Windows 7: IRQL NOT LESS THAN OR EQUAL -- New Laptop

I just got a new laptop, the Acer Aspire 771G-9875. It's about two and a half weeks old, and tonight I got a BSOD (with name that's in the subject line) while I was just watching a video on youtube. I'll attach the SF Diagnostic Tool files.



I used to get this BSOD on a desktop I built and the solution was switching out the PSU. I think the first one was too weak, but on this, I don't have any ideas. Thanks for any help!

Welcome

STOP 0x0000000A: IRQL_NOT_LESS_OR_EQUAL BSOD Index

Please uninstall Comodo internet security. Download and install MSE Microsoft Security Essentials - Free Antivirus for Windows

Run DirectX Diagnostic Tool

DirectX Diagnostic Tool helps you troubleshoot issues with the DirectX suite of multimedia technologies that come with Windows. If you're having trouble getting game animation or a movie to run properly, you should run DirectX Diagnostic Tool to try to find the source of the problem.
To run DirectX Diagnostic Tool

• Open DirectX Diagnostic Tool by clicking the Start button , typing dxdiag in the Search box, and then pressing ENTER.

Using DirectX Diagnostic Tool to diagnose problems

Here are some of the things you should be looking for:

• Lack of hardware acceleration. Some programs run very slowly or not at all unless Microsoft DirectDraw or Direct3D hardware acceleration is available. Click the Display tab, and then under DirectX Features, check to see whether DirectDraw, Direct3D, or AGP Texture acceleration is marked Not Available. If so, you might consider upgrading your hardware. You might also need to turn on graphics acceleration.
  To turn on graphics acceleration
  1. Open Display Settings by clicking the Start button , clicking Control Panel, clicking Appearance and Personalization, clicking Personalization, and then clicking Display Settings.
  2. Click Display Settings, and then click Advanced Settings.
  3. Click the Troubleshoot tab, and then click Change Settings. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
  4. Move the Hardware Acceleration slider to Full.
• Devices are not connected. If a joystick or other input device fails to respond, it may not be properly set up. Make sure the device is present on the Input tab of DirectX Diagnostic Tool. If not, reinstall the game controller or input device by unplugging it and then plugging it back in.
• Unsigned drivers are present. Microsoft has not tested unsigned drivers for full compatibility with the latest version of DirectX. We recommend that you use drivers that are digitally signed by Microsoft Windows Hardware Quality Labs (WHQL).

Koolkat, thanks very much for your time. I've looked into dxdiag, and didn't find anything, but what you posted made me think that it could possibly be related to Nvidia Optimus (automatic switching between gpus). I heard from someone something about it being buggy at one point (he said they fixed it, but maybe they didn't), so I thought maybe it would be related to that. I've changed an Nvidia setting back to defualt.

I've also used Comodo for a long time without error, but I've downloaded MSE and I plan to try that if I get the BSOD again. Thanks again for your time and help.

I guess I'll post again if I get 2 more BSODs (1 beyond the antivirus change). Who knows how long that could be, as this one took about 2 weeks. Anyways, thanks one more time!

Alright
Let us know if you're getting more crashes.

Hi

Did you have any more crashes after the last post?
Did you uninstall comodo and keep MSE?

Let me know

Hey Koolkat,

Well, I actually got an SSD right after that post and I ended up reinstalling Windows and everything. I DID install MSE instead of Comodo . I haven't crashed again since the first time, so hopefully I won't! Thanks again!

Nice to hear that you haven't crashed since your SSD.
Do make sure you have the latest firmware for it

Feel free to mark this thread as solved, and if you have problems just let us know!
