Had my computer for around 2 years and never had a problem with any of the parts. However over the last few weeks i have started to notice a smal issue. When I press the power button normally the machine would more or less power on instantly. Over the last week or so however when I press the power button it is taking around 10 seconds for the machine to power on. Should I be concerned with this? The last thing I want Is for the PSU to blow and take several of my components with it. My power supply is an xfx black edition 750w.
