Hello, I have bought an empty case and assembled parts of Clevo P775DM1. Basically the laptop had no display or MXM Gpu or CPU. For test case I had a CPU lying around G3900 and put it in. I also have mxm gtx 965m Clevo card. I also have installed screen from alienware laptop 2k resolution 120hz. Now the problems. 1) The laptop boots without a hastle. But as the nvidia drivers load the screen goes black and stays like that. At first I thought the GPU was dead but the external screen worked. Then I though maybe there is a problem with GPU not being recognized or something. Downloaded GPU-Z and every sensor is working fine. I tried saving vbios file and suddenly screen turned on. It probably disconnected the GPU and reconnected it again and as long as the laptop is on, GPU works without a problem. But if I restart it, the laptop screen turns black after boot and external works fine. That's the first problem. 2) The second one is with Ram and I don't exactly understand the problem. I have 2x8GB rams 2133. single channel works without a problem, but when I try to use both of them the laptop does not boot at all. Won't start fans just blue led keyboard lights up. in single channel both rams work with no problem. And I've tried both slots, since the laptop has 4 slots. Still not working. If you can help with any of the problems, it will be much appreciated. p.s. I have recently bought the laptop and haven't really figured out anything around it. if you have any extra pointers/bios mods I'd really appreciate it as well.
