAM, is this correct?  If so, did you remove the SDRAM as well?

If you've tried putting DDR into a board designed for SDRAM, with no DDR slots, then it won't boot.

More information would be good:  Make/Model of motherboard.  Make / Speed of DDR purchased, type of beep codes, etc.

What is the make and model of your motherboard, tradavkar??  Also, thanks for letting me know what size the RAM is, but I need to know the make and the speed ie: PC2100, PC2700, etc.  Please let me know.

Here's some things you should know:  

1st, if you had PC133 RAM, and your cpu runs at 133MHz FSB (check your bios to see) then the PC1800 RAM you're using isn't actually fast enough product for your system, you need minimum PC2100 so it can run at 133 / 266MHz.  What you have is designed to run 100 / 200MHz.

2nd, it would really help to know the make/model of your motherboard.  You can probably see it screened on the board itself, or you can use a utility like aida32 to tell you.
