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

Update your Intel graphics drivers: http://downloadcenter.intel.com/defa...me_downloadctr

If you provide us with some more info, I can get you a link. Please follow these directions: https://www.sevenforums.com/crashes-d...tructions.html

Your Broadcom drivers are old too. Again, I need more info.

How many BSODs will it take to convince you? Let me try my hand. I have been analyzing BSODs since about January, and I can't even give an estimate on how many I have seen caused by 3rd-party anti-virus. I have seen AVG, Norton, McAfee, ZoneAlarm, Avast, Avira, Bit Defender, Kaspersky, and older versions of ESET cause them.

On contrast, I have yet to see a single BSOD caused by MSE!.

Now, since this is a free forum, you are under no obligation to follow suggestions. If you prefer, you can take all other suggestions, but before you post back with more BSODs, be sure the Avast is gone. Feel free to update the drivers, and if it doesn't work, remove Avast.

Here is the Intel graphics driver:  Intel® Graphics Media Accelerator Driver for Windows* 7 64 (exe)

Try this Broadcom driver: Broadcom.com - Broadcom License Agreement

It looks like Vista is the latest OS Dell officially supports for your laptop.

After updating your drivers, please re-enable verifier as previously requested - these are pointing to pool de-alloc failures, meaning some driver is trying a double-free on a pool block (it's already freed it before). JK is correct that most times this is antivirus, but without verifier we can't be sure. Also, verifier is not a 100% guarantee it'll catch it either, so educated guessing is required.

I've been doing system and performance analysis on Windows and Unix systems for a living for 15 years, and I concur with JK's statements .

Go to Device Manager, right-click on your Broadcom Network adapter, and select Update Driver Software. Then point it manually to those files you downloaded.

If you want, after we get these BSODs sorted out, you can try reinstalling Avast.

That sounds fair.

When you get to the Device Manager 'Update driver software' screen, select "Browse my computer for driver software", and manually point it to the downloaded drivers folder.
