'Random' BSOD, Freezes and resets. Suddenly started.

Kewne · Feb 1, 2012

System:

64-bit Athlon processor
1GB of DDR400 RAM x2
Graphics card: NVidia of some type.
PSU: 500W
Windows 7 and Windows XP on different partitions.

----

I've tried running perfmon /report, but it says 'An error occured while attempting to generate the report.'

BSOD Dump & System File Collection app results are attached.

----

I'm getting somewhat random BSOD, freezes and resets. Most often BSOD, which usually but not always says driver_irql_not_less_or_equal - it disappears quickly so I couldn't remember the whole thing. No .sys file is mentioned.

The reason I say somewhat random, is this; Windows 7 originally seemed to have one of the errors frequently, anywhere between every 2 to 20 minutes. I'm not doing anything in particular at the time, sometimes it's just after start up, sometimes while I'm browsing the Internet, sometimes when I'm away from the computer. I've since formatted that partition and reinstalled 7 and it seems less frequent - it just lasted about an hour or an hour and a half. XP seems to last quite a long time too. Windows 7 safe mode lasted about 6 hours and then I had to discontinue the test to turn the PC off. Due to safe mode working (and originally thinking XP was working due to not having a BSOD/Freeze/Reset during the first test) I thought it was a Windows or Software problem. It seems this isn't the case though.

I did recently use Partition Manager to increase the size of my Windows 7 Partition and decrease that of my Windows XP partition which made me think it may be something to do with the partition - but I thought a quick format when reinstalling Windows would've taken care of that.

I've run RAM checking tools (Can't remember software and since lost in format) and hard drive checking tools (SeaTools).

Any ideas what this problem may be and how I'd fix it?

Your display card driver is rather old; it is also pre-Windows 7 and probably the reason for your crashes in Windows 7. Update the display card using the following steps.

Download the latest drivers for your display card(s) NVIDIA DRIVERS 285.62 WHQL
Click Start Menu
Right Click My Computer/Computer
Click Manage
Click Device Manager from the list on the left
Expand Display adapters
Do the following for each adapter (in case you have multiple display cards)
- Right click the adapter
- Click Uninstall (do not click OK in the dialog box that pops up after hitting Uninstall)
- Put a tick in Delete driver software for this device (if this option is available, otherwise just hit OK) and hit OK
Restart your computer after uninstalling drivers for all display cards
Install the latest driver for the display cards once Windows starts

Alternatively:

Login as an adminstrative user
Download the latest drivers for your display card(s) NVIDIA DRIVERS 285.62 WHQL
Click Start Menu
Click Control Panel
Click Hardware and Sound
Click Device Manager (the last link under Devices and Printers)
Expand Display adapters
Do the following for each adapter (in case you have multiple display cards)
- Right click the adapter
- Click Uninstall (do not click OK in the dialog box that pops up after hitting Uninstall)
- Put a tick in Delete driver software for this device (if this option is available, otherwise just hit OK) and hit OK
Restart your computer after uninstalling drivers for all display cards
Install the latest driver for the display cards once Windows starts

Once you finish updating your video driver, please take the time and install your Windows updates. You have zero installed.

Learn how to install Windows 7 Service Pack 1 (SP1)

Kewne · Feb 1, 2012

I will do both - thank you for your advice.

I do not believe these would be the problem though. Before my re-installation of Windows 7 it was fully up to date and my graphics card driver had been updated within the past 3 months.

writhziden · Feb 1, 2012

After you update the graphics card and update Windows, post back any new crash reports. New crash reports would indicate possible reasons why it continues to crash even when everything is up to date.

Kewne · Feb 1, 2012

Will do - I've just had it do a random freeze, is there anything I should post after that? Or will it not notice it, since I'll just be resetting.

writhziden · Feb 1, 2012

If you post the crash reports after a freeze, it may have relevant information. We will have to see after one happens whether the new information is useful or not. The crash report outlined in http://www.sevenforums.com/crashes-debugging/96879-blue-screen-death-bsod-posting-instructions.html includes application and system logs so we can determine if any errors occur or reoccur.

Kewne · Feb 2, 2012

This is after a reset (possibly a BSOD one - I was away from the PC so I don't know for certain) and also after a freeze.

I'm not sure why it claims in perfmon that I've not got an anti-virus - it did come up with that warning yesterday in Action Centre, but I've since installed one and the warning is gone.

I've no idea what 'Unknown' is in hardware. It was there long before the problems started too.

Kewne · Feb 2, 2012

Attached images of my BIOS screens, in case they're helpful at all.

writhziden · Feb 2, 2012

You should find the device associated with Unknown before proceeding. To determine this, get its hardware ID from Device Manager using the following method. Post here and we will help you track down the hardware and its drivers.

