Solved BSOD when returning from sleep and sometimes randomly. 0x000000E1

[GingerBreadDude]

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:

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

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

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]

Sure
Take your time

 

[GingerBreadDude]

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
