CPU: i5 3570k
Ram: 16gb ddr4 (2x8gb)
GPU: Dell OEM reference RX 570 4gb
Motherboard: Gigabyte ga-z77x-d3h (UEFI and Legacy dual bios currently)
PSU: Seasonic g650w
OS: Windows 10 pro 64bit
I was using the following set up with my old card GTX 960 2gb for the last 2 years. My friend no longer needed his RX 570 (he used for 1 year on his Dell inspiron prebuilt https://www.bestbuy.com/site/dell-inspiron-desktop-amd-ryzen-5-1400-8gb-memory-amd-radeon-rx-570-1tb-hard-drive-recon-bl… ) so he gave it to me. *It was working fine without any problems for his set up.
I put it in PCI-e 16x slot and 6 pin connector using HDMI to DVI-D cable on my 1920x1080p 60hz Dell LED monitor.
First try it would Post and fans spinning but with 1 long beep and 2 short beeps (beep code says its something due to GPU), so I searched on google and so tried the following solutions:
1. Took out all the cables from pc, psu and wall.
2. Restarted cmos battery (took it out for 8-10min)
3. Switching Ram sticks.
Upon doing the following solutions, beeps were gone!! But still remains no signal.
so I connected my old VGA cables to motherboard and integrated intel HD 4000 worked fine. I checked the bios and it was on UEFI and Legacy mode<--dual bios?), but didn't touch anything in bios cause lack of knowledge.
and then I've tried using DDU to uninstall all previous Nvidia drivers.
still no signal. GPU-z shows Intel HD 4000 when RX 570 is slotted in, but I haven't tried manually disabling HD 4000 (I think it disables automatically when new gpu is installed? correct me if I'm wrong..)
yeah, so confusion confusion... I need suggestions and solutions guys and girls. Any help will be appreciated!
