Windows 7: BSOD when returning from sleep and sometimes randomly. 0x000000E1

GingerBreadDude · 03 Oct 2012

Says Worker thread returned at bad irql

There were 4 or 5 codes but these are the ones I wrote down
0x000000E1
0xFFFFF80003BCB610

Happens most of the time when I return from sleep, but not always and sometimes it happens randomly.

Anyone know how to fix it?

Thanks

Welcome

Problematic software:

Code:

Start Menu\Programs\McAfee	Public:Start Menu\Programs\McAfee	Public

Please uninstall McAfee, it's a known cause to BSODs

I and many members on our forum recommend Microsoft security essentials with
a great combination of Malware Bytes.

→ Microsoft Security Essentials - Free Antivirus for Windows
→ Malwarebytes - The Free version
→ Good and Free system security combination.

Run a full scan with both (separately) once downloaded, installed and updated.

In addition, Run this tool and delete anything it finds:
→ Anti-rootkit utility TDSSKiller

Code:

Run the system file checker for repairing corrupted windows files
→ SFC /SCANNOW Command - System File Checker

Run disk check
→ Disk Check

You also need to free your start-up, keep nothing except your antivirus
→ Startup Programs - Change

Let us know the results

Uninstalled McAfee cause it was a quick process and haven't been able to get to the rest (been busy) but so far no BSOD, I'll finish the rest of the procedures later today and get back to you.

Thanks

**koolkat77** · 05 Oct 2012

Sure
Take your time

GingerBreadDude · 09 Oct 2012

After uninstalling McAfee alone I have experienced no more BSOD. Tdsskiller found nothing. Updated my drivers and all. Thanks for the help! I really owe you one

That's good to hear.
Feel free to mark this thread as solved when you're ready.

Good luck
