Ubuntu 12.04 freezes after boot

**tbrann** · January 7th, 2013

After installing Ubuntu 12.04 from a CD on to my Toshiba Satellite laptop, there was a message from the tool menu that I needed to install upgrades. So I did, then restarted the computer as directed, and now it freezes when the desktop comes up and neither the mouse nor the keyboard will work. I have to do a hard reboot.

I tried to reinstall from the CD, but it stops during installation. I tried to just run the OS from the CD, but it still freezes.

System info:
TOSHIBA Satellite C655D
Processor:AMD E-300 APU with Radeon HD Graphics 1.3GHz 2 Core(s), 2 Logical Processors
Display: AMD Radeon HD 6310 Graphics
RAM: 2.00 GB

I apologize for the repetition, this was previously posted under the wrong prefix and I could not find a way to correct it.

The CD installed the 32 bit version.

check the cd for possible errors at the boot menu!
In which part of the installation prosses the crash happens?

OK I inserted the disk and clicked the option to

check the disk for errors
No errors found.

The problem is in the laptop, not the CD

When I tried to install, it let me select a language (English) . Then the CD drive started whirring & shifting as if it were installing. Then it just froze at the screen that says ubuntu with the five orange dots underneath.

maybe there is a problem with the cd drive. Do you have a usb drive , Can you make a Live Usb drive system with another pc?

I don't think the problem is the CD drive. As I said, the first installation went fine and I was able to get on the internet etc. Then
I doI downloaded all the updates as instructed & restarted to install them. That's when the problem started. There is something that got downloaded that is messing things up. A bad driver, maybe.

Similar problems happened to me last summer when I got Ubuntu from the internet and downloaded it onto a partition. Things froze up then too.

At that time I had Windows 7 on the other partition. Eventually I had some type of disk error that couldn't be fixed, so I replaced the hard drive and installed Ubuntu fresh from a CD, with no partitioning.
