I hope this is the correct forum for this question. My daughter has an Acer Aspire 5 and I wanted to add some memory to it. I searched on the Crucial website to find out which memory sticks to use and ordered 2 8GB. I popped out the two 4GB sticks and put in the new ones, put everything back together, and started it up. Everything comes on - the keyboard is lit up, I hear the fan, everything seems normal except the screen is just black. I took the new memory out and put the original back in and same thing - black screen. What should I do? Has this happened to anyone else?
