I tried to upgrade my RAM memory, but when I opened the computer and tried to put them in I realized that I have ddr2, and I bought ddr3. Well, nvm, I will exchange them, but here is the problem. When I put my old memory back into my computer and tied to turn it on, I just hear strange beeps and nothing is happening on the screen.

What I tried so far: changing my 2 old RAM sticks over every slot; unplug all power and wires and try again; unplug all power and wires and remove RAM and remove battery from motherboard for a few minutes and pressing power button few times and than put back battery and try again; I blow the dust from RAM sticks and from motherboard; and I checked if my motherboard is burned. I also tried to put sticks inside by pressing left side first and than right one,and opposite, and pressing in a same time both sides.

I don't know what else to do.

Did you handle the memory the proper way? –  Ramhound Oct 1 '13 at 14:13
As a side note -- before you exchange the RAM use a tool such as this system scanner to find out exactly what type of RAM your system will take. You also don't want to buy the wrong speed, etc. –  Neil Neyman Oct 1 '13 at 14:29
Do the RAM stick smell burned? Are you sure you are inserting them all the way in? Do they click into place? –  terdon Oct 1 '13 at 15:13

Sounds like the RAM is not correctly in the slots or the RAM has been damaged when you have moved or taken them out. Try with just 1 stick at a time (If you have more than one)

If not all the sticks may be broken in which case you will have to buy more.

Cool. That should fix the problem you are having :). –  Ash M Oct 1 '13 at 15:56
Or maybe the motherboard? That seems like it would almost be more likely than both ram sticks going bad. @user2834926 –  Neil Neyman Oct 1 '13 at 17:56
