Windows 7 Ultimate SP1 Every so often; 3 days-2 weeks; I get a BSOD relating to: DRIVER_IRQL_NOT_LESS_OR_EQUAL latest minidump file: https://skydrive.live.com/?cid=e6a12ad0af374b24#cid=E6A12AD0AF374B24&id=E6A12AD0AF374B24!125 I have done MemTest I would be greatly appreciated if you could help.

This type of error points to following cause 1. Hardware problem (Have you memtest several hours for say 10 passes? Test your hdd by hdd vendor diagnostic tools. 2. Remove temporarily your antovirus/antomalware programs ( use vendor's removal tool) 3. Double check drivers. Be aware that notebook vendors have specific (adapted) drivers. (For test purpose disable driver checking by F8 when system starts.) 4. If nothing helps, reinstall and after vanilla plain operating system installation, install chipset -> video -> audio -> NIC drivers, then do updates (follow the system "request"). Operate system for some time and when the BSOD apperes, chances are that there is problem with another hardware (possibly motherboard, videocard,...) Regards Milos

Okay I'll try all of those and i will post my progress; or if i get another Blue Screen. Step 1 done, no problems. Also how would I double check drivers?

Hi , Error 0x1E was reported in the dump file. You can check following: 1. Whether you have installed updates or drivers before this happened? 2. Scan your computer for computer viruses. 3. Update all your drivers 4. Test the issue in Safe Mode to check whether this issue is related to the hardware. Regarding the BSOD error code 1e, you can refer to Bug Check 0x1E: KMODE_EXCEPTION_NOT_HANDLEDTracy Cai TechNet Community Support

Hi,it is hard to know when it started happening as I installed all drivers and updates for windows on the same day; I built my computer myself. I have scanned for viruses and all of my drivers are up to date. Also it is really hard to test this error in safe mode as it very hard to recreate and is seemingly very random.

Hi , Since the issue occurs after installing the drivers and updates, make sure that they are all compatible with Windows 7. This BSOD is probably caused by the drivers, thats why I suggest you test the issue in safe mode. If the issue does not occur in Safe Mode, the cause can be the disabled hardware drivers. You may narrow down the causes in Device Clean Boot. Device Clean Boot ================= 1. Click Start, type "devmgmt.msc" (without quotation marks) in the Search bar and press Enter. 2. Expand "Sound, video and game controllers". 3. Right click on your sound card and then click "Properties. 4. In the dropdown menu of Device Usage, please choose "Do not use this device (disable)" and click OK. 5. Please use the same method to disable other dubious hardware such as: internal modem, network card and CD-R drive. Please note some devices such as video adapter are not available to be disabled.Tracy Cai TechNet Community Support

The sound card and network card is built into the mobo. The mobo is also windows 7 compatible so I don't think it could be those. The CD-R drive though, I'll check that cause it is quite old.

James Please post a copy of your dumpfile as a shared file to your Sky Drive with a link here. http://social.technet.microsoft.com/Forums/en-US/w7itproui/thread/4fc10639-02db-4665-993a-08d865088d65 For advice on how to configure your system to create dump files please read: http://support.microsoft.com/kb/254649 The dumpfile will be created at c:\windows\minidump. You may need to change your settings in Windows to be able to see the file. To show hidden files type Folder Options in the search box above the Start button and select View, Advanced Settings and verify that the box before "Show hidden files and folders" is checked and "Hide protected operating system files" is unchecked. You may need to scroll down to see the second item. You should also make certain that the box before "Hide extensions for known file types" is not checked. What is your computer make and model? If not a branded computer what is your motherboard make and model? Type System information in the Search Box above the start Button and press the ENTER key. What is your BIOS version and date? Hope this helps, Gerry
