Computer turns itself off

21 posts in this topic

Got home from work tonight, turned on the rig and after a out 5 seconds turns itself off

 

Unplugged Power and in again and does the same thing.

 

There were some ugly dust bunnies in the case that I removed but still happening.

 

Any ideas?

 

Posting this from iPhone so excuse typos :-)

Further...

 

Unplugged and removed video card ... Same

Reseated memory ... Same

 

Motherboard still has power ... It has an LED that is on

 

Rig is several years old maybe it has just finally given up the ghost?

CPU...? Do you have a spare one, that would be my next step. Specially since your mobo has a power on LED.

 

Might be a good idea to reset mobo by removing CMOS Battery.

 

Is the electricity stable there? Brown outs or surges??

 

That is all I can think of on top of my head.

Could be caused by issues with the PSU or high temperatures.

 

Maybe try booting a live CD/DVD and see if that causes it to shutdown as well again, just to rule out the OS as the culprit.

PSU i would say. something wrong with one of the rails. You motherboard it shutting down to protect itself.

Dammit. July 4 tomorrow so it ain't getting fixed until the weekend.

 

Guess I need to decide if I am gonna try to fix or replace because a shop will charge to diagnose and the parts and labor to fix. Sigh

 

Old computers are like old cars. Always breaking down.

 

Smarty... Power is stable. CMOS reset did nothing.

 

Guess I am off to the repair shop Saturday AM

Do you get a blue screen of death?>?

if so look for a program called "who crashed" that will give you a break down of the causes,

 

I had a similar problem, {but lasted more than 5 secs before dying} and it was my heat sink on CPU, if you have a spare tube, no harm in trying that.

Also may just be time to clean off the old paste between the CPU and heat sink on it and replace with some new stuff. Has done the trick before.

This definitely sounds like PSU or hardware problem to me, but I would start with Shuqi's recommendation.

 

Rule out the OS.

 

I've learned that Windows needs to be re-installed every so often to work out kinks that occur within the OS over time, but that does not seem like the problem here. Still a good place to start.

Sounds like the PSU to me as well (internal PSU breaker protection or surges causing your MB/GPU to protect itself.

 

Had the exact same thing once happen to me. The good news is PSUs are readily available, inexpensive and easily replaced.

Have you checked to see if your cpu is hanging off? (serious question) haha

 

Sounds like PSU - although I did have something similar with my southbridge overheating on my old rampage extreme 2...

Far too busy with the 4th yesterday, planning on playing with this tonight.

 

Doubt it's the OS, doesn't have time to even load the OS in the 3 seconds that it lives before shutting off power.

 

Kids desktop isn't put back together yet, so tonight going to put my drive in that box and power it on and see what happens. If it boots, that pretty much only leaves the power supply.

I am in agreement with the CPU overheating. Normally it is due to a CPU fan failure or just not enough circulation through the CPU's heatsink. Check the fan's cable to make certain it has not come loose and clean out the dust and garbage attached to the heatsink.

Well, put it in to get looked at and the verdict is that it's a short on the motherboard.

 

Bad news: Hadn't planned on spending $1000 on a new computer right now.

Good News: I get a new computer right now.

 

After poring through the notes in the "I might be building a new rig in the near future" post, decided on this:

 

Gigabyte GA-Z87X-UD4H Socket LGA1150 ATX Intel Mobo

Intel Core i5-4670K CPU

Corsair H80i Liquid Cooler

8GB RAM (almost went 16, but my research indicated minimal performance differences between 8 and 16 on Windows 7 Home)

1TB HDD

EVGA GTX 650 1GB Video Card

Corsair 600W PSU

Blu-Ray Writer

 

About $1100 including sales tax

 

Should have it Friday night and then starts the long winded process of getting everything installed again ...

Yeah, I know, I was going to try to squeeze in an SSD - but maybe I'll ask Santa Claus for that and do the reinstall thing again then.

 

Considering this was an unplanned expense, getting an SSD would have pushed me over my budget. It's something I can always add in later :)
