[ubuntu] Colored stripes at the end of install

view story

http://ubuntuforums.org – Hello there! I'm absolutely new to Linux (former Apple fan), and I'm here because I'm unable de complete the installation of 12.04 on my new PC... So here I am, asking for a little guidance please! ;) It all goes well until the very first reboot, and then instead of a regular desktop display, I get weird looking multicolor stripes, and nothing moves... Here's what's inside the PC in question: - Motherboard: Gigabyte GA-Z77-D3H - CPU: intel Core I5 - Graphics card: NVIDIA GeForce GTX 560 Ti Do you guys think I'll be eventually able to run Ubuntu on this machine? Thank you i (Hardware)
