Question Three year old system acting weird.

[nikhilsaxena835]

Specs :
Asus Ex A320M Gaming
Ryzen 5 3500
Circle CG Raw Power 550W 80Plus White

Problem : I push the power button and the system doesn't boot up. I can see that motherboard's RGB are lit up. After sometime (approx 30 min) the system magically boots up.

What have I tried:
1. I did the paperclip trick and the PSU starts.
2. I tried to jumpstart using the POWER_SW pins but it didn't worked.
3. I checked all the connections are tightly seated. But if they weren't the system wouldn't start after sometime.

I think it's the power supply. The problem is that both motherboard and PSU will be out of warranty within 20 days. And where I live, any replacement will take 15 days for exchange. So, what do you guys think. Should I send the PSU only or should I send both motherboard and PSU. Also, I do not have any alternate powersupply lying around for diagnosis and the nearest computer expert is 150 miles away.

Edit: I forgot to mention, when things were normal a week ago. The system will start but it used to take some 10-15 seconds for the keyboard and mouse to get power. This has been since I first built the system.

Your PSU sounds dangerously cheap after I converted the price from Indian Rupees. The name alone "Raw Power" does not inspire confidence. It's just "marketing speak" designed to snare the unwary.

If changing the CR2032 BIOS battery doesn't fix the problem, return the PSU, keep the motherboard and buy a better PSU costing at least twice as much.

If you get a replacement for the Circle G Raw Power, sell it to help pay for a decent PSU.

Alright. I was getting the feeling that the brand is not good. But now I am definitely not installing a Circle again. It was a bad choice honestly, I tried saving money wherever I could. Thanks.

So something undesirable happened. I went to the PC shop where I purchased my components. And the PC started just fine. I made videos of it not starting including jump starting, psu paperclip trick etc. So the technician there took the pc for sometime and after a week it is still working fine on his shop. But when I brought it back it started giving same problem again. I tried another PSU and the problem persists so, I sent my motherboard for warranty and the problem is still here. At this point I am clueless what is the problem.

Try plugging it into another 110VAC receptacle, maybe in another room.
Could it be an electrical problem within your living quarters?

I had the same problem and it was because of my motherboard.

I need to ask a few questions about the conditions in which your computer is working, if I may.

Do you at any time experience temperatures above 35C. Operating a low quality PSU at high ambient temperatures over 40C could cause it to fail.

Do you experience high humidity (Monsoons)? Damp humid atmospheres can cause component pins to tarnish or corrode.

Is your local mains supply nominally 220V AC or 110V AC. Is it town/city mains, Hydel (hydro-electric) or petrol/diesel generator?

How stable is the mains voltage. Do the lights in your room get brighter and darker over time? Do you suffer from power cuts or load shedding?

In my travels I have measured mains supply voltages as low as 55V AC and as high as 330V AC.

Most ATX PSUs are labelled for operation over the continuous range 100V to 240V. Anything way outside these limits is bad news for your computer. I'd be worried if the mains voltage dropped below 90V or went higher than 260V AC. At voltage extremes, electrical equipment explodes. I've seen it happen.

There is obviously some difference between the the shop where your computer worked and your home where it doesn't work properly. Mains supply voltage and quality could be one variable.

I have tried it. In a different room, in a different house and also in a different city. Problem doesn't goes away.

Yes the temperature here goes above 42 during summers. So, the system temperature too goes beyond 50C. My town has 85% humidity today and it will stay at these levels until August ends. The standard voltage is 230V. Power cuts and load shedding is not frequent but yes, it does happen atleast twice a month.

I had the same problem and it was because of my motherboard.

I was really hoping that it wouldn't be the motherboard. Those ASUS people are not giving me my warranty. In worst case I'll have to buy a new motherboard.

So, new update to the whole nuisance. The system will boot up normally when certain conditions are matched. The conditions are:
1) The PC must be connected to the AC Mains but with the switch off.
2) The PSU switch must be on.
When I leave the CPU this way, it turns on like nothing happened. Any other combination of these switches result in the problem to arise. What do you guys say?
