what is faulty ? · DIGIT-ARC

hi guys,
i have already lost lot's of hair during this issue so i gave up and now i need some help fron u ..
8 days back in a evening i had played world of warcraft for 3-4 hrs then i shut doun my pc took rest for an hour and switched on my pc, since then the problem started. When i turn on my pc cpu and other fans spins for 3-4 seconds then the pc shutting down. That night i had tried several times but problem persist. Next morning when i switched on the pc booted smoothly and went to desktop but after 30-40 mins it shut down automaticly.(nt like power failure, it's like, when u press power botton in a running pc it shut down so quickly, pc shut down like that). I took everything off now only mobo, cpu, ran and psu is connected, switched on but same problem. Cpu fan spins for 3-4sec then pc shut down automaticly. But after a long gap when i turn on my pc it is running smoothly for 30-40 min then it shut down automaticaly like i told before and same prob happening !! Pc is nt staring cpu fan spins for 3-4 sec then it is shutting down !! Cpu temp is arround 45-50 so i thing it's nt the heat issue ..
My config is in my sigg..
So what is the prob ? Any suggestion is welcome ..

Thanks in advance.

PSU Issue or low Voltage! not sure!!

check temperatures................

Temp is arround 45-50, i think it is fine. Also i use ups so there is no chance of low voltage. Any other possiblity ?

Most probably looks like a faulty PSU. Check with another PSU. Even generic ones will do. Do remeber to take out your graphics cards.
Also check with your PSU, removing the graphics cards.

What is the condition of the heat sink over south bridge ?? That too needs monitoring..

After long gap start the PC and monitor South Bridge temhs also, it may refer as Motherboard temp in BIOS, see if that is rising or not

Ok. Now reset BIOS. If the problem continues, it is motherboard problem. Send it for RMA.

Check your motherboard mounting. See if its making any improper contact with some metail surface, causing it to short. Also check for rust build up.

Try changing RAM.

I am very sure that its your mobo's fault. I have troubleshooted this exact same problem for a friend by RMAing the mobo.

So Send it for RMA!

I've faced similar issue due to loose fuse connection of the spike gurad - so check the fuse of spike gurad/wall power socket/UPS.

1st only mobo+cpu
2nd mobo+cpu+ram
3rd mobo+cpu+ram+gpu
check like this it'll cought the problem very quickly.

Any update? @ dibya_kol?

I had sent my mobo to abacas, they checked and returned it to me and told me my mobo's problem has solved. I was very happy. I reinstalled os. No problem.
But Next morning the problem occured again. Since then the problem persist.
I don't know what to do. I am totaly lost !! And i am nt sure they(abacus) checked my mobo properly !! Or my cpu is causing prob ? It's temp is arround 45-50. I have checked psu,smps,gpu in my bro's pc. Those r working fine there.

can some one plz give/link me older vr of bios ? Something from 2011's.

^^ Check manufacturer website

just a guess but take out mobo with cpu & ram installed out of cabinet & place it on some non-conducting surface like newspaper.connect power button wire & press it to see if this issue can be reproduced.if it starts normally then leave it running for a few hours & if still no issue then post here.

Bios 15-12-2011 - Biostar TZ68K+

Again, motherboard problem for sustained period of time.

Well that bios is for 22nm cpu support. Now if u use that bios will that effect or damage my 2500k cpu ?
If possible can u or someone plz link me a older vr of bios ? Or if someone using this same mobo plz send me his/her bios ..
@top, i checked everything related power, all r fine.

did you try my suggestion?

Yes i did as u told but problem remains ..

chk this Biostar TZ68K+ Ver. 6.x Bios 726

using a 22nm cpu supported bios won't damage the 2500K ( or any ) - it will just install the support for 22nm cpus ie once you install 22nm the bios will automatically recognize and configure a 22nm IB cpu properly.

and the issue is definitely related with the mobo - send the mobo to the service center, tell them the issue re-occurred again and if possible tell them to test it in front of you.

Already checked, there is nothing in there ..

I was also facing the same problem. It was due to faulty graphics card. CPU and PS fans used to spin for some time and PC used to shutdown. When I removed the Graphic card it started properly with embeded graphic on MOBO. I replaced my Xforce graphics card with new. Now PC is OK.

My gpu,psu,ups,rams all are running fin in my bro's pc.
BTW, i sent it again to abacas. Now it is 3 times !! WTF !! Abacas survice sucks !!

if possible go to service center & ask them to show your mobo running from power off state in front of you.if it works there but not at your home then there may be some sort of shorting in your system/power line.i am assuming that cpu used with mobo at service center is yours.
