Windows 7: Random BSOD's during "Starting Windows"

Windows 7 Professional 64 bit
Random BSOD's during "Starting Windows"

Hi all, I have been struggling with this for some time so I will try to describe everything I've done to date. I have: Windows 7 Professional 64 Bit The hardware is under 2 years old. I have recently re-installed the OS but the trouble predates that. Since last June, I have been receiving BSOD's after the Post but during Starting Windows screen. They all seem to revolve around "ntoskrnl.exe" and my WhoCrashed program has consistently indicated its a driver issue. So I started peeling back the layers. I took out the SLI'd second video card. Still happened, I uninstalled Norton, still happened. I ran the RAM diagnostic tool, everything came back clean. It hit a spike recently and I RMA'd my motherboard. That was a week ago. I installed Windows on a brand new hard drive to mitigate variables. It worked great for 2 days then today, BAM, my first BSOD since the rebuild. This BSOD is consistent with the ones I was receiving before the rebuild. It seems to be random, I can go a week with no BSOD, and then BSOD repeatedly for the next several days. I'm slowly being driven insane little by little. I have used the UniBlue driver scanner and it tells me everything is up to date except for the Marvell Driver which is a raid controller and a controller that I have nothing plugged into. I did not install that this most recent build. Could it be a RAM problem? A BIOS issue? I am not a pro at the BIOS configuration but it doesn't "feel" like that's the problem since it consistently boots, etc. Anyway, I put myself at the forum's mercy. Thanks in advance!

Win 8 Release candidate 8400

These crashes were caused by memory corruption/exception (cx05) 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 raid update its Driver.

*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 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.

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.

So, 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/Windows 7 Startup Repair feature).

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 "Special Pool", "Force Pending I/O Requests" and "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.

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.
