No post No display ati 5450 can't disable onboard graphics help!
Hello People of Tom's Hardware this is my first post but i've been building pc for a numerous amount of years and always came here whenever i had a problem however this time i have exhausted just about every thread relating ot my problem so i'm hoping somebody out there can help me i don't want to hurt my pride by resorting to taking it into a shop for repair.
Basically i have an asus p6x58d-e motherboard and an i7940 which i know are both working fine i have dropped these into a new build computer added 4gb of ram an ocz 600watt psu and attempted to install an ati 5450 today but no matter what i do i cannot get the system to boot or post there is no display coming i can't disable onboard graphics (which i suspect the problem may be) because the stupid motherboard doesn't come with any connections to support integrated GPUS so i'm stuck i cannot get into windows or bios i have no idea what i can do i've tried clearing cmos checking the ram i dropped the card into another rig and it works fine so the card is not the issue before the motherboard had a gtx 470 in it so i don't know whether this may be a problem connected some speakers and there are no beeping sounds the pc turns on and all fans spin correctly and lights up any help would be greatly appreciated
Regards Mat
