I have a brand new Radeon 7000 multi-display edition. When I plugged it into my 2.4ghz box and pressed the power button, the computer powered on, monitor powered on, but nothing came up. no beeps, no bios, nothing. (old video card still works in that box). Tried it in a 700mhz no joy either. Tried it in an old 233mhz, and it worked great. Any ideas? O_o I'm confused.
