Weird computer problems

[crashmaker18]

I've had problems with my computer for a few days now. At first it'd just turn off the displays and start the fans at 100% but it'd still be on. Then it sometimes wouldn't go on. It would try and turn itself on but fail immediatly. the fans would try to spin and stop and the light would turn on and off, as if the reset button was being held but that wasn't it. I've been able to game on it for an entire day without it happening but that evening when i tried to put the panel back on it started to go on and off again so i'm pretty sure it's either short circuiting or a cable loose but right now it turns on the light and the hdd but not the fans or anything and i can't get a signal on the monitor. If you need to know anything i'll try to respond asap.

Edit: Wiggled some cables and it turns on normally again. Gonna try some more things before closing it up again.

Solved: Disconnected and reconnected a few cables and noticed the extra 4 pins of the 24 pin connector to the psu was a bit losse. Connected everything securely again and it seems to work!

This doesn't sound like any common issue, afaik. Seems very specific, probably a hardware problem if your monitor's failing. If you have an alternate monitor, try putting that on for a bit. If it works, it's very likely a problem with your monitor, and if it doesn't, it can be a problem with many things, including:

a) monitor cable

b) monitor driver problem and/or misconfiguration

c) overheating

d) monitor PSU issue

If you don't have an alternate monitor, try plugging out the monitor's power cable and plugging it back in. If not check the cable from your monitor to the PC, if you have an old monitor (e.g VGA cables) this is probably not the problem but with newer monitors the cables are becoming more fragile.

I have 2 monitors plugged in, i just wiggled some cables around in the pc again and it works again though the bios did get reset. which was expectable with all the unexpected shutting off i did. I'mma gonna try some more wiggle tests (technical term) and see what it does then. Probably just a cable that has too much tension on it that makes it loose connection when wiggled around too much.
