too many BSODs

[zficyk]

Hi,

I have been having many BSODs on my workstation, more than 10 per day. Most are #50 page_fault_in_non_paged area. They seem to occur at randomly. Ran memtest, but didn't find any problems.

I Hired an IT consultant last week to troubleshoot the system and they took out one RAM card and changed the power supply. After still having many crashes, they suggested I format the system and reinstall windows.

Formatted, and reinstalled Windows yesterday, but I'm still crashing. Here are the minidump files from the last two days. I haven't saved the old ones before formatting, sorry.

Since the IT consultant was simply looking up your forum, I decided to go straight to the experts. Please help before I take a hammer to my computer.

Hi and welcome

These point to memory management. It could be either the memory itself or a driver.

Please run these two tests to verify your memory and find which driver is causing the problem.


1-Memtest.

*Download a copy of Memtest86 and burn the ISO to a CD using Iso Recorder or another ISO burning program. http://www.memtest.org/#downiso

*Boot from the CD, and leave it running for at least 5 or 6 passes.

Just remember, any time Memtest reports errors, it can be either bad RAM or a bad motherboard slot.

Test the sticks individually, and if you find a good one, test it in all slots.




2-Driver verifier

I'd suggest that you first backup your data and then make sure you've got access to another computer so you can contact us if problems arise. Then make a System Restore point (so you can restore the system using the Vista/Win7 Startup Repair feature).

In Windows 7 you can make a Startup Repair disk by going to Start....All Programs...Maintenance...Create a System Repair Disc - with Windows Vista you'll have to use your installation disk or the "Repair your computer" option at the top of the Safe Mode menu .

Then, here's the procedure:
- Go to Start and type in "verifier" (without the quotes) and press Enter
- Select "Create custom settings (for code developers)" and click "Next"
- Select "Select individual settings from a full list" and click "Next"
- Select everything EXCEPT FOR "Low Resource Simulation" and click "Next"
- Select "Select driver names from a list" and click "Next"
Then select all drivers NOT provided by Microsoft and click "Next"
- Select "Finish" on the next page.

Reboot the system and wait for it to crash to the Blue Screen. Continue to use your system normally, and if you know what causes the crash, do that repeatedly. The objective here is to get the system to crash because Driver Verifier is stressing the drivers out. If it doesn't crash for you, then let it run for at least 36 hours of continuous operation (an estimate on my part).

If you can't get into Windows because it crashes too soon, try it in Safe Mode.
If you can't get into Safe Mode, try using System Restore from your installation DVD to set the system back to the previous restore point that you created.

Hi zficyk and Welcome to The Forum.

Further to zigzags excellent advice here are some older drivers that could do with updating:

e1k62x64.sys Mon Jun 22 19:05:53 2009 Intel 82577LM Gigabit NIC. You could also try the Intel® Driver Update Utility to see if it has any other newer drivers for you.
I tend to find it works better when I use Internet Explorer.

iaStor.sys Fri Jun 05 02:53:40 2009
iaStorV.sys Wed Apr 08 17:57:17 2009 Intel Rapid Storage.

RTKVHD64.sys Fri Jul 10 11:23:45 2009 Realtek HD Audio R2.64

atikmdag.sys Thu Jul 30 04:33:27 2009 AMD Graphics Drivers

• Download and install Driver Sweeper.
• Uninstall your current Graphics setup through Programs and Features
• Boot to and run Driver Sweeper in (preferably) Safe Mode to clean up the remnants of your current Graphics set up.
• Reboot to Normal Mode.
• Install your new Graphics set up.

HTH.

Thank-you for the quick replies.

I'm pretty sure it's not the RAM since I've run memtest overnight a couple of times and no errors were found.

I'll try updating the drivers.

Thanks again,
