Hello.
I have an iMac 21.5 with Snow Leopard and when it booted after 5 minute show me Kernel Panic page and I must restart it. How can I fix it?
Thank you.
Can the computer be booted without you getting a kernel panic?
Time to take it to a store and have it repaired. If you made any changes to the hardware recently (like adding RAM chips) then it would be time to undo the changes. Kernel panic is most likely a hardware problem.
Repair can be anywhere between free and very expensive / not worth it. Best case is some chips getting lose and putting them back in their proper places fixes it. Worst case is a broken motherboard.
Have you made any changes to your iMac, such as changing your memory, or adding any kind of external hardware?
If you haven't made any hardware changes or additions to your iMac - maybe the kernel panic indicates something else, like overheating, for example?
Check that the cooling air inlets are all clear, particularly the little round grill in the back, under the hinge, and above the power cord connector. (Users sometimes miss that one)

You have posted here before about your iMac suddenly shutting off.

Did you ever fix that problem? Or does it continue, and now is getting worse?
You may have a failing hard drive, although that can cause shutdowns during boot, when you first start your Mac.

Now I am curious...!It had a hardware problem. VGA was corrupted
Your post 8 said that you didn't change any hardware.
How did you fix the hardware problem in May?
I my previous iMac repaired via change VGA chip but I have a New iMac that is corrupted
We have 5 iMac and we want change them to HP Z800
Well, if it has Snow Leopard on it, it's hardly new... sounds like it is a 2nd-hand iMac...

If your "new" iMac has Snow Leopard, then you could try reinstalling OS X from the original disks.
I suspect that you will not be able to do that, as a 5 year old (or older) iMac may just have a failing hard drive.
It's not very difficult to replace a hard drive in one of those older iMacs.
