I've recently installed Ubuntu 12.04 on my laptop, and every time i tried to update it, it would freeze for a few seconds, and tell me that the updates could not be downloaded. After many, many tries I managed to get them downloaded, but then in the middle of installing them, it froze. Completely. No mouse movement, no blinking lights, no nothing. After a few hours of letting it sit there, I finally hit the power button to do a hard reset, and now when I select Ubuntu on the boot screen (Dual-boot with Windows 7), I get a blank purple screen, and then nothing. Another freeze. I've tried getting into the console, but no command I input has any visible effect. I have a ton of music stored on the partition it's in, so I'd really rather not have to reinstall.

My specs, to the best of my knowledge:

Clevo Corp model B7130 (Sager custom)

CPU: Intel Core i5 @ 2.53gHz (4 CPUs)

Graphics Card: Nvidia GeForce 425m

4096 MB RAM

Drivers: Whatever comes with the download of 12.04.

As a side-note, I installed Ubuntu via the Windows Installer program (wubi). Does that make a difference?
