![]() Start by running the !analyze debugger extension to display information about the bug check. If a kernel debugger is available, obtain a stack trace. Investigate the validity of parameter 1 with !pte, !address, and ln (list nearest symbols). It may be a bad pointer caused by use-after-free or bit-flipping. Run at a lower IRQL, or don't mark the code as pageable. ![]() If parameter 3 indicates that the bug check was an attempt to execute pageable code, then the IRQL is too high to call this function. Run at a lower IRQL, or allocate the data in the nonpaged pool. If !pool reports that parameter 1 is paged pool (or other types of pageable memory), then the IRQL is too high to access this data. If parameter 1 is less than 0x1000, the issue is likely a NULL pointer dereference. General guidelines that you can use to categorize the type of coding error that caused the bug check are as follows: The cause is either a bad memory pointer or a pageability problem with the device driver code. This bug check indicates that an attempt was made to access an invalid address while at a raised interrupt request level (IRQL). This bug check is caused by kernel-mode device drivers that use improper addresses. Use the ln (List Nearest Symbols) command on this address to see the name of the function. The instruction pointer at the time of the fault. For example, if the code acquires a spinlock, or is called in a deferred procedure call. Marking code as pageable when it must be non-pageable.Calling a function that can't be called at DISPATCH_LEVEL while at DISPATCH_LEVEL.Note that bit 3 is only available on chipsets that support this level of reporting.Ġx0 - Fault trying to READ from the address in parameter 1Ġx1 - Fault trying to WRITE to the address in parameter 1Ġx8 - Fault trying to EXECUTE code from the address in parameter 1 Other commands that might be useful in gathering information about the failure are !pte, !address, and ln (List Nearest Symbols).Ģ - The IRQL was DISPATCH_LEVEL at the time of the fault.īit field that describes the operation that caused the fault. Use !pool on this address to see whether it's a paged pool. The virtual memory address that couldn't be accessed. IRQL_NOT_LESS_OR_EQUAL parameters Parameter If you're a customer who has received a blue screen error code while using your computer, see Troubleshoot blue screen errors. (It is the Intel Intel (R) Pro/Wireless 3945ABC Network Connection, (R) Wireless WiFi 4965AGN, V.N/A, A00) but I'm not sure that what I've been experiencing is a WLAN connection problem, and it says not to download unless it is.This article is for programmers. I went to the Dell Drivers and Downloads page and I found this driver that is supposed to help with Intel WLAN connection problems. ![]() ![]() I know it is a problem with one of my drivers, and I am pretty sure it is the Intel (R) Wireless WiFi Link 4965AGN but I don't know how to go about fixing it. I have looked it up and tried some of the solutions people have suggested in other forums, but none of them seem to work. It will just randomly disconnect and I can't reconnect unless I restart my computer. I don't know if this is connected to the BSOD, but sometimes my computer won't connect to my home internet. The error message it shows is "Driver IQRL not less or equal (netwlv64.sys)" Ever since I upgraded to the Window 8.1 I have been getting the BSOD everyday (sometimes several times a day) It has been getting continually worse.
