Today I already wasted all afternoon trying to guess what's happening with my pc and my brand new GTX295. I bought it and many $$$ went out of my wallet, after that i was back home excited and bump... no start, just red light coz my brand new PSU is 800w BUT doen't have this damned 8-pin connector, only 6-pin. I went out again and i've found only Cooler Master Real Power m620 PSU equipped with two 6-pin connectors and finally one 8-pin. I mount it and ok, seems fine, green light now... BUT NO VIDEO! I'm lost, i'm thinking to kick my pc case, damn... Anyone can help me out? MY rig is old: Athlon FX 4600 X2 Motherboard M2V 4 Gb RAM 2 hdd 1 SB X-fi Soon will buy other parts for a brand new pc.
