Windows 7: BSOD often after reboot or windows update, 0x0000008E or 50

Windows 7 Ultimate 32bit
BSOD often after reboot or windows update, 0x0000008E or 50


I've had BSOD issues with this machine for some time, it can be fine for weeks (if I leave it on) but often windows updates or just rebooting can trigger a load.


8E or 50

Also had SCDEmu.sys recently which I haven't noticed before.

Have run memtest in the past and no problems found.

Any help much appreciated.

Welcome to the forum.

Remove Avast & replace it with MSE.

Microsoft Security Essentials is recommended from a strict BSOD perspective, compatibility & stability compared to other internet security software. Malwarebytes is a great combo to MSE. They are free and lightweight.

Also uninstall your existing Antivirus software before you install MSE.

Good and Free system security combination.
