Regular BSOD; mostly 0x01a

HI Team,

I recently finished building this PC and I'm experiencing a ton of trouble after W7 install. Any help assistance you can provide will be greatly appreciated.

Please advise if you require further information.

These crashes were caused by memory corruption probably a driver.
Please run these two tests to verify your memory and find which driver is causing the problem.

* If you are overclocking anything reset to default before running these tests.
In other words STOP!!!

* If you have a Raid update its Driver.



Memtest.

*Download a copy of Memtest86 and burn the ISO to a CD using Iso Recorder or another ISO burning program. Memtest86+ - Advanced Memory Diagnostic Tool

*Boot from the CD, and leave it running for at least 5-7 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.

Any errors are indicative of a memory problem.

If a known good stick fails in a motherboard slot it is probably the slot.

RAM - Test with Memtest86+






Driver Verifier

Using Driver Verifier is an iffy proposition.
Most times it'll crash and it'll tell you what the driver is.
But sometimes it'll crash and won't tell you the driver.
Other times it'll crash before you can log in to Windows.
If you can't get to Safe Mode, then you'll have to resort to offline editing of the registry to disable Driver Verifier.

I'd suggest that you first backup your stuff 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"
NOTE: You can use Low Resource Simulation if you'd like.
From my limited experimentation it makes the BSOD's come faster.
- 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.

If you are using win 8 add these
- Concurrency Stress Test
- DDI compliance checking

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.
Reboot into Windows (after the crash) and turn off Driver Verifier by going back in and selecting "Delete existing settings" on the first page, then locate and zip up the memory dump file and upload it with your next post.


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.

All right I might just pause until I get further advice as I'm now worried I'm making things worse...

I found another thread in this forum with this info about latest BSOD:

First time I've ever had a BSOD . Screen shows RTKVHD64.sys. So I went to safe mode. Uninstalled Realtek sound driver. Deleted RTKVHD64.sys. Rebooted and let Win 7 reinstall the sound driver.

Now that I looked at the device manager. I noticed the following. (see picture)


I uninstalled the Realtek driver and install the driver from gigabytes site for my board. Seems ok.

So I followed the same steps and uninstalled the Realtek Audio drivers, downloaded and re-installed them from my mobo's download site. Upon restart BSOD again this time with:

gdrv.sys
0x0F6

gdrv.sys is your Gigabyte Easy Saver power utility software. Remove the software. It is a known cause of crashes on some systems.

You're welcome. At least you are no longer crashing on startup, so that is a step in the right direction. Glad to see you removed the Gigabyte utilities. Motherboard utilities are not really necessary and cause problems from time to time, so we often recommend not installing them after doing a fresh install of Windows. It is good to have those off your system. :)

Let us know if you get further crashes. If not, post back in a few days how the system is responding.
