Screen Flashes on Startup - Information please

  johndrew 12:03 16 Jan 06

My PC starts and runs but I have just noticed that:

1. after the BIOS screen the screen goes blank then the Windows "loading" screen comes on

2. when loaded the screen goes blank

3. the screen backlights then go off

4. backlights then come on

5. backlights then go off

6. backlights then come on and the "Welcome" screen appears

Is this normal? If so is it caused by programs loading or what?

I have seen something very similar to this on a few occasions on different PCs that otherwise seem to work fine. I had concluded that it was somehow related to the loading of the startup items, but don't know whether I am correct. Anyway, I don't think you need be concerned.

Thanks for your response.

I am not concerned as the PC is fine in all other respects. It was curiosity that made me ask.

If you watch the screen after it gets to the Desktop you can sometimes see it flicker (as other programs load presumably) so your theory looks plausible.

It is a pity either no-one else has any idea of the cause or it is of no interest to them.
