right I'm trying to install my ATI X800 SE and I've done all the right steps of cleaning my old gfx drivers and stuff out, but when I install the ATI into my pc and try and boot, I get beeping and in red writing something like I havn't install power to my video card bla bla... I didn't get a power suppile with the card? or dose it mean my std PC power can't handle the card???
