With horrible pc parts price I bought this Office PC with a Asus Prime B360M-K to upgrade as a gaming pc but the chiniese GTX 1650 Low profile I bought does not boot sometimes. It gives 1 long beep and 3 short beeps gap and another beep. card fan does spin all the time.
Likely an issue with the card, if you can find another dGPU or use your CPU’s on-board video you can isolate as to whether it is an issue with that card specifically.
Likely the card has bad memory or a corrupted BIOS.
If it works sometimes and others not at all, it’s probably a connection issue. Bad memory or bios would either fail every time or cause corrupted output I think?
Edit: typo
