Computer has a delay on powering up after pressing power button

[wesleydn]

I press the start button on my computer and mostly it will take a 5-10 seconds before it actually starts up sometimes longer, other times it doesn't start. If i unplug the power and put it back in it starts up as i press the power button. Any ideas what the problem could be?

U can try the fast boot feature in boot menu.... sometimes it happens if the bios fails to load... Do u here any sound when the computer is not starting--like a beep or something?

Ill activate the fast boot feature now and test it.
No sounds or beeps from the computer, i press the button then silence until it starts up

Side note/question
After i updated my OS to 8.1 it seems to start up A LOT! slower than it did before anyone know why?

Test it...if it does not fix it then run memtest....See if its a ram problem... B4 that if ur rig is an old one try to clean the interiors and reset the ram (if not liv it)... U cud also clear CMOS by pressing the CMOS button on board...Try these only if the first method is of no use...

It's most likely a PSU problem. My old Dell takes 5-10 minutes to start up after pressing the power button, and that's because it has a bad PSU.
