Hope someone here can shed some light on this. My PC normally boots up perfectly fine if it has been left connected to the mains. However, if I disconnect it from the mains, and then reconnect, it takes ages until pressing the power on button does anything. I normally have to wait until the power light shows on the USB joypad I have, to know when there's power running through. I've just changed the PSU but am waiting for the green light to come on so either the change in PSU didnt make a diference or the PSU is faulty (It's second hand).
Also when I turn the computer off, it wont let me turn it back on immediately. Even though it's just beeen turned on I then need to wait about 3 or 4 minutes until it will power on again.
Any thoughts as to what this could be please?
