Emachines w6409 will not accept 2 1 GB memory sticks. One stick at a time will work fine and both sticks show as good when used seperately in either slot, but when I add the second stick, the computer will not come up when started. The memory is the right type, and the motherboard is supposed to be able to handle up to 2 GB of memory.

I had/have same machine and when I bought it, I read book frnt to back, and all over, its only expandable to 1gb ram. I know it haas four slots but when I consumer reports.com'd it back in the day that was the 1 low mark it got, only expandable to 1gb. might wanna buy smaller compatible sticks. GOOD LUCK! Great machine bought mine Jan 05 never had a problem that I didn't cause! I'm not giiving up on mine yet, got new one other day as an impulse buy, I do miss a lot about my emachine!

try removing the cmos battery and put it again and booting up.. since you have bought same kind of ram i dont think it could be a problem.also check for the jumpers in *********** board where you can reset your bios. be sure to read *********** boards manual before this

SOURCE: which slot to place one memory stick in to boot using only one stick of ram? Emachines T2341

slot one if it does not boot up then use the next slot slot two make sure you have the right memory for the machine

SOURCE: I have an emachines W6409.

My guess would be that one of the components can not support 2GB's of RAM. Did you try both sticks of RAM one at a time?
