Hey, since more or less one month I have serrious problems with kernel panic. I happens to me around 15 times a day sometimes it can happen even couple of times in the row. It is so annoying. Could anyone help me to detect what might be a cause of them? I am very affraid it might be something with the hardware. I say that because I installed a clean system and it happened as well. Also I have windows instaled on bootcamp and when I opend it it also crashed... Please help. Here is the crash report:

I have problems with him too:

WindowServer crashing is typically a hardware problem. Especially since Windows is doing it too.

Thanks for answer, but is it possible to find out what part of hardware is causing problems more specific? Or I just have to give it for a check. It's not on a guarantee anymore so I am afraid it will be rather costly...

It's difficult to say. Something is causing WindowServer to say "Nope, can't do it". While that's probably the GPU, it's never so clear with this kind of thing. Plus, if it's another component, it's possible that the crash log isn't the same every time. There's a lot you just can't know. You'd have to take it in for a check to be certain.

EDIT: Oh silly me. I almost forgot... There's a hardware check you can run by booting with the D key pressed. Once in, run an extended test and see if it tells you anything. If it tells you nothing, then the above still applies.

EDIT2: If your computer is over a certain age, you may need to find the installation disk for your computer in order to access the hardware test.

This article suggests that turning off graphics switching can stop the kernel panics. Have you tried this? If it works at least it can get you by until you can afford a hardware repair if necessary.

@ConCat: Thanks for the tips, but I can't enter the hardware check by pressing D, I have read (and as you said) that I might need an instalation disk. But my mac is mid 2010 and it came with no instalation disk. Any tips what I should do?

@swerve147: The thing is that I want to use my external display, and in this case you can't use intel graphics. I will try to work some time without external display and see if it makes any difference. Anyway I will test also with only Nvidia card, maybe the switching is the problem.

Anyway, thanks for help guys!
