Computer starts like an old car engine
Ever since a power failure a few months ago, when ever there's a power failure (the only time my computer is off, in other words, whenever the computer is turned off for more than a few minutes), when I try to start it it's like starting an old car, let me explain:
If I press the power button the fans will spin for a second and stop, I have to hold the power button in and it'll actually start like an old car engine, as I hold the button the computer fans will go "rrr.....rrr.....rrr.....rrrr.....rrrr" and often I'll have to let go of the power button and press again and eventually it'll start "rrrr....rrrr....rrrr....rrrrrrrrrrrrrrrrrrrrrrrrr rrr".
What could be causing this? I assume it's either the PSU or motherboard.
Has anyone seen this type of problem before?
Other than that the computer runs flawlessly once it's started, but there certainly is a problem somewhere that I'd like to fix before it possibly gets worst.
You may recall I posted about my computer making a strange high pitched sound for a few weeks a few months ago, but that sound has stopped, but I assume it could be related to this new strange problem.
