Constantly not getting a display to windows on boot up.

[lettuce]

After doing a fresh install of windows 10 i have noticed a number of times where i will turn the PC on and notice that im not getting a display on the screen at all, if i reset the PC then it seems to fix the issue and displays fine.

I have noticed when im having these issues after the mobo/windows 10 boot screen i will get a band across the screen approx inch width with garbled graphics, any ideas what the issue could be? hopefully its not my graphics card crapping out as only had it about 6 months

Im indeed using a DP cable, all cables seem to be secure. I have noticed that when i get this issue i dont always get the garbled graphics but my ASUS monitor does report 'no signal detected' which seem odd as it was detecting a signal as i do the display for my mobo logo, i have never had this issue before i did a fresh format and install of windows 10 and i never loss the display once windows has actually loaded only ever on booting into windows dose this issue happen
