(SOLVED) PC turns off without warning then turns on immdiately

[WEIBO]

Hi, this bothers me all the time. Appreciate any suggestion.

Let me discribe the whole situation. After it is assambled, sometimes there's blue screen when using. Finally I found it could be the motherboard RAM slot problem. I switched the two rams to the other two slots, not going blue screen anymore. Then maybe two months later, the desktop starts to turn off without any warning and then immdiatelly turns back on and ask me to log into WIN10 like nothing happened for like around twice per day. When it goes off, cannot see any flash of the lights or any other electrical appliance. I don't use any UPS currently.  I tried to check the connection between the power supply and the motherboard and I think it is tight. Yesterday it even turned off during my checking the BIOS, so probably it is nothing to do with the software. (I checked BIOS because on the webpage of the RAM it is said 1.35v but in BIOS it is only 1.2v. But it turned out to be the 1.35v is the tested votage and 1.2 is the PSD votage so it should be fine?)

I am thinking about three parts:

1. RAM itself

2. Power Supply

3. MD

But I dont know other ways except for buying new ones and replace these one by one to confirm the problem. Or it could be the connections between those?

Please tell me if there's more info I should provide. Especting for any help! Thanks!

Any overclocks on the CPU? 

[TurtleZero]

Unfortunately this can potentially be a very tricky issue. Once I had the same situation as you described, but it was a combination of the graphics card and the power supply.

[Rappalores]

It could always be a faulty PC part to say the least, I highly doubt it's a software issue.

 

I'd look into PSU and the mainboard. Check if every connector and pin is connected properly. I had these problems as well, both with loose connections and a faulty PSU. If you keep going much longer like this you could end up with a lot more damage on your PC (if it is the PSU).

No. not any OC

[bcredeur97]

you need to watch power supply voltages if possible up till the point it happens.

 

sounds like it could be a vdroop problem. voltage drops off, causing system to just halt in the middle of operation.

 

kinda like when the battery in your phone gets old and it dies at 10, 20%... it's due to it not being able to maintain appropriate voltage without random "dips", some of which are severe enough to cause the device to shut off.

 

(which is exactly what apple was trying to prevent with their throttling that everyone was complaining about which I don't get but w/e thats another topic)

Thank you! If it is software then it should not happen during BIOS right? I'll double check the wires from the powersupply and every pin. Last time I unpluged them all and set them back but it didn't solve the problem.

When I had an issue like this, it could happen after 20 minutes in game, 2 hours of idle, or immediately on start-up. It ended up being a faulty PSU. The faulty PSU in question was an EVGA SuperNOVA 850 P2.

Thank you! You mean it is the powersupply itself cannot maintain the voltage? Or it is the surge thing going into the power supply caused the problem. Is there a way to monitoring the voltage number all the time?

Thanks. Ok, maybe I need to by a higher watt powersupply of other brand first to see if it is the powersupply's problem.

You don't need a higher watt PSU. And you don't even need to buy anything other than EVGA. The G and P series are generally very good units, but electronics can sometimes be weird. Unfortunately, unless you have another PSU, there really isn't any way to test unless you have an alternate PSU. I was fairly certain it was the PSU when I turned off the ECO switch and the PSU fan would run at 100%, 100% of the time. Making me think that the ECO mode somehow caused no fan usage at all, causing repeated PSU overheats, lowering the effective capacity to where it could no longer power the system. But that's just my guess. BTW...EVGA was great with the RMA process.

if you have a local store with PC parts near you, you could probably ask them if you could get one just to test and ask if they'll let you return after a short time.

while you could not say anything, they don't like people who do that. But if you get permission first... sometimes they are nice and let you. A local best buy let me buy and return some RAM once in this way.

Yeah this is my first time to DIY a PC. I did research and bought EVGA G. Thanks again!

Yeah, I can try. I noticed that online retailer may have a open box return fee like 15% for NEWEGG. Thanks.

In addition to what everyone else has suggested, I would also try testing everything you can individually. Going by what I've read, I would take a guess that it's either the RAM, motherboard, or PSU that's causing this so testing those would be a good idea.

[Rappalores]

Have to admit stupid young me bought a 40€ 750W PSU with NO protection mechanisms and well, after not even one year it randomly shut off ect.

 

So yea, if you have a old quality PSU lying around try it out, plug out your GPU if you have to and see if that works.

No worries, it's all good.

 

Welcome to the forums!

Problem solved. I took the pc to a computer repair store and it ran without any problem there for more than an hour. Then they montioned it could be a surge issue. So before they run a whole test, I took it home and bought an UPS for it. It worked like a charm for almost a week. Although I had a fancy surge protector outlet, I guess it only protects the high wave? But in my case it is the low point that caused the issue.

Thanks to everyone who replied!
