Brand new Win 7 randomly shutting down

[FBT]

Here is the problem:

I received my new system yesterday, and it works amazing well. Unfortunately, at random times, the computer will freeze for 15-30 ish seconds, then shut down and not restart. When i restart the system, i get the option to boot in safe mode. I choose to boot normally.

I purchased the following system:
i5-750
Asus P7h55d-m Evo MOBO
GX 650w PSU
4gb DDR3 kingston ram
ATI Saphire HD 5670 512mb
Antec three hundred case
640gb WD HD
Asus ms238 monitor
and a samsung dvd player
The OS is Win 7 64bit



Since yesterday, this has happened at least 5 times. Keep in mind i was at work today, so the system really hasn't had much use. I've only had time to install my files, AVG, google chrome, dropbox, itunes 64bit, windows live mail, and office 2007.

I've updated all the drivers through the windows update and that hasn't solved anything.

CPU running at 2% and ram at 34% according the the Win 7 gadget. Temperature never exceeding 34 celcius and usually around 32.

Also, i am not getting any error messages. The computer just randomly shuts down at random intervals. Looked on google and it seems im not alone, but havn't found a solution.

Thank you,

Francois

Mmm, this is worrying as I have more or less the same rig as you even down to the same video card, and I'm experiencing the same random crashes. I'm just starting to re-install my software and every now and then the computer freezes then crashes, switching itself off. I've used the latest drivers, updated the bios stripped out anything that could conflict and still this is happening?
I've changed various settings in the bios but there's so many variables its hard to say what could be causing the problem? Having said that when everything is set to auto this shouldn't be happening?

Might have to go back?

I've gotten rid of google chrome; that didn't help.
Switched from avg 9 to 8.5, that didnt help
Now i've gotten rid of AVG entirly and replaced it with mcafee



My next step is to call the shop were i bought the system. Unfortunatly i need it for school badly and don't have time to waste having my pc over there.

Im guessing something may be wrong with the graphics card or some otehr hard drive. Unfortunatly, everyhting out there about win7 has t do with blue screens, which i am not getting.

Computer still crashed with McAfee, so i doubt anti virus is the problem.

Could it be something with the mother board?

Or perhaps my wireless adapter?

 

[jinker]

I've not got any anti virus running and switched from a nvidia 8800gt to an ati 4670 graphics card and still it shuts down? I've run prime95 stress test for an hour and it came up with nothing? Updated all the drivers and played around with various settings that might cause a power spike and nothing makes any difference. The other posts I've read suggest a memory problem but how can I tell what it is?

I've emailed ebuyers tech support to see if they're aware of any issues but as I need a stable pc this lot might have to go back at some point?

Even if yo are not getting a BSOD it will register an event in event viewer. type eventvwr in search go to windows log>application tab and check for critical errors (they have red in the left hand column) that say something like agg hang, app crash, restart, etc.

When you find them use snipping tool (built in) to make a screen shot and upload it using the attachment icon(shaped like a paper clip)

Here's a screenshot of my last switch off this afternoon.

I don't know what caused the crash?

[FBT]

I've attached mine. Seem to coincide with what is going on in terms of frequency of shutdowns. So im guessing this would be it.

Any clue?

You could chase this 'til the end of time... Bet anything it's a hardware problem so take it back to whoever you paid to build it.

Hello Welcome to SF,

This Event ID 41 is simply recording the fact that the system was shut down ungracefully. It does not provide information on the source of the problem, but just the fact there is a problem.

Lets Start with basic troubleshooting. Reboot the System in Selective Startup see whether that makes any difference. Uninstall your Protection see whether you have the same problem. It also might be the PSU there might not be sufficient power. Check these thing and lets us know how it goes.

Good Luck,
Captain

I would agree it seems like a hardware fault and in my experience probably the mobo? The CPU usually works or it doesn't, but as this is my first i5 I have no experience with these chips. The memory is on the ASUS recommended Ram list but of course it could be faulty? But, nothing showed up on Prime95 after an hour of running the cpu cores at 100%. Temps never went higher than 48.
I built the system myself trying two video cards to eliminate that problem but can't test anything else as I don't have another mobo, cpu or ddr3 stick.

Send the bits back to Ebuyer, they test them and prove nothing is wrong....what then? Something is wrong, but what do I send back?

The machine when its working is great, but then it just shuts down for no apparent reason which isn't going to do my HD any good in the long run?

Edit ***** Edit

EBuyer....think its a power supply problem? The unit is a Thermaltake TR2 RX-550PP and has not given a problem when running a Gigabyte X38-DS5 with 9450 CPU.
I'm not sure, if they're not just fishing in the dark?
Just had another reply from Ebuyer after telling the spec of the PSU and they think its the motherboard at fault. I have to apply to send it back for a replacement or refund.

Found the same problem in this thread.

Il bring the pc back to the shop. im hoping its nothing more than the mobo

Hi All,

I purchased a similar rig (exact same mobo and cpu) off ebuyer a week ago and am experiencing the exact same problem. Freezes randomly and switches itself off, although it works completely fine when it manages to stay on. There's no rhyme or reason when this happens...experienced it 10mins after switching the pc on and at other times after 8hours. No correlation with temperature either...so don't think its a CPU problem.

