Windows 7: An annoying BSOD(IRQL NOT LESS OR EQUAL)

14 Dec 2014   #1

Windows 7 Pro X64

Hey I recently built a PC its all working great once I get to the windows login screen.

There are only two times I get a BSOD.

On bootup at the windows loading screen. It will simply hang for a while then I will get a IRQL NOT LESS OR EQUAL. A simple restart a few times and it will load in correctly and all will be fine.

The only other time I have seen this BSOD on this PC was when I put the PC in sleep mode and it randomly woke its self up with the same BSOD

Hellow Twig, Welcome to Sevenforums!

It seems the problem driver is part of Intel Rapid Storage Technology

  *** WARNING: Unable to verify timestamp for iaStorA.sys *** ERROR: Module load completed but symbols could not be loaded for iaStorA.sys Probably caused by : iaStorA.sys ( iaStorA+67146 ) 
Lets try uninstalling this Driver all together and then Windows should populate the correct native driver.
Follow the steps below:

1. Uninstall it from Control Panel > Programs and Features.
2. Uninstall the driver from device manager:
- Right click on "my computer" icon and click "manage" on the context menu.
- In the "Computer Management" window that opens:
- Select "Device Manager" in the left pane, It will list all the existing devices.
- Expand "IDE ATA/ATAPI controllers" by clicking on the triangle in front of it.
- Select one Intel device item under it, right click, then uninstall.
- Repeat the process for all Intel items under "IDE ATA/ATAPI controllers"
3. Now restart the computer.
4. Once booted, Windows will auto configure the appropriate native system driver.
