Help me with BSOD

Lot's of different reasons for this set of errors (hardware and software).
Let's try using Driver Verifier to rule out the 3rd party drivers. Please follow these instructions:

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/Win7 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 "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).

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.
If that doesn't work, post back and we'll have to see about fixing the registry entry off-line.

I tried using the verifier.

After restarting my pc, it crashed before I could reach the desktop. The blue screen gave me a message similar to this.

**EDIT**
Also, this is what I got when I reached my desktop. Don't know if this can help.

**END EDIT**

"A device driver is corrupt. The faulty driver on the kernel stack must be replaced with a working version."

Unfortunately, it did not tell me what driver it was. I had to go to safe mode to turn off the driver verifier as you instructed.

I have attached the new dump file. Please help!

Driver Verifier blames ASACPI.sys as the problem. Please visit the Asus website at this link: ASUSTeK Computer Inc.-Support-
Go to the Utilities section and download the ATK0110 driver for WindowsXP/Vista/Win7 32&64-bit


Then, extract the file and execute (double click on) the AsAcpiIns.exe file in the 64 directory.
Then check to see what the date/time stamp of the ASACPI.sys file is.

The old one was: Wed May 13 21:25:17 2009
The new one should be: Thu May 14 09:26:24 2009

Let us know if there are any further BSOD's.

I would suggest removing all the Asus software as it's been known to cause problems in some systems.

Also, the P5 series of boards have been known to have BSOD issues due to memory timings/settings/voltages.
Please verify the settings required on both the Asus website and the OCZ website - then ensure that your timings/settings/voltages are the same (I wouldn't use the "Auto" setting on the P5 series mobo's if you're having problems).

Please check to be sure that the system is still set to make minidumps: Set MiniDump
Please generate the report in this post for us: SF Diagnostic Tool

Don't use the Driver Verifier again - it'll just confuse the issue right now.
Let's wait for a couple of BSOD's that we can see - then we'll see if that suggests the use of Driver Verifier.

The IRQL NOT LESS OR EQUAL error is a sign that Driver Verifier needs to be run (again).
