Random Shutting down

Last problem I had was an overheating issue with the 4870x2 which I had to reapply thermal paste to. In the last few days, my PC has randomly shut itself off after a buzzing noise has appeared (this is a video I took: UPLOADING) and upon starting up the system, it hangs at the Asus P6T blue post screen, I press TAB to view the post and I get this: BIOS photo it will not go any further than to say my memory.. when I hit DEL to get into setup it'll just stick on saying ENTERING SETUP.... and not do anything. The way I've gotten back into windows is hitting the restart button directly on the mobo and the pc will then proceed to boot into windows. When I got into windows I got this:

Problem signature:
Problem Event Name: BlueScreen
OS Version: 6.1.7600.2.0.0.256.1
Locale ID: 2057

Additional information about the problem:
BCCode: 124
BCP1: 0000000000000000
BCP2: FFFFFA800A5D98F8
BCP3: 0000000000000000
BCP4: 0000000000000000
OS Version: 6_1_7600
Service Pack: 0_0
Product: 256_1

The first couple of restarts after my PC had basically just died - it turned on for maybe 5 secs, and shut itself down.. I kept doing it sort of like starting an old motor and it got itself powered up again. The buzzing noise sounds like it could be from the PSU, or even the liquid cooling.. but I'm not sure and quite lost. Here are the specs:


i7 920 @3.8
4870X2
12GB DDR3
intel x25m SSD 80G, 1tb spinpoint, 640gb wd
Asus P6T Deluxe
1100w tagan
thermaltake spedo
 
Best thing to do is trip it down to bare minimum, unplug all hard drives and optical drives and then try and boot again, if it still freezes on post you can eliminate them as a problem, then I would remove any PCI cards and usb devices, it will most likely still freeze which jsut leaves your motherboard, ram, cpu, psu and gfx card, mostlikely your ram, then cpu, then motherboard and then lastly the psu. I would try 1 stick of memory at a time and see if it still freezes on post if it does then you will need to try and swap your cpu/gfx/psu/motherboard to find the cause.

Most likely cause is RAM, then CPU/Graphics, then motherboard and lastly PSU, this is my experience.
 
I agree with Bubba on this one it does usually go in that order.

But......

If the computer is making a horrible noise when it boots up then i would have thought that
its something with a fan that has the problem or this is just a coincidence and the bearings
in a fan have gone and a fan needs replacing in this case go back to the most orignal
causes which Bubba posted above.
 
Sounds most likely to be RAM or PSU, any chance you can borrow someone else's PSU to test it with?
Also, see if it boots using one stick of RAM at a time.
 
I don't have anyones PSU I can try no - I've already tried with 1 stick in the master slot, same symtoms... pressing restart on the mobo fixes it though, but the random power downs etc will cause it to come back.
 
Could the buzzing noise be your HD? I have had a problem in the past with a HD making a horrid buzzing noise and that turned out to be the problem. (PC had boot problems and HD was on it's way out I suspect). It sounded like it was a fan when I first heard it.
 
All my drives are less than 5 months old, all from OCUK.. had to replace my dead ones. It sounds like it's coming from the back, radiator or PSU. What could be causing a random shutdown, and it having trouble getting back up though? surely has to be power? Heres a video of the noise: http://vimeo.com/15081114 it's still processing, not sure when it'll be live.

Click to expand...

The age of your drives is a consideration but it doesn't negate them from being faulty.
The noise I heard also sounded like it was coming from the rear (the rear fan).

Having listened to your link, I'm not sure what sound I'm listening to. What is the loud sound during the first few seconds of the clip? Is that it? (or is that the CD/DVD)

It could be a fan that is worn and causing problems - try unplugging one at a time and see if you can isolate it.
Do you have any onboard fans, say for north bridge? What about GFX card fan?
Maybe the PSU fan?

At 5 seconds the camera focuses, as you can see in the image as well. The sound is the ugly buzzing noise that sounds like a drain. My drives are running fine, and the sound only occured during and before these crashes... it has gone away now, and so far everything is fine. I am sure it will return though, so I really want to get to the bottom of why the system shut itself down, and manages to screw up like that - and then gets fixed by a restart button on the mobo?

EDIT: I've tried turning off the GFX card fan, so it cant be that.
 
An update. my windows 7 forces itself onto the basic theme, and is indexing my HDD's as 5.9 which was usually a 7.x.. I checked the health with HDD Sentinel, but it checked out fine. Somethings wrong,but I'm really not sure what
 
Can you not pin point the location of the noise? If its not a fan then it can really only be either a HDD or an electrical buzzing coming from the PSU which neither should be doing.
 
The problem I'm having is that I cannot get the noise to come back, 2 days have passed now.. and everything is as it was, apart from some weird HDD readings, and windows 7 forcing itself to basic and changing its index rating.

UPDATE: Right, just powered on my system.. it took around 2 minutes in the post to read my HDD's now one is not appearing within windows, I am really tired of dieng drives, surely it cannot happen a second time. The first time I had all 2 of my internal drives fail, first 1 then the second.. I thought they were faulty, so I replaced them and upgraded... now I'm back the point where they're failing again... I'm really lost now

Honestly, can a faulty HDD cause the system to randomly power down, screw itself up as much as it has and force windows into basic theme? I should also note, I've always had to usually reboot my PC atleast once to get my monitors working in the morning.. meaning it boots into windows fine, I can hear sound keyboard and everything is on but the monitors are dead until a restart.

Yes, a faulty hdd could cause all these problems however a faulty psu could cause these problems also and could be what is killing your drives if it is under/overvolting. What is the airflow like to your hdds/
 
Well, I consider it to be good.. thermaltake spedo, the temps right now are 37C for my samsung spinpoint that's still operational, right now it looks like the WD is dead, It doesn't make any sense.. they're new drives, so far only the WD has failed should I call OCUK and see what they can do? I don't want this problem to repeat itself, I want a fix.. but it's not looking good atm. I'm not sure what I can do if its a sata controller, or the PSU
 
I just had the second HDD just dissappear on me in the OS... this one was 1tb full of valueble data so I cannot continue taking risks with having it in the PC. I just hope that it has not done any perm damage to the drive. The health dropped from 100% to 98% in HD sentinel, then went poof. I think I can safely say it's not the harddrives, as EXACTLY this has happened before... but now It's really important that I fix whatever is causing this, I do not want my SSD to die. ANY help on what could be killing my drives, and what I can do to fix it wont only be appreciated, but if it's fixed I will be more than happy to donate anything I can to you... I just really need this sorted out, and I'm tired of having to replace deing drives, and losing lots of data. I had the first drive that died backed up, but this one was too big.

PS: the External HDD which has been plugged in via USB for 3 years, on 2 different computers still operates 100% perfectly.

There can only be two things which can cause this, PSU or motherboard, most likely the PSU would cause this though. If you cant risk another drive dieing then buy a complete new PC as it will just be trial and error with swapping parts as with a problem like this there isnt really any test you can do easily.
