RAM problemo

I'm not sure if this has been discussed before but I was trying to put some new RAM in to my new computer from an old computer (2 sticks of 256mb each at 333mhz. The problem was when I turned on the computer the monitor and the mouse did not work.

 

so it means it didnt work r u sure ure pc can handle ddr instead of ddr2?

 

If the monitor wasn't working how do you know the mouse isn't working? lol

 

i have a colored mouse.

 

And i have with this computer DDR2-SDRAM

 

hum.... fitting ddr ram on a ddr2 slot...interesting/stupid
