WinAPI program: "Entry Point Not Found" after 2 hours

[Pranciskus]

WinAPI program drops box after approximately 2 hour of working: "Entry Point Not Found" and computer crashes, I have to restart. Is there any solutions for this? What can cause it? I didn't find anything helpful on the internet.

The entire system crashes? That really shouldn't happen. Are you interacting with a driver or something?

The problem probably was that I mixed dbg and rel libraries. Actually I added them both and probably visual studio picked dbg libs though I use release build. now 4,5 h nothing happens yet. I hope it will keep working.
