My computer recently started rebooting randomly, or whenever there's a bit of shock on the table. I thought probably one of the slots are loose. And I found on my OS that my 8 x 2 = 16GB RAM was showing 8GB. I thought one of the memories has fried or something, so I pulled out to find out which one. It turns out it was both of them. Both of them got weirdly damaged.
When I pulled one out, the OS showed 4GB of memory. When it's placed back in, it shows 8GB.
What's this? Can a memory get damaged like this? - losing half it's size.
