Bad PPC?

I think, but I am not sure that my PPC is no longer working.

Here are the symptoms:
* When it boots up it locks when it should put the picture in the background. I'm using warp datatypes.
* If I boot with no start up sequence and run whichamiga it will just stop before it displays your system.
* If I boot with no startup sequence and run any warpos program like LHA or stat, etc it will lock that shell. If I run normal lha it runs.

I may be missing something.

Do anyone know of a way I could test it to be sure?

The fan is still spinning and I run the system cool.

Got to say that Cyberstrorms are crap, if this is a PPC failure. It will be the 3rd failure of the card in the last year and a half and it may be going back to get fixed again... sigh...

Thanks for the help.
