Clarification Request
So is the issue the white dot stays or goes as the PC boots?

I'm encountering new to PC folk that demand that the startup be flawless. They won't accept the usual digital noise or screen jitter that you see in many of today's designs.

If the white dot goes away as the PC boots, then you should not fix it but learn that PCs for decades have done this and more during boot.

Stays on the PC

I don't really want my startup to happen fluently i can wait 10mins I just want to see if it will start the OS so i can start playing games. And it doesn't go away i will let it stay there for 20mins and see what happens

So this sounds like a display or graphics card issue.

The i5 appears to have a video section so retest without the GPU.
