I'm having a problem with my PC. It will randomly turn off/crash as if the power has been cut.
This usually happens when triggered by something visual. For example, gaming is the most common culprit, it will crash during some games at random or trigger crash by some start-up or load screens meaning some games I can't even play because they always crash my PC. The power on/off button on the front of my case doesn't work anymore like a normal PC, to even get it to turn on I have to have power going to it, but have to jiggle the connected power cable in the power board I have until it hits a sweet spot and powers on, this can be interrupted if the jack is moved even a milimetre, causing it to turn off again. I have to do this until I see my power button light up fully and stay on. This is why I think it's a PSU issue. I'm wondering if my power unit isn't sufficient enough or is faulty and my PC is crashing because of a power usage trigger. I wouldn't even be able to use my PC if I didn't have this particular power board because I've tried to wriggle the power jack cable into other sockets or power boards and haven't had the same luck. So it's a miracle I can even get it to start up. Is this a power unit issue or something else? Is there a way I can tell / find out what's happening exactly internally that is causing the crashes? How can I fix this?
Other info: The PC is obviously pretty new, I built it last year. This problem started happening about 6 months after assembly, before that it was working perfectly. I have cleaned out the PC recently, checked all cables were connected, everything seemed fine and in working order. There are no visible indicators that anything is wrong.
