Question about the boot up sequence of new pc

[Davy_b]

hi guys , i just built a new pc 2 weeks ago and i have a question about what it does during boot up .



when i press the power button it goes through the normal system info and motherboard info and then starts the windows loading where the 4 colours come together to form the window , but just as the colours come together the pc switches off for an instant and switches back on in the home screen (normal screen as if nothing happened ) and you can work away , just wondering is it normal for the pc to switch off for an instant during the loading of windows , or what is going on ????



sorry i know its poorly explained but i dont know how else to describe

Are you sure it's your PC switching off and not your monitor reacting to the change in image/resolution.

If your PC switched off then it would start the whole boot process again so I doubt it's that.

well the back lit keyboard switches off aswell for a second and the pc beeps like it does , when i press the power button to start it up ??

the Monitor is a Dell Ultrasharp U2412M

Are you sure the PC is actually switching off?
Like do all the fan's power down?
My monitor goes off when it boots up and back on.

i wouldnt imagine t being the computer relooping then coming on in windows

as above do all the fans stop spinning

My backlit keyboard turns off for a few seconds too, and there isn't a long enough delay for my monitor to turn off but I think it would if I didn't have an SSD in boot up. It is just a transition between the startup screen and login screen.
