I had ubuntu 15.04 installed but its support ends at january and i dont have that much bandwidth and money to do a upgrade every 9 months so i turned back to 14.04 upgraded it to 14.04.3 but i have a problem now before my machine recognized 5.7 GB of ram but now it sees 5.2 GB of ram i ran a memtest for 30 minutes pass 1 with 0 errors but why is this sudden decrease in recognized memory should i be alarmed ?
