I just joined this forum after finding on google that someone here is having my same problem. Im not sure what are the rules on crosss posting, but i feel like this topic is better suited for this board anyways. Link to page for of the topic Cliff Notes - New Built Computer, Intel Pendium D w/ 430W PSU - Power Cycles but doesnt boot up when plugging in a BFG 7600GT. - Computer works fine when card isnt in the computer. - Cleared CMOS, problem still happens. - BFG says its their cards problem, but im not 100% convinced of that. Im still doing the RMA they allowed me. One thing i havnt tried is another power supply, which i will try if the new card they send me still has problems.
