So just now i unlocked my Sapphire Nitro RX 460 4GB with this guide https://overclocking.guide/amd-radeon-rx-460-unlocking-... , i already did this once sometimes and it suceeded. So this time i decided to do it again because of bad performance . After doing it, i can’t say if it failed or suceeded, because after doing it, my amd driver didn’t recognize my gpu, so i tried to reflash it with ATIFlash using my BIOS backup. After the flashing, i restarted my PC and... it won’t boot up! I turned it on and it beeped 4 times and nothing showed. Please help! Need to use this PC fast. Thanks.Specs : AMD FX 8320-ESapphire Nitro Radeon RX 460 4GBGigabyte GA970A-D3P16 GB RAM
