Frustrating problem.
I'm RUNNING Trend MICRO PC-cillin 2006, WINXP PRO with plenty of Ram and disk space.
My default email is through outlook express 6.
Now my problem:
If I disable SCAN OUTGOING MESSAGES SENT etc in my email antivirus options, and try to send an e-mail through outlook express (6.0) my computer immediately CRASHES with a blue screen and I get :BUGCODE_USB_DRIVER
0X000000FE etc .
This happens every time and the odd thing is that if I activate this option it works fine.
Any insights?

Why not leave it activatedI have to leave it activated or the crash happens.
I know I can and do leave it activated, but the crash is somesthing I want to silve.

ArturoWhat is plugged into the USB ports? Are there any comflicts in DEVICE manager before AND after you unplug the USB peripherals? (Don't just pull the plug, use the icon in the LOWER R corner to disable BEFORE physically removing!)

Do you ever just "pull the PLUGS" for these things?Dear sir,
I have a plantronic USB Headset in one socket and in another the Netgear Wireless adapter WG111v2 for my wireless connection.
No conflicts in device manager and I still have not tested removing the peripherals.This an update.
I unplugged the Plantronics USB headset and left the Netgear.
Really, I have to leave the netgear or else I can't send the e-mail which is the problem.
Tried again and bam, BLUE SCREEN with a NEW error:
DRIVER_IRQL_NOT_LESS_OR_EQUAL

Any ideas?Here's some reading. See what applies:
