I recently upgraded my PC to the following Spec:

• Processor: Intel Core i5-3470


• Motherboard: GA-B75M-D3H - GIGABYTE B75M-D3H IVY BRIDGE MOTHERBOARD


• RAM: JM1333KLN-4G - TRANSCEND 4GB JETRAM DDR3 1333 DIMM 9-9-9


• HDD: ST31000524AS - SEAGATE 1TB 3.5"HDD 7200RPM SATA 6GB/S 32MB CACHE


• Graphics Card: Using the onboard graphics

When installing Ubuntu 12.04, all the boxes shown on screen as well as the menu bar across the top are corrupted. It seems to be a 3d related issue because 2d items such as pictures display in the install window and/or icons are ok during the install.

I can upload pictures later but basically all the boxes look as if they have horizontal and vertical tears/pixelation. The edges which are supposed to have a nice shadow effect are also all choppy and jagged. Text on the boxes is barely visible and as the text updates different letters become partially visible.

It was a bit difficult but I managed to setup my Wi-Fi (for updates) and complete the install.

When booting the background image displays as does the mouse cursor but then the screen just flickers a few times before turning off completely.

Pressing Ctrl-Alt-F1 gets me to the terminal prompt and I was able to run:
$sudo apt-get update
$sudo apt-get upgrade

After installing 305 updates the issue was still not resolved.

Does anybody have any ideas??
I also tried the 12.10 daily build but the Kernel crashed during install

I'm new to Ubuntu but so far this is really disappointing, I was hoping to use this PC for some development projects I had in mind but it doesn't work out the box! I also don'thave unlimited bandwidth so I can't keep downloading updates all the time.

Windows 7 worked just fine....