I've tried the following (all to no avail):
-Replaced cheap Casecom PSU I initially purchased with FSP Blue Storm
-Re-seated ATI Sappire HD4670 graphics card and updated latest driver
-Updated bios from Asus website

As suggested I'm thinking faulty mobo is most likely. I'm going to send the mobo back to ebuyer (kinda hoping it is faulty as it shouldn't be too much hassle swapping over).

If it isn't the mobo then the whole lots going back. Like win7clutz said this could be chased to the end of time.

Sorry I've not been able to provide a solution to the problem.

Cheers

I've arranged for my board to go back to Ebuyer and have re-built my old machine so can't check this.
I read today there's a black plastic cap next to the 4 pin power supply socket for the cpu that needs to be removed and an 8 pin power supply connection, connected. They even said use 2 x 4 pins connectors if you don't have an 8 pin connection?
I looked at the manual and there isn't much about or, why part of the connector is blanked out?, but the way you can check there's enough power to the cpu is to see if a red light, lights up next to the cpu socket?
I suspect the cpu won't be taking enough power from a 4 pin connector but why did ASUS cap off part of the socket if a 4 pin supply isn't enough. I'm not blaming myself if this is the cause of my problems as its an easy mistake to make
He said he was worried about frying the cpu with an 8 pin power connector connected but all was okay, and his shutting down problem disappeared. Might be something? but would advise you check this out properly first and proceed with caution before doing anything.

Obviously, if you've already connected an 8 pin supply this isn't the cause of your problem but it could have been mine. Too late to test it now but what idiot took the decision to cap off the connector if 8 pins are needed?

[RJF]

I just assumed that newer PSUs now come with 4pin power cables (P4 ATX 12v) so they plastic cap off 4 of the 8 pin connector on the mobo to avoid confusion to where the 4pin power cable actually goes. I may be wrong though and probably should've looked into it further but my mobo, like yours, is also going back and is due for collection tomorrow.

Also thinking that I also should have looked more into it being RAM related issues. I was informed by the ebuyer technician that my RAM wasn't on the i5-750 comptability list (QVL - Qualified Vendoe List), despite OCZ selling the product as being ideal for i5 and i7 processors. It also seemed to install fine after pressing the MEMok! button on the mobo.

Fingers crossed that we have been the unlucky ones and the mobos were faulty.

In the meantime, I'll post again if i'm able to shed some light on the problem in case it turns out not to be mobo related.

Thanks

I've checked the manual again and it does say to make sure you fit an 8 pin connector. Duhhh, why cap it off then? Also, like you I'm not sure my Crucial Ballistix DDR3 is on the QVL but again as the mobo is going back tomorrow I'm past caring. I guess I expected everthing just to work and didn't think to check the ASUS site for recommended memory.
But, this board is supposed to configure memory timings by pressing and holding down the MEMok button and running various tests etc, for you to eliminate memory problems. I never got any red lights which the manaual says would come on if there were any memory problems.
In fact why a machine would work for hours before switching off suggests it's more than just a simple power supply problem?
I've asked for a refund and changed the mobo spec which is costing £20 more but what the h*ll?
If you get the same problem try an 8 pin connector I know i'm going to check that out in the manual for definite.

*** Further Edit ***

Ebuyer just emailed me to say the item was faulty after all and its nothing to do with the psu, memory or cpu. Just faulty.....ohh well !!!

I have the same problem that I've been trying to solve for the past couple of weeks. I can boot into both Windows 7 64bit and Vista 32bit SP2. Under either O/S, the entire system will completely freeze and then usually shut itself off in about 20 seconds. Very intermittent. Seems to happen more under Vista.

Asus P7H55D-M EVO
Intel Core i5-750
Crucial 4Gb DD3-1600 (BL25664BN1608.16FF on QVL)

Bought from ebuyer. Older components being used:

Radeon 4670
Seasonic 300watt PSU

Running latest BIOS (0860)
Got all the latest Asus drivers
Installed 9.11.1025 chipset drivers from Intel
Disabled onboard USB 3.0 and firewire
Installed latest Radeon drivers 10.3
Installed every important update from Windows Update
Nothing is overclocked, RAM is running at 1334MHz

I've just disabled audio, the marvel storage controller and enabled Plug&Play in the BIOS to see whether that helps.

I've ran memtest86 for 12 hours and the memory seems fine. It also passed the Windows 7 memory diagnostic.

I guess the next step will be to swap out the video card and check the 8pin power connector. But it was good to find that others have had this problem.

i have the same problem with my laptop and new windows 7 64-bit and now im testing windows 7 32-bit and everything is good now no reboot in 15 hours maybe for me it's a driver problem in the 64-bit version

 

[RJF]

Connected up replacement ASUS P7H55D-M EVO Motherboard and all is now fine. No hint of a crash. Think we could be the unlucky few who have experienced faulty motherboards.
