Before starting let me introduce my systems (better one is mine and other is my brothers)
CPU: Ryzen 5 1600 @3.9 ghz (now it has stock settings :/ )
Motherboard: Asus Prime B350M-K
Ram: Hyper X 8 GB 2133 Mhz
Hdd: Toshiba 1TB 32Mb 7200 Rpm
GPU: Asus Strix Gtx 1070 Gaming OC
PSU: Dark Force 500 Watt
My brothers system :
CPU: Intel G4400
Motherboard: MSI H110M-PRO-VH
GPU:MSI 1050 OC
PSU: Powerboost (very bad) 500 watt
Rest of the systems are same.
And my problem is , i bought this 1070 couple days ago , my system was running quite stable before it , when i install 1070 in PCI express slot and press the power button there is no output from graphic card , i tried dvi , hdmi , even hdmi to vga connector. But when i remove 1070 and put 1050 in same slot , it is running perfect stable with 1050 and also when i install my 1070 to my brothers system , it is running perfect stable as well (GPU-Z render test about 1 hour) . I tried to change rams but they have no problem either with my system or my brothers system. I even unplugged my brothers PSU and use its 8 ping GPU connector with only my 1070 which is installed in my mobo and rest of the system powered with my PSU , then i still get the black screen but the fans didnt stop and run (i guess %100) very fast non-stop.(With my system the fans run about 10 seconds and stop). I dont know what caused this problem but everything in this list seems perfect stable except when my 1070 plugged in my mobo
I hope anyone around there can help me fix this. Sorry for bad english i hope u understand me . Thanks for any help
