Computer off, power light blinking

[g_goyal2000]

For my system configuration, see my signature.
I have a dekstop, not a laptop.

Yesterday, I experienced a strange problem.

My computer had been up for about 2 hours.
The internet was on and Bitlord was running along with anti-virus & firewall.
I left the computer running and took a break. I had turned off the monitor.

After about 10 minutes, I noticed the computer had shut down.
But it's power light was blinking with an interval of about 2-3 seconds.

Everything else connected to computer was off.
Even the SMPS was off & it's fan wasn't running.
When I pressed the reset and power buttons, nothing happened.
I tried moving the mouse and pressing keyboard keys but nothing happened.
I eventually had to turn off the UPS to shut down everything.

The Windows Event Viewer shows nothing related to this problem.
I have checked the power settings & everything is fine.

This problem has occurred for the first time.

What could have happened?

Come on guys...
Is there no one who could have possible explanation?????

What a strange prob.. which is ur MOBO... give some detailed specs ..

Looks like your computer has gone to Sleep or Standby mode (S3 or so state) and is unable to wake up. Try disabling Standby and see if it solves the problem. This may also be due to graphic drivers. Try updating them.

No, I don't use the standby mode (affects HDD) & keep it disabled. But even if it had gone into standby mode (which it didn't), the system power light shouldn't have been blinking.

This may also be due to graphic drivers. Try updating them.

I am using the latest graphics driver.

Since the problem has happenned for the very first time, I won't do it. But if it again occurs, I might consider it.

My motherboard is MSI K8N Neo2-FX.

At least in my laptop the LEDs blink when in standby mode. Just ensuring that Standby in Windows is disabled won't do. Check your BIOS for Power Management settings.

Well, the problem happened again tonight.
But this time, it occurred while I was working.
The computer, just, turned off as if someone cut-off the power to computer.
And the power light started blinking.

Well, it's a desktop, not a laptop. I have set no specific setting regarding power management, neither in Windows nor in BIOS.

this might b standby or hibernating ........ check it out .........

I keep standby setting disabled. But I still checked & it was disabled.
As for going in hibernation, it can't be possible & is not that.

I have put my PC in hibernation many times previously.
In case of hibernation, Windows saves the environment & shows the progress after which the computer turns off, along with power light.
But in my case, the computer just turns off without any warning or prompt or error even while I'm working. And the always on power light starts blinking.

Plz, Plz, Plz..... Help me!!!!

Doesn't look good. I had this problem two months back. Would return to find my pc in the same state as you mentioned. Had problems with the SMPS, got it fixed. Then SMPS got spoilt again, bought a new power supply unit. Finally ended upgrading processor, motherboard, RAM, hard disk

 

[infra_red_dude]

Yeah check the SMPS. Also check the power connector of the HDD.

may be some voltage fluctuation..and system turned off.

So you're saying that the root of the problem was SMPS?
But then why did u end up upgrading u'r processor, motherboard, RAM, hard disk? Did the faulty SMPS damage your hardware?

may be some voltage fluctuation..and system turned off.

I use APC UPS which has inbuilt AVR.

I'm having another problem. Could it be related to this problem?

How can we exactly say about the problem.you were not present with your system..may be any kid in your family has done something.

You continue computing your system, if in between your work it shut down, than there is some problem.

Overheating is also a cause of unwanted shutdown.

What r u, blind????
I guess u didn't read my previous posts. In my third post, I have clearly mentioned that the second time, the system turned off while I was working on it.
BTW, there is no kid in my family & no one except me in my home is awake at night at 12 am.

If system turn off suddenly without any reason, than over heating may be a cause.If possible add a extra fan to your cabinet.

Check SMPS , processor, cabinet fan.Also clean cabinet and processor fan.

Also see my last post in this thread

Well, I keep one side of the cabinet open. And BTW, it's cold here (Winter's almost "officially" here). So, overheating can't be a problem.

If only I can find out why the power light constantly blinks indefinitely after sudden "shutdown", maybe that'll help me determine the problem.

I can clean processor fan but not SMPS fan.

Ok, I've just changed the IDE cable.
Apparently, it was causing another problem which got solved when I replaced it.

I hope this problem too was due to the faulty IDE cable & gets solved after this.

congrats for having a healthy system

^^^^^^^^^

I never said my system was healthy again.

For starters, since past year, my hard disk has been making a click noise everytime I start my PC. It never happenned before that.
Secondly, something from my PC is making a large vibrating sound which gradually dies out.
Thirdly, my new optical mouse's pointer is jumping.
Last, but not least, is my combo drive which is able to read all readymade/pre-written DVD's (read software, movie, magazine DVD's) but not the DVD's burned by me or my friends.

Do u still say that my PC is healthy??

No, it's not in warranty period. Well, it sometimes read my custom burned DVD's (read 1-2 times out of 10 times).
But I also have a DVD writer, not much problem except that I can't make direct copies of DVD's. I have to copy an image on my HDD & then burn it.
