pc keeps turning off by itself.

[Joshua Ondangan]

Hi I decided to gift my daughter my old pc and the other day or was it yesterday I keep having this problem where it works but after 16-18min it restarts the system. I do get single beep which sounds good and so far no other problem besides that. so decided last night to remove everything else from the case while keeping the motherboard inside. around 20-30min ago I just finished rebuilding it and at first with 3 ram it started but no beep no nada but just kept itself turned on so I turned it off and I decided to just slap 1 ram on it and since then whenever I turn it on (it says on for a 1 second or less) then immediately turns off. the system is custom liquid cooled and so far just letting the pump push around the water it's fine and no leak.

everything else was working fine a month ago before I took the ram and split it among my htpc and this current pc (this one used to have 4gb only) since I built myself a new one and this was just collecting dust in the corner so yesterday since having that ram problem this kinda happened in the end.

I've had this one since mid or late 2011 can't remember much lol and so far it was going strong. btw everything turns on when it turns on just that it turns off that fast too.

 

anyone else got any other ideas I have to try as I currently have a few on the list and gonna start them now.

 

hopefully we can fix this as this is gonna be my christmas gift to my child and would be a huge upgrade from her old hand me down phenom II x4

 

System:

 

Intel i7- 3930k, MSI X79A-GD65 (8D), G.SKILLS Ripjaws Z 12GB (4GBX3) 1600mhz CL9(before disassembly was running it at 1333 cl11 or something I believe for it to work well), intel ssd 128gb, zotac gtx 780, seasonic x760 gold. windows 10 64bit

 

Problem:

 

turns off after a 1 second or less.

 

 

Things yet to try: 

 

Try a new psu (the psu of the pc I'm currently using and I'll be replying with my phone).

Try removing the gpu and see if it beeps or something.

Try a new ram?(currently the ram is working on another system and yesterday It worked on this system besides the 16-18min problem). the ram is pretty good on memtest when i tested it.

Is there any 'anti-surge' message on the screen, after the reboot?

It looks like dead psu. Try replacing it with something else and see if this problem occures again. I've had such issues on couple old systems.

Maybe a bad PSU? Maybe something shorts out and psu cuts the power? Happened to me 2 days ago. If you have no other working PC to test all the components, then you're out of luck.. Trial and error my friend. You're saying it was going strong and then just started turning of? Do a clean Windows install and see if the problem remains. So you know if the components are okay. Get new Ram sticks and try if it works.. Try different ram slots.. I hope I'm not being to usless haha

I'm not sure if this can be a software problem, because modern windows versions detect that kind of staff and tell user, that something's wrong. Actually, a friend of mine had this issue too, but it was not that frequent. He tried everything, even built a new system. After that it was 100% clear, that it was bad psu.

Start with PSU then. Good luck with repair, hope your daughter likes it

Thanks, but I'm not a topic starter.

Hmm I found this on the psu connector for the cpu. the one that connects directly to the psu. so far i was planning on slotting the m12ii 520w to see but somehow after trying to connect the cpu cable to my psu i kinda saw that. i doubt its supposed to be like that. isnt it supposed to be on the 2nd pic where you can see the white pc.

Edit: ill still snoop around and see any other possible problem. its just psu then it is cheaper. hoping it didnt affect the motherboard

[Joshua Ondangan]

Ok now tried it with the m12ii evo 520w osu from seasonic. it lights up and all but so far no post or beep. maybe its ram ill try another stick. also used a different gpu a hd7850 since i dont hve a psu connector that fota the m12ii evo unless i dig around my storage

Looks like a psu problem but somehow mo post or beep with another psu (possible to be ram? i got no other ddr3 ram available besides those 3 and another one which is the same as them. but all those ram including the red ones work on the white pc

 

 

edit: for now I managed to make it work with 1 ram on the far left ram slot. so it's running at 4gb ram on a single stick. so far the cpu connector just got blasted but I'm not sure if the psu was taken with it. I'll try the psu on another pc and see how it goes. if it works then I'll just have to use the other cpu connector I have if not then guess new psu on the to buy list. possibly another set of ddr3 ram since I'm having a lot of trouble putting more than 1 stick.

Maybe a faulty ram slot.

Cpu connector blasted? U mean, it had actually exploded? This is insane.

Yeah the cpu connector connected to the psu actually has a melted pin and a semi looking melted one.

 

I have a spare cpu connector that came with my psu the 12pin one if i counted right. so far its alive. altbough 2 ram stick worked and its 8g. I guess 8gb js good for my daughter. her old one got 4gb (less than 4 since she use 32bit os)

 

Edit: now i just have to fix the cables and plug psu in the right spot. so it would look better but sadly i suck at cable management hahahaha

It's the cable that directly goes to the psu (its a cpu connector).

 

so far everything works fine now and my lass would be happy with it. I plan to box it and wrap it with gift wrap. hopefully nothing bad would happen since I manage to reuse the old seasonic x760 psu.. but I'm sure she would love the performance difference compared to her old pc (which used to be mine too back then hahahah).

it also seems the ram is kinda faulty but they work on the white pc I was testing on but anyways manage to make 2 stick worth for a total of 8gb should be enough to satisfy her.

 

edit:sorry picture is not amazing was using my samsung e5 camera.

thank you btw for sticking up with me during my ordeal @paprikman

So, it's just a ram. I would try some other sticks anyways, just to make sure that it's not a faulty ram slot. I hope that all connectors on mobo are ok tho.
