Ram problem at startup

Hey,

i took a 1gb ddr2 ram stick out of my other computer and tried to put into my computer i have for testing purposes.When putting it back where i got it from, the computer will not boot up, it has one long beep, which I'm pretty sure is a problem with the ram, which would make sense.I have tried moving it around different slots, and even cleared the CMOS which just changed it to having 2 shorter beeps instead, im a bit out of ideas now, so any help would be greatly appreciated. Also the motherboard is a Acer MS – 7284 VER 1:1 if that helps.

Thanks.

 

Go to this link and choose which Bios your Motherboard is using... this should define the problem..

Thanks, how do you happen to check what BIOS i am using? just to make sure

 

Just go to this link and download its a freeby and this will tell you your Bios, give it time to load when first starting .
