He mentioned a "colorful pattern." Can you describe it? – Chuck R Nov 28 '13 at 3:26
@AvinashRaj is not a dupe, see answer above. Close Voters no answer there will solve OP's problem. – Braiam Nov 29 '13 at 2:13

Two possible causes of your problem:

  1. Your Nvidia GeForce 6150 SE nForce 430 graphics card is going bad. This would explain why everything related to graphics is causing your system to freeze. A bad graphics card is a common cause of this problem.

  2. You don't have the minimum system requirements necessary for installing Ubuntu 12.04. This is less likely in my opinion, because Ubuntu 12.04 only requires 384MB RAM. However the Nvidia GeForce 6150 SE nForce 430 graphics card shares up to 256MB of your system RAM, so that would increase your minimum system requirement for RAM up to 640MB. If that is your problem, then you would need to install a more lightweight *buntu version such as Lubuntu 13.10, which somewhat resembles Windows XP in look and feel.

If the same happens with Mint, I am 200% sure that is a hardware problem. – Braiam Nov 29 '13 at 1:53

I suspect this can also be a memory problem. Do a test to the memory with grub. I had some problems like this one on older computers. In some cases it was also the motherboard.
