When i start my PC it beeps and then restarts, i can't even get to BIOS because nothing shows up on my monitor. Also i know this can happen if you mess with the BIOS, but i have not messed with the BIOS at all. If i open my PC and unplug everything and re-plug it all (all cords and memory / video card)
it MIGHT work, but then the next day it's back to being broken with the beeping and then restarting.
 
Solution
Start with trying another video card or the mb video chipset on next failure.
If still won't post right try one dimm at a time to rule out ram. If not ram issue it could be a failing power supply.
