One circumstance I had with similar syptoms: my K-r was in Catch -in (trap) focus mode without my realising it. If thats on, then the shutter won't fire if the camera doesn't think is in focus. Check your settings, check if st happens when you hold the shutter button down and focus manually. If you were using an AF lens in any case then this doesn't really apply.
In any case go right thorough the set up menu and checK everything looks Ok.
Reboot? The only way I know of to do a "reboot" is a firmware update, definiitely try that. Eventually if nothing works then the conclusion is another electrical device with a glitch somewhere, who knows where, main ICB, sub component...
I second not economical to repair in that case: even if a replacement ICB/part was available. DIY job for s/o really keen basically, get another k100 off ebay spares/repairs...
