Hello. I bought these 2nd hand RX580 4gb (2048SP) variant. At first, it works just like it should be. However, when i restart my computer, there was no video output shown. :( I bought the videocard dirty therefore, i opened it to check whether the thermal paste is fine or not. I also clean off the dust build up of my gpu and repasted the thermal paste. But sadly, there was still no video output. Is my card dead? Upon turning on my system with this rx580, the cpu cooler spins and it seems it is working. I also tried testing it with other computer with speaker on the motherboard and i heard 3 or 4 beeps? I am not sure. But the last beep had a delay. I tried using other gpu and it works well. All parts are brand new except for this gpu. Please help me.

I had no issues with the wifi card before. The speed is great and signal strength is fine. But after i broke the antenna (the locking mechanism detached) the speed went down. I replaced the antenna with my spare router antenna (signal strength recovered) but the link speed went bad. It runs around 10 to 20 mbps in speed in control panel but in speedtest.net, less than 2mbps. (On my phone, our home wifi runs 40 mbps. ) The computer is connected to 5ghz network. It is very close to the access point (2 meters). I cant use lan cable because it is the whole apartment's wifi. It has no restrictions and no speed management or Qos. Router is in default.
