I just built a new computer. worked good for 2 days then yesterday when i powered it on it stayed on for 1 second, powered off and reset. it did that twice then worked fine. today it wont stay on it just powers on then off on then off...
any advice, i was thinking maybe it has a short some where but everything looks good.
Normally when a computer does this it is because the power supply is bad, also computers can do this if they detect the processor is overheating, check that the processors heatsink is fitted correctly and that the fan is running.
The fact that the power supply started up without the 4 pin connector fitted means that the power supply can’t supply the required load, either that or the motherboard or processor is faulty. The fact that It managed to start after turning on and off would indicate that the motherboard and processor are ok.
