I recently installed Ubuntu 12.04 on my Sony Viao vpceb3e1e. Everything works fine till I reach a certain amount of memory, then all the apps crash. I found out it was due to faulty RAM. I used Memtest86+ to figure out the problem and only 1 of my RAM sticks is broken. I'm now only using the non-broken one.
Since I installed Ubuntu with the faulty RAM to start off with (I'm 100% sure it was broken when I installed it since it was a recurring issue for 6 months), should I do a full reinstall?
Or, is there a way to check the consistency of my system to see if there have been errors written to the disk? and a fix?
