My computer peak remains depressing for some time after booting, what is the lead to?

It returns to commonplace brightness in a few minutes, and in that are no other problems.


Answer:

Does it happens everytime u restart? I tight if u switch on ur Sys 3 times in a afternoon, does the same happen all the 3 times?

If it happen only for the first time, don't bother as it can be because of cool climate or due to Rain. Though Computers r designed to cope near Cool climates best, but some times doesn't holds good.

Monitors hold something called Electron Gun which triggers the Production of Electrons. For this Electron Gun must roast up first. Whenever monitor gets on it is this Gun that heat up first but sometime may get tardy due to some Silly Tech Probs.
Ur system monitor is in problem. i reflect on ur system monitor picture tube is weak. Check it out next to the local service man.
your os could be booting up and hasn't sent the picture yet because at hand is no picture to send currently, your monitor could be self aligning/adjusting, if it go to normal after a bit I wouldn't contemplate it would be anything to worry just about. I think it is your monitor though. adjectives monitors act differently, some do test before displaying anything, some calibrate stuff, you never know. If it works, don't fix it. :)
Unless it is really annoying you, it may be best a moment ago to live with it. Its singular a couple of minutes after all.
if it fade to normal later the monitor is going bad (i bet your enjoy a CRT (big heavy monitor)). i'd suggest abiding up and getting a nice 17" flat panel.
