Pegatron 2AC2 Motherboard
Processor i5-2400s 2.5ghz
450psu
Trying to upgrade this from onboard graphics to a PNY Geforce 1030gt pci-e GPU.
After installation, No display. GPU fan is on. LEDs on. Gives 1 long beep followed by 3 short beep "error".
Only software i have tried to update was the BIOS. There was no update for my MB for Windows 10 so I looked up Windows 7v and installed because other people on different threads have had success with this process. Same Result.
The stock PSU was 250w and i also upgraded to 450w so that is not it. Any help would be appreciated....

Hi:
Unless the BIOS version is 8.1x or newer, your PC's motherboard is too old to support anything newer than a Nvidia GT 6xx graphics card.
I think the BIOS version for that motherboard only goes up to v7.16.
