A week ago I installed Ubuntu 10.04 in text mode and every thing went just fine during setup but I had problems before installing.

In installation I couldn't start it in graphic mode, my DVD reader seemed to be reading but nothing happened. I installed Ubuntu to my old laptop (which is capable of working Ubuntu), it booted after the first run I got a whole white screen that I couldn't fix for 2 years.

Now Ubuntu 10.04 is installed on my desktop but when I choose it from grub, nothing happens only the power of monitor keeps blinking. That's all. Nothing more.

I wanna use Ubuntu but I can't find the problem.
