Problem: Desktop randomly turned off while playing Witcher 3. I tried to switch it back on, but nothing happened. The keyboard is still on, and when I unplug and re-plug in my PC, the light will come on for maybe half a second, as well as the fans, but then nothing whenever I try again (although keyboard is still receiving power). My speakers are also repeatedly making very quiet buzzing sounds off and on. Please help.
More Background: I built my gaming PC 4 years ago, and have had no problems since. However, after switching it on for the first time in 3 months, it turned off mid-usage. I then turned it on and it continued to work fine. Over a week later and this has happened again, except I cannot switch it back on again.
I have since cleaned the large amount of dust from within the PC, as well as vaguely check to make sure all the wires are plugged in properly, and that nothing is touching the motherboard that shouldn't, but it still doesn't work.
Possible Solution: I have a spare power supply which I could try, but it will take a while to set up so I would like to know if there is anything else I should try first/ if this doesn't look like a power supply issue.
Thank you so much to anyone who can offer any help, know that you will be making my lockdown experience exponentially better if you can help.
