My pc fails to boot. I have a core i7 8700
,gtx 1070ti rig with 16 gigs of 3600mhz ram. My pc turns on then all the case lightnings turns on but it doesnt display any thing. It just displays the input source (display port) at the top right corner of my screen, the rest of the scree is whole black. It does boot successfully sometimes but even after the successfull boot the pc crashes frequently. I checked the display port cable, i ve also made a bios reset (with the onboard bios reset button on my msi meg z390 ace mobo ), but nothing works. Please help me.
