boot - Black screen, blinking cursor and purple line left

Last week I installed Ubuntu on my notebook, now I'm also trying to install it on my PC, but with no luck.

When i start from my USB stick (same as I installed my notebook with, Ubuntu 13.04) first I'll see an purple screen, after this it shows a black screen, blinking cursor and the a small line on the left is purple.

I've started searching on Google, and tried the nomodeset function on the first black screen. Here it doesn't show the purple line on the left, but still an black screen with blinking cursor..

Now I tried to install 13.10 and 12.10 on the USB stick, but with no luck. Exactly the same things happened.

After this, I tried some other things:

acpi=off = Same effect as nomodeset.

nolapic = Same as "normal" boot (purple line, black screen), but without the blinking cursor.

Desktop specifications:

• Intel Xeon E3-1240 V2


• GeForce GTX 640 Ti BOOST


• 6GB of memory


• 3 displays, the purple line is always on the "main" screen (middle
  one).



• Currently windows 8 pro installed.


• ASRock B75 Pro3-M
