Ok this is a weird problem im having here. I turn on my computer and my mouse/keyboard wont turn on, ok so after figuring this out i thought my motherboard is done BUT! After around 5-10 restart of my computer the mouse/keyboard works and loads windows. I tryed so many things on trying to fix this like reinstalling windows and switching USB places my keyboard is a PS/2 and my mouse a USB. I tryed using an adapter for the mouse instead of USB didnt work. When i start my PC is loads my motherboard window usually asking to press Delete or TAB to enter BIOS or Post.. Im so confused about this problem does anyone here have any more ideas on how to fix this? Thanks

What kind of a motherboard do you have? It almost sounds like your keyboard/keyboard port is going to heaven.
Have you tried with a USB/different keyboard?
Look in your BIOS and enable "Legacy USB Support" that should solve your problem.
