IRQL Not Less Or Equal on Shutdown

  Eargasm 12:29 29 Jan 2011

Hi All
Toshiba laptop a200 running Windows 7 Pro ( 32bit) Laptop runs fine until i shutdown when it blue screens with IRQL_not_less_or_equal, there is no dump file created. The next time i restart i have to choose start windows normally and everything works fine until the next shutdown.
I have updated all the drivers, but the problem persists.
I have noticed if i start the computer in safe mode then shut it down it closes without problem anyone any suggestions ?

Possible causes are faulty hardware, ie memory, motherboard, hard drive; software, including the Operating System itself, with missing or corrupted system files; malware, ie viruses, Trojans etc.

The simplest way of Windows 7 Memory test is by control panel and it can be done in these methods. Click the windows start option and open the control panel and select the system and maintenance icon in the control panel. After selecting system and maintenance icon pick the administrative tools and click the memory diagnostics tool option in the system administrative tool. The final stage of the process is to restart the system and you can find the errors occurring while rebooting your computer. While running the memory diagnostic test after reboot or you can reschedule it to next reboot. If your system shows any error while your computer boots it will scan and show at next booting of your system. We can also stop the process of memory test in between by pressing ESC button in the keyboard.

Also run check disk on the hard drive.

I have tried all above suggestions but still no joy, I have ran SFC /SCANNOW from a elevated command prompt but nothing was found.
The laptop belongs to a mate of mine and he has used it like this for the last 4 months,it never "Blue Screens" during use only when he shutdowns.
I did notice his 80GB hard drive only had 2GB free, i have now increased this to 13GB free using Ccleaner, could the lack of space be the cause ?
