Windows 7: BSODs at random times

smitty831 · 08 Mar 2011

I have a 2.5 year old Dell XPS M1530 running Windows 7 Professional (x86). Vista came pre-installed and I installed my current OS a little over a year ago, and have never re-installed it.

Hello,
Firstly, McAfee needs to be removed - it is a known cause of BSOD on some Windows 7 systems. Use this removal tool when McAfee is removed: How to uninstall or reinstall supported McAfee consumer products using the McAfee Consumer Products Removal tool (MCPR.exe)

Replace it with MSE please: http://www.microsoft.com/security_essentials/

These need UPDATING:

Note

- search Google for the name of the driver
- compare the Google results with what's installed on your system to figure out which device/program it belongs to
- visit the web site of the manufacturer of the hardware/program to get the latest drivers (DON'T use Windows Update or the Update driver function of Device Manager).
- if there are difficulties in locating them, post back with questions and someone will try and help you locate the appropriate program.

- The most common drivers are listed on this page: Driver Reference
- Driver manufacturer links are on this page: Drivers and Downloads

If problem persists, do a memory test and run it for at least 7 passes (6-8 hours): RAM - Test with Memtest86+

Regards...
Dean

IRQL_NOT_LESS_OR_EQUAL (a)
An attempt was made to access a pageable (or completely invalid) address at an
interrupt request level (IRQL) that is too high.  This is usually
caused by drivers using improper addresses.
If a kernel debugger is available get the stack backtrace.
Arguments:
Arg1: 843a8020, memory referenced
Arg2: 00000000, IRQL
Arg3: 00000000, bitfield :
    bit 0 : value 0 = read operation, 1 = write operation
    bit 3 : value 0 = not an execute operation, 1 = execute operation (only on chips which support this level of status)
Arg4: 830b42af, address which referenced memory
