Help me !

Lately my pc is acting wierd...when i power up my pc then it boots fine and i can play games and watch movies or listen to music. But then the hell starts...suddenly after a random time in a random event ect gaming or browsing or watching movies, then the pc shuts down in a heart beat of second..it goes totaly flat line.

When i try to power on the pc then it starts and stops in a endless loop until i try and fiddle around in the case and makes bios reset and tryed to disable random hardare or power cables and plugs em back on, then if i am lucky the pc start again and it can stay on for few hours again..its russian roulette. I can see the mother board gets power or become ignited for 1 sec until it shuts down again..rince and repeat...what is wrong ?!

Everything is update and newest drivers and bios

I even tryed to run prime95 to stress test the pc for 30 mins and it dosent overheat or boots
My pc is like 3-4 years old hardware (most of it)


My pc spec:

Asus formula IV rampage
Intel 7 3820 sandy bridge 3.6 (OC 3.8 using turbo mode)
970 Sli gtx x 2 Sli
16 Gb G skill 1600 mhz ram
250 samsung evo SSD ( Games )
120 gb Intel SSD ( Windows 7 - 64 bit )
1 TB Hhd samsung
Sea sonic 1000 w psu modular.
Coolermaster case with several fans.
 
Possibly power supply or a loose power cable. Had a similar issue that sounds exactly like you described, and I tracked it down to a bad pin on the 24pin ATX connector.
 
So you had a bad pin on the motherbiard wher ethe big power connector is placed ?? i havent touched that wire in ages and suddenly it does that ?

Can it be the PSU is dying ?

When the pc shuts down then i can press the start botton and hear the whole system ignite and get ready for boot up but 1 seconds after it all dies down and shuts down again..then after 2 sedonds it starts again and shuts down again..
It keep doing that in a loop until i disconnect all usb devices and open the case where i try to unflug hardware and plugs em in again. and then i reset bios just to make sure..sometimes that works and sometimes it dosent..then i get angry and push random bottons on the board
and tryes to knock a bit on the hardware around..and if im lucky it starts again...im gona try disable stuff one by one...but is that any sighs with this boot loop ?

It does get poser so i doubt a broken psu

I had a 24pin ATX extension cable in my machine. And one of the pins on that connector was lose, so it wasn't making good contact on the motherboard. The system would run fine for days, then just suddenly power off with no warning. Getting it booted again usually involved a lot of swearing and software troubleshooting. Turns out every time I'd finally open the case, reset the BIOS/CMOS, reseat cards, I'd bump the cable, and it would work fine again. I eventually swapped the power supply and the problem went away. Then I inspected that cable and saw the burned connector pin. Replaced that, retested the PSU and it was perfectly OK.

That was my experience, so it's something I'd take a close look at on all your power connectors. Maybe swap in a spare PSU if you happen to have one.
 
I tryed to check th epower cables and the connectors in each end and nothing looked bad or burnt..atm im trying to run a default bios mode, had it OC for years..maybe the time has come when it dosent like OC anymore
 
Have you tried reseating everything?

CPU, RAM, cables, cards?

If that doesn't work, move to a very minimal setup:

1 video card
boot + game drive
1 stick of RAM

Could also be the power supply is flaking out.. or your power cord.. or you are getting dirty power to the wall plug. Is anything else running on the same circuit as the computer? Maybe a heater or something else that is using lots of power every once in a while.
 
Did that today..rearranged things and tryed other mudular power inputs ..was stable today..tbc tomorrow
 
That's a ivy bridge not a sandy btw...

Isolate the problem. Remove all un-needed components, run prime95 (or some other stress test). Check the ram with memtest , ideally 4 hours will present a problem, but I have seen it pass for 18hours then poof! A failure. Is it overheating? Does the PSU smell bad?

Overocked? If so the problem is likely there, revert to stock and test.
