About a month ago I noticed that I can no longer put my PC into sleep mode. If I try, the PC begins to power down towards sleep state, but then switches off suddenly, much quicker than it should. Upon rebooting the PC, I am confronted with the Windows Start-up Recovery Screen (Start Windows normally, etc.)
Now a few weeks later, when I power on the PC (first boot of the day) the LEDs on the fans flicker, and you can physically see and hear the PC struggling to start-up.
So now every time I turn the PC on, I must go through this procedure:
Turn off the power at the switch on the back of the power supply;
Wait a few seconds for the LED on the front of the case to go out (about 3secs) to make sure the juice is truly drained;
Switch the Power back on;
Press the case front power button, and then the system boots just fine. Runs all day with no problems, including gaming, etc.
(sleep mode still doesn’t work; I've resorted to turning off the PC completely now every day).
I'm thinking that the initial jolt of power when I switch it back on, juices-up the PSU (or whatever) just enough to get the system going, then it is generally running perfectly. (very occasionally, the power will cut-out before Windows has finished loading, say about 60secs after a "successful boot").
My question is, is this a PSU or motherboard issue, and how do I find out?
Is it worth buying a PSU tester/trying another PSU, given that it seems to cope with anything I throw at it after the PC has successfully booted?

- as usual) to test the psu using a paperclip to bridge the connections, I noticed that the fan on the bottom isn't spinning any more, and now nothing happens apart from an unhealthy hissing noise.
