Windows 10: Horizontal white bars whenever I start up.

On Monday, I moved my desktop to my mates' house so we could game together. It was fine.

On Tuesday, I moved my desktop back home. I plugged it bak into my screen and turned it on. The first few start-up attempts, my screen just said 'No Signal,' which made me think that I'd forgotten to connect something in particular. However, it began the start-up process on the fourth or fifth attempt. But instead of the regular start-up, I had this.





And then that would repeat twice or thrice more. Eventually it took me to the start-up repair screen. I've used a system restore and I've reset my PC with files kept.

Since then all I've gotten is 'No Signal.'

Any ideas what I've done?

How do I remove the headings from the right hand tile area in Windows 10 start menu?

Thanks for responding. you said:

"Just click on the Title bar and drag it on the vertical empty side of the Start menu."

To the left? To the right? Up? Down? If I drag it anywhere to the left it does not flip to a vertical bar. If I drag it up or to the right it just drags right off the start menu, still horizontal and disappears, until I let go, when it just snaps back to
the original horizontal position it was in. I'm finding no way to do this. I expanded the start menu to the right and tried it and it still just drags off the screen and returns as a horizontal bar.

 

Flickering in Gaming

Whenever I play a game like CS:GO and roblox a white line flickers horizontally but I play alien shooter and nothing happens It works

But the screen flickers in CS:GO and roblox ? I want a fix please

 

Check that the graphics card is firmly seated.

 

If I try to move it slightly upwards and downwards, should it wobble at all?
