@VANT: with all the bad luck i'm having at the time you could be right
@Evolva: it was funny, i wanted to burn a cd-r that didn't work, because Nero closed every time i added some files. Then i tried to burn a dvd-video which stoped at 1% of the burning prozess.
I thought that Nero went bad and reinstalled it, tried to burn the cd-r again worked, but the comparing of the data stoped at about 57%, i thought so what and burned the dvd-video, everything was good until nero opened the tray.
When i reinserted the dvd the burner tried to read it but couldn't and i wasn't able to get the dvd out again so i rebooted. Now the Pc waited at the boot screen and told me that i had no drives installed on the second IDE channel, also windows stoped loading at the boot screen.
So i removed the drive from my pc and now everything is running again but the 4163b.
May it rest in peace.
And about the cup holder, now that is one thing my stepfather would do
