Windows 7 crashes - monitors go on standby

Hi,

Problem

• Windows 7 randomly crashes
• My 2 pc monitors that are connected, simply go on standby
• The computer appears to still be running, as my external hard drive is connected with the light on.
• In order to get my PC back, I need to force a restart, by holding down the power button on the tower unit.

If anyone can help me solve this once and for all, there will be more than just eternal gratitude offered.

This is beginning to drive me up the wall. I got my PC back from repair last night. They replaced the motherboard as they thought this is what was causing my problem. Unfortunately not.

Now, I'm no computer genius - the web is more my forte, but I've managed to get a little bit of info from the event viewer.

If you guys need me to provide any more information, please let me know.

With hope and thanks,

Hi,

Please follow these instructions: https://www.sevenforums.com/crashes-d...tructions.html

Attach the .zip file to your next post in this thread.

I've attached what I was asked to, and included the perfmon report in the same zip as 'perfmon_report.html'

Many thanks for all this assistance.

My windows 7 info is:

• Windows 7 Ultimate 32 bit
• OEM version
• Not entirely sure of the age of system hardware, but I'd say about 12-18 months.
• OS was installed about a month ago.

As ever, any help is much appreciated.

Firstly - please don't apologise. You're helping me out in a big way - so there's absolutely no need for an apology. I'll patiently await your next post.

Ok.

Do you have a Belkin USB wireless deivice?

Code:

 08/01/2007   17:22:53  "C:\Program Files\Belkin\F5D7050v3\VistaDriver\netr73.sys"

If so, it needs updating - Belkin : Support

Also, given that your problem showed itself in the display suddenly going blank, your graphics driver is worth an update too:

Code:

19/11/2009 nvlddmkm.sys

More up to date version here - NVIDIA DRIVERS 258.96 WHQL

That being said, the lack of BSOD dump files (which we often see with Kernel Power errors) and the fact that there is not much trace of the crashes in the Event Logs or WERCON either makes me think that this may be hardware related.

So, run the following hardware tests aswell

Video Card - Stress Test with Furmark

RAM - Test with Memtest86+

sorry for the delayed response - yes, I do have a belkin wireless adapter. Do you think this could be doing it?

not sure if this info is of any use to you - but as i clicked on the download on nvidia's site - the pc crashed for the first time in about 5 hours.

Anyway, I restarted, downloaded the nvidia drivers and am in the process of installing. I'll keep you posted. Once again, thanks for all the help today.

I'm doing a stress test at the moment, but the screen has been the same for quite a few minutes now. Where is the outputted result that I can attach to this thread?

It is 2007, you should definitely update it as suggested. Update your drivers and if more crashes, attach the .dmp's.

When you do the RAM test, make sure you run it at least several hours in a row and without interrupting the process. Report your results.

since updating the drivers, it seems like it may been fixed. But I don't want to jinx anything. I'll keep you guys posted.
