My computer restarts itself randomly. I have checked the memory, fans, general stability. It will sometimes restart and then have no visual display, as if the monitor was not receiving any signal.It has also booted sometimes with display corruption, with blocks of colours and 1s and 0s etc etc.Any clues? Im personally thinking power supply?Please help!!!
If it has a separate graphics card (i.e. not integral with m/b) try removing the card, cleaning its contacts, reinstalling it and making sure you have the latest drivers for it.
