Question No display but fans are spinning

[Jatin9211]

I bought rx580 some days ago,plugged it in my pc but there was no display,swapped back to my old gpu and display was there.I checked every connection needed and 8 pin pci e was connected to gpu.
All fans are spinning but no display from 580.
Checked my GPU on friends PC it works fine.
Things I did were
-CMOS reset
My system specs are;
i5 2310
mobo-Dell gdg8y(from inspiron 620s)
8 gigs ddr3 ram
old gpu-gt 730
PSU-corsair VS550(new 3 days old)
I took it to a technician and he said my cpu gen is too old for gpu(i know it is old gonna upgrade in 3 months)
But from my knowledge i think it should atleast display.
i dont know what's wrong so your help will be appreciated.

I've set up system using 2nd gen ix-2xxx procs with rx580 no problem. Can confirm it does more than just display, works great, games great.

Bios flash to latest ver is the usual recommendation.
