Over the past few months my PC has been acting strange. When it is running, everything is completely fine. But it can be very difficult to turn off if certain circumstances are met.
I built my PC in September of 2011, and the only thing (besides peripherals) that I have upgraded since then is the GPU. I'm running an i5-2500k on a Gigabyte P67A-UD4-B3 motherboard with a 1000W Kingston PSU.
To get right to the point, if I shut down my PC through Windows I have no problem starting it back up. However, if I completely remove power from it, such as switching off the PSU or power bar to it, it will not turn on and takes a lot of coaxing and time to do so.
Also I've noticed, that if put it into sleep through Windows, it will essentially crash itself and shut down, completely removing power to itself and being difficult to turn on again.
It also goes in this state if I physically shut it down with the power button on the case.
Now to explain this complete 'loss of power' state: when it goes into this state, if I hit the power button nothing happens. it doesn't turn on. However, power is getting through because the keyboard and mouse light up (and do some very unusual light patterns) - this tells me power is getting through the motherboard somehow.
To turn it on, I have to coax it as I mentioned earlier. This involves pressing and/or holding the power button multiple times, and play with the PSU's power switch. If I switch off the PSU, wait a few seconds for all power to drain (keyboard lights go out), and turn it back on and then attempt the start the computer, the computer will proceed to start for a second and then die. I usually attempt this multiple times until the computer finally starts. It's like a bloody 2 stroke engine that you attempt to prime.
My original thoughts were that the motherboard is dying, since it's pretty much ancient at this point. However I left for the weekend and before I did, I turned my power bar off, so when I came home I spent half an hour trying to get this bloody PC to start. And that's when I thought that it really could possibly be the power supply.
But I really don't know. I'm positive that it's one of the 3 components, and I am really hoping it's the PSU since it is a much much cheaper fix.
Any thoughts are appreciated!