Click Start Menu
Right Click My Computer/Computer
Click Manage
Click Device Manager from the list on the left
Right click the Unknown device and click Properties
Go to the details tab
Change the property to Hardware Ids
Post each Id on here.

Alternatively:

Login as an adminstrative user.
Click Start Menu
Click Control Panel
Click Hardware and Sound
Click Device Manager (the last link under Devices and Printers)
Right click the Unknown device and click Properties
Go to the details tab
Change the property to Hardware Ids
Post each Id on here.

After some searching, I believe it may be a gameport. At least I'm seeing quite a few people having the same unknown device, then disabling gameport in BIOS and it disappearing. According to this post on a different website, Windows dropped support as of XP-64. I can't see any drivers for it on the CD or website either.

writhziden · Feb 2, 2012

Are you able to disable it in the BIOS? Does that provide any more stability, or do you still experience crashes/freezes?

Kewne · Feb 2, 2012

There's no option to disable it in BIOS. It's not caused a problem before though - it was there before the BSOD/freezes started.

Caused by your graphics card; hardware related. Other possible causes are Memory problems... Viruses... Corrupted hard disk file system... Corrupted System Files... Lack of Windows updates... Drivers...
Thanks to JMH for helping with my understanding of this crash.

We will start with the common problems first (see bold possible causes). Do the following steps and test after each to see if stability increases (the memory tests you can run concurrently as they will not increase stability unless you are forced to move modules around). Post back your results after each step, and if you get a blue screen crash, upload the files again and await further instructions after we are able to analyze the crash.

If you are overclocking any hardware, please stop.
Run Disk Check with both boxes checked for all HDDs and with Automatically fix file system errors checked for all SSDs. Post back your logs for the checks after finding them using http://www.sevenforums.com/tutorials/96938-check-disk-chkdsk-read-event-viewer-log.html
Run http://www.sevenforums.com/tutorials/1538-sfc-scannow-command-system-file-checker.html up to three times to fix all errors. Post back if it continues to show errors after a fourth run or if the first run comes back with no integrity violations.
Download and install the appropriate version of HWINFO: HWiNFO32 for 32-bit Windows 7 or HWiNFO64 for 64-bit Windows 7 to check hardware temperatures by running in sensor-only mode.
Use FurMark: VGA Stress Test, Graphics Card and GPU Stability Test, Burn-in Test, OpenGL Benchmark and GPU Temperature | oZone3D.Net to test the graphics card GPU. Then use the |MG| Video Memory Stress Test 1.7.116 Download to test your graphics card memory.
Run http://www.sevenforums.com/tutorials/100352-hardware-stress-test-prime95.html to determine any hardware problems. Run all three tests for a few hours each. If you get errors, stop the test and post back here.
Run the boot version of Memtest86+ paying close attention to Parts 2 and 3 of the tutorial. Also, in case Memtest86+ misses anything and comes up with no errors, run the extended version of the Windows Memory Diagnostics Tool for at least five passes. These you may want to run overnight since they take a long time to complete (run them an hour before bed each of the next two nights and check before going to sleep that they are still running).

I've done this and it showed no errors. Where can I find the report?

Proceeding to do this now - I've just installed Win7 on a completely different hard drive and had the same error before finishing setting up though, so this seems unlikely.

Download and install the appropriate version of HWINFO: HWiNFO32 for 32-bit Windows 7 or HWiNFO64 for 64-bit Windows 7 to check hardware temperatures by running in sensor-only mode.

It is unlikely, but I have seen it happen once or twice. Usually it only happens when people are using automated optimization programs.

Doing so now

Alright, let us know the temperatures at idle and during stress.

Kewne · Feb 2, 2012

Attached images of results when idle and stressed (running Burn In test - 100% processor, 1.4/2GB RAM used according to Performance in Ctrl+Alt+Del).
Currently waiting for the computer to reset on me as I couldn't run the sensor program in Safe Mode so trying to be quick by using an image.

Burn in test seems to be running okay, apart from a rising temp.

writhziden · Feb 2, 2012

Let us know what the temperature maxes out at or what it is at when the computer resets, whichever comes first. Temperatures look good in the post, by the way. Nothing too high.

Kewne · Feb 2, 2012

|MG| Video Memory Stress Test passed - all okay, with a couple of not compatibles.

Will see what temp the burn out test maxes out at now.

EDIT: It seems to level out at 73 degree Celsius max. It didn't reset while doing that for 15 minutes.

Kewne · Feb 2, 2012

Regarding Prime95 - is it okay if I use safe mode? It's almost certain to freeze or reset before three hours are up if not.

'Random' BSOD, Freezes and resets. Suddenly started.
