Hello everybody I have 2GB of ram and now it's suddenly not working and this is my story. Like usual day i sat down and was ready to use my computer but something happened and when i pressed start button my pc would automatically turn off after ~2 seconds. So i tried to solve the problem and found out this that my pc would boot when my ATX12V is plugged out. PC would boot but there was nothing on my screen. So I took out one stick of ram out of two and plugged in ATX12V wire and my pc would work. I haven't changed my sticks of ram i have used theese like for four years, but suddenly my pc would only boot one ram stick but not two. So how could i fix this problem and sorry for my english it's not perfect.
