I had been getting odd hardware lockups for a while, a good friend suggested that i try upping/lowering the ram voltage because he was having similar problems and that fixed it. well as i hit delete to try and get to my BIOS, the computer goes to a black screen and stays there. i can still ctrl+alt+dlt to restart it but i cant see any of my bios settings. Any ideas to help me fix this would be appreciated. I have a MSI KT333 ultra mobo. Thanks.
