I overclocked my desktop from 3.6 to 4.2 in the BIOS, it's an ASUS motherboard and it's an AMD Radeon Graphics card. Now when I turn on my desktop, the screen is just blank. It's not the screen, when I unplug the screen it says 'Not connected to visual output'. I've tried putting the graphics card in the three other slots available on the ASUS board, and I've even replaced the graphics card with another graphics card from my roomates computer and tested that in two other slots. When I boot it up, I don't even see the BIOS.
Any identification of this problem? Is it common? Any quick solution? It is an ASUS motherboard so it shouldn't break like this, but it can't be the graphics card as I've tested it with another one.
