Windows 7 IRQL_not_less_or_equal

I brought it out of sleep mode and it crashed. Really, that's all that I can say. Hit power button. Saw login screen for just a moment [I think? It's all a blur!], then the bluescreen. I attached all the relevant files listed in that sticky thread, I believe. I've been having issues with my wireless adapter lately but I can't find a newer driver version...if that info matters *shrug*

Memory corruption probably caused by a driver. please run these two tests



1-Memtest.

*Download a copy of Memtest86 and burn the ISO to a CD using Iso Recorder or another ISO burning program.

*Boot from the CD, and leave it running for at least 5 or 6 passes.

Just remember, any time Memtest reports errors, it can be either bad RAM or a bad motherboard slot.

Test the sticks individually, and if you find a good one, test it in all slots.



2-Driver verifier

I'd suggest that you first backup your data and then make sure you've got access to another computer so you can contact us if problems arise. Then make a System Restore point (so you can restore the system using the Vista/Win7 Startup Repair feature).

In Windows 7 you can make a Startup Repair disk by going to Start....All Programs...Maintenance...Create a System Repair Disc - with Windows Vista you'll have to use your installation disk or the "Repair your computer" option at the top of the Safe Mode menu .

Then, here's the procedure:
- Go to Start and type in "verifier" (without the quotes) and press Enter
- Select "Create custom settings (for code developers)" and click "Next"
- Select "Select individual settings from a full list" and click "Next"
- Select everything EXCEPT FOR "Low Resource Simulation" and click "Next"
- Select "Select driver names from a list" and click "Next"
Then select all drivers NOT provided by Microsoft and click "Next"
- Select "Finish" on the next page.

Reboot the system and wait for it to crash to the Blue Screen. Continue to use your system normally, and if you know what causes the crash, do that repeatedly. The objective here is to get the system to crash because Driver Verifier is stressing the drivers out. If it doesn't crash for you, then let it run for at least 36 hours of continuous operation (an estimate on my part).

If you can't get into Windows because it crashes too soon, try it in Safe Mode.
If you can't get into Safe Mode, try using System Restore from your installation DVD to set the system back to the previous restore point that you created.

Oy...well, before that, I want to mention that I've manually installed two RAM sticks from Crucial. You can see them in the CPU-Z tabs. I also moved my original RAM stick to a different slot for a reason I don't remember. Do you think one of them might be slightly loose? Or that maybe the two RAM sticks I bought don't get along with the third stick? I'm basically trying to avoid finding two blank DVD's...I'm a college student without a way to get to a store for some days at the moment.

Personally I'd remove the odd stick of ram. Ideally your RAM should be matched. Same Manufacturer, Type, Model, Size, Batch, Timings, Etc. Preferably bought as a matched set.

DriverVerifier is a windows utility already on your machine so no disc required.

I'm unsure whether Memtest86+ can be run from a usb just in case you had one available.
