Hi all, my PC recently developed a problem and I am unsure what it might be, and before I begin changing components I wanted to see if anyone else had any ideas.
Basically, I've had this PC for a while now, 3+ years, and it came overclocked with its profile saved in the BIOS. Everything was fine for just over a year, when I turned my PC on one day and it was stuck on the initial screen when you have to press F1 to enter the BIOS. There was no notable error message, other than it telling me specifically to Press F1 to enter setup. I noticed that the target CPU clock had reverted back to the original and the target RAM speed was all the down to 1333. I found the the overclock profile, loaded it up again and that was that, everything was back to normal.
I then noticed about a year ago, that if I disconnected power to the PC for long enough at the socket (not exactly sure how long, but maybe like 20-30 minutes) then if I turned it on again I'd get the same thing happening i.e. like the overclock profile failed and it reverted to some other safe clock speeds, but again I could just reload it and it'd run fine. This didn't happen if I didn't unplug it at the socket and left power to it even after it had shut down, so that power was still going to the motherboard and peripherals.
Then a few days ago I reset my computer to install some software. As usual, I pressed shut down, but this time the power on button on the case did nothing, like either the button was broken or something. I checked the power on button, removed individually the graphics card, RAM, hard drives, disconnected and reconnected wires and it still didn't power on. I then left the PC alone with the power disconnected at the socket. After about 30 minutes, I pressed the power button and it turned on. And I was again presented with the press F1 to enter setup and the reduced clock speeds. I reloaded the old profile, but when I pressed to save and reset the computer did not turn back on after resetting. Again the power button did nothing. I switched off the power again at the socket, waited, and again the power button turned it on and back to the same screen. This time I kept everything the same, but increased the RAM clock speed to 1800 MHz. After saving and resetting the computer shut off and after a short pause (like maybe 5-10 seconds, I thought it wouldn't work again) it turned back on as usual and booted fine. No issues.
When I finished I didn't shut down the computer but put it in sleep mode. The next day I resumed things as normal, until today when I was just browsing the internet and the computer suddenly shut off. Again the power button didn't work, but also this time leaving the power disconnected didn't seem to solve it either. And now it won't turn on. I should mention, when the power is connected, the peripherals e.g. my keyboard, is still lit up and the lights on the motherboard are lit up as well.
So now I'm unsure what to do now, or what the problem might be? Could it just be a faulty PSU? Or maybe a bad motherboard/BIOS? Or something else entirely.
(I should also mention that when I first got the PC turning on the PC power everything up momentarily (fans etc.), but before anything was shown on the screen the PC would just shut off, and then after a few seconds turn back on as if it just did a quick restart, and everything would boot as usual, but I never thought much of it.)
Any ideas?
