Aah. Maybe that's the case. I have been completely sure that it was only because I'm not a Linux guru, but I have seriously searched the whole internet. My computer is completely new, so I guess I will send a mail to the shop and ask for a new card. Thank you for your answer.

Re: My system is very slow

I don't know if this has anything to do with the computer crashing, but I don't think it seems very pretty. I got this message today:

kernel:[10998.340022] Disabling IRQ #16

and I have no idea what it is. After a bit of Googling I have concluded that something isn't right. Can this be something that makes the computer slow/crash?

The last lines of kernel.log says:

You have 2 Ethernet ports. One of them is sharing IRQ with your Graphics card. We can later figure out how to avoid it. For time use the second Ethernet port and reboot. Your Graphics problem will also vanish.

Thank you so much! I have rebooted now. There has been two days without a crash now (that has sometimes been normal), so I guess I can't say if the problem is solved today, but I guess this thing solves the stuff :)

Glad to hear that your PC is working fine..Wait for couple of more days and if things look good, please comeback and put [solved] in the subject line of the thread to mark it closed.
