My pc had a really crappy psu which got burned out after overheating. Smoky smell and everything. Now I replaced it but it won't start up normally anymore. I don't understand what else it might have damaged after it overheated. Im wondering it might be the cpu but I want to know if this is common. The issue is it freezes on start up wont let me get into my desktop on Windows 10. I can log in some times and I can go into safe mode but not use it as I regularly would. I don't have spare parts to test if it is the cpu or not.
