I use a HP Pavilion dv6500, and I recently upgraded my ram on my laptop from 1G to 4G, but I keep getting random issues. Here are a few:
- When watching youtube videos / vlc videos after a long period of time, the whole system will crash and kernel panic (I can't CTRL+ALT+F1 to a new terminal, Caps lock light flashing)
- Firefox will crash randomly
- Compiz has "crashed" once or twice, not sure if related.
- Nautilus has crashed
- NetworkManager no longer saves my wifi password (possibly unrelated)
I thought it might be my memory controller, so I did an
lshw and found that there was an nVidia memory controller that was unclaimed. It's called
MCP67 Memory Controller. After a google search, I found a link to a similar problem on Gentoo.
So I went into the BIOS and did a Memory Test, but it passed. On the article above, it talks about adjusting DRAM timings, but my BIOS doesn't have such a feature.
Is this typical for a quick-and-dirty RAM upgrade? Should I reinstall ubuntu / would that help? Any advice would be greatly appreciated. Thank you!
