Hi all, I turned my Pc off one night only to wake up the next morning and find the power on switch does nothing,

In order to start the PC up I have to press the power switch on the case and then flick the PSU switch off and on until it boots up.

Sometimes when doing this the led strip i have in the case will light up for a half second and then off again.

Eventually after turning the PSU switch to off and on a few times (sometimes it boots on the first off/on sometimes it takes multiple) the PC will fire up and run perfectly as normal with no power cuts or anything.

I gotta say its confused me greatly :p

At first i thought faulty cable but i changed this and no change.

Specs

Intel i7 3770k (was @ 3.8ghz but when problems started i put it back to stock)
8gb CL7 GSkill 1600mhz RAM
XFX 7970 3gb Black Edition
Sabretooth Z77 motherboard
Silverstone Raven RV01 Case
2x 3tb hard drives
1x 120gb Corsair Force 3 ssd
1050w XFX fully modular PSU
