Random restarts

[Marcella]

Hello, Ive been getting random restarts on my machine. I'm running windows 7 Enterprise, and I've reinstalled Windows several times thinking it may be a software problem, but it keeps happening. The latest re-install was on May 30th. I cannot figure out what is wrong. Any help would be greatly appreciated. I have included the .dmp files.

Thanks

I'm not knowledgeable enough w/ the minidump files, so can't help you there. What I do suggest is test the memory w/ Memtest86+. Download the iso and burn it to a CD, then boot your computer w/ it and let test the RAM. Test might take a while depends on the size and number of RAM installed. My past experiences w/ truly random BSOD/restarts on my and my parents' computer turned out to be bad memory.

if you can do a maleware bytes scan download for free google it I had that after doing a scan and clean it was gone .on tht note u reinstalled so that wont be problem. just suggestion . I hope its someting simple for ya bud .. if not that then u are looking at hardware prob but im sure someone will be along soon to help u with mini dumps

The minidumps don't show anything suspicious. Do you have any yellow exclamation points in the device manager? Is Windows fully updated?

 

[Marcella]

Thanks for the replies and suggestions. I have not seen any exclamation points in device manager, and since it is a fresh install, I haven't gotten all the updates done yet, but will soon. I'm now running memtest86+ and will post results when it's done.

I would follow all the above recommendations. Make sure you complete at least seven passes of Memtest86+. The more the better.

Is this a new build, Marcella? Or have you added new hardware to your system lately?

 

[Marcella]

Dawn, I built this machine about 2.5 yrs ago and the only two things I've added are a bigger heat-sink for the CPU, and a 40-in-1 card reader(which I'm removing to see if that helps). I ran memtest86+ for 2.5 hrs, and no errors after test 8. I'm going to let it run overnight, and I also reset all bios settings back to default. In memtest86+, it said the ECC was not enabled, should I enable it? Thanks.

Doesn't sound like you have RAM problem then. If there's a problem, it'll show up almost right away during the 1st pass. I happened to take a picture last month as I ran the test.

- Thanks for the pic. I'm going to run everything at default settings and see if it's a bios issue as I had it OC'd for a few days to test the machine. I may have forgotten a few settings before setting defaults. Hopefully it's just the issue with the card reader, I'll post in a few days if the problem is solved or not. Thanks so much for your help

ECC should remain disabled...

 

[Dawn1113]

I'd say reverting back to default settings would be a good idea until you resolve the problems you've been having. I'd even go so far as to clear CMOS -- which on my board is easy enough to do -- if your system had been previously overclocked. But then you may want to wait for the opinion of experienced overclockers about that. Plenty of them here and very knowledgeable, too.

Good luck!

It's worth checking the temperatures with something simple and free like HWMonitor. The only things you've changed are the heatsink plus a card reader. Maybe the heat sink hasn't seated properly and the computer is overheating when stressed? Windows 7 Enterprise? Is this a business computer running a genuine copy of Windows? I've heard that if Windows isn't properly registered the computer can shut down after a couple of hours.

I found this from Microsoft which confirms that you have to validate the OS.

Yes Marcella,
it is time to invest in a proper retail version of Windows

Thank you everyone for your replies

I have recently switched to the release preview of Windows 8. It was working fine until last week. I do understand that it is still not the official release version. However, I have been experiencing random restarts again. BSOD is caused by ntoskrnl.exe+5229d1. Minidump file included. Thanks in advance.

[FONT=verdana]Firstly, I haven't had a BSOD problem(s) in a while, so forgive me if I say something stupid.[/FONT]
[FONT=verdana]Second, I believe ntoskrnl.exe BSOD could be caused by boot.ini if it is erased or corrupted. Try booting into safe mode with command prompt and type in "chkdsk /f" without the quotation marks and wait a while. [/FONT][FONT=verdana]WARNING:[/FONT][FONT=verdana]This command erases/fixes any corrupted data on the HDD so some of your personal files may be erased[/FONT][FONT=verdana]. Then reboot normally. If the problem still occures, insert your Windows Seven CD/DVD and boot from it. Then repair your system.[/FONT]
[FONT=verdana]That's all I can think of for now.[/FONT]

Okay, the minidump is blank and because you are using a "clean" version of Windows, The problem has to be a bios setting or a hardware fault...
