I've upgraded it over the years (bought new 16gb memory, new ssd). Now I realized it's too slow for me, and decided to upgrade CPU.
I've found a configuration with better cpu https://www.amazon.com/Acer-Aspire-V3-771G-9809-17-3-Inch-Laptop/dp/B009JXJWZI to ensure compatibility and bought its cpu from the local craigslist.
Now I experience random segfaults (programs crash, system wouldn't boot sometimes). If I have only one RAM (normally it's two of them), segfaults starting to occur less frequently (at least I can boot).
I have Linux Mint 18.1, with 4.4.0 kernel.
Anything I can do about it?
