Hi guys i was wondering if anyone could help me with my problem, i have recently bought a new psu(Pro XFX pro 750w) and graphics card(gtx560 TI hawk edition), i have installed both of them correctly i assume, i then hooked it up to the power and when i try to turn on te computer it would turn on for about 2 secs and then off for 2 secs an so on, it repeats itself. Would like to know whether i did something wrong, or is there a procedure to undertake or what so. If anyone could help id be sincerely grateful
