Hi, this is my first post to this forum. I'm building my second computer and I have a problem with my MSI gpu. Everything works fine until I attach my MSI gpu. When the gpu is attached there is no signal to the screen. Works fine without the gpu, already installed Windows & drivers. The gpu becomes powered, fan goes on normally. Already tried both PCI-E slots and all different ports for screen connection. Youtube and Google did not help so I hope the community can! Motherboard: Asus F2A55-M LE GPU: MSI R7850-1GD5/OC CPU: AMD A8 5500 RAM: 1x Corsair XMS3 DDR3 4GB PSU: Corsair CX750 HD: Kingston SSDNow 120 GB No chassis Screen: LG Flatron W2452T (old but works fine without the gpu) Thank you and sorry for possibly bad english!
