I was putting RAM into my sis's computer (ive put RAM in alot of computers) and I go to cut it back on and have it plugged in right and etc and made sure. .and when i hit the button. Nothing happens ...but when i plug the cord in the back a green light comes on on the motherboard. But yet nothing happens when i hit the button. (i also tried taking the new RAM back out and still doesnt work)

Whats the problem?

Thnx Is it the correct RAM ? ?
You may have inadvertantly dislodged something while inside the CASE...double check all connections.Check that the button on the FRONT has not BROKE i had the same problem on my pc at home i just took the front cover of got a pen and hit the button with that might help ya ! Well, the RAM is about the same "age" as the computer. I took it out of my custom built computer and was trying to give it to my sis b/c she needs more. I checked all the connections inside the computer and everything seems to be fine. Could I have shorted something out? I called a computer PLACE and they said to leave it unplugged for a few hours to let the motherboard "reset" and see if that works.

idk. ergh.The button worked fine like 5 seconds b4 i WENT in the computer. lol. but i will try that ..

thnxThe RAM being the same age as the computer really isn't helping...

We'd need to know the make and model of your motherboard in order to provide you with the correct memory...I have a similar issue...installed new memory, but my PSU blew when I turned the PC back on. Have purchased new PSU and all I have is the green light. I take it that my motherboard is a gonner?
