Hey guys, I changed my kr7a-raid chipset fan to a thermaltake blueorb, and when I power up, and have a black screen, nothing comes on. I get all fans working, I get the green lights, but no start up? Is my video card the prob? It's a radeon 7500 oem, I overclocked it with powerstrip to 258/260 I think, somewhere around there, been working fine, but maybe it died. I completely checked everything out, took everything out and placed them back, still the same. The green lights along with the yellow on top of the green means that everything is fine, and the mobo is not dead? I'll probably buy another v-card to test, then return it if that's the culperate.
