I'm hoping someone can shed some light on this very frustrating issue...
System: Win7x64 pro, 32gb RAM, Asus Z77, i7 2600k. Normally boots in less than 60 secs
Now, today it will boot to a Black Screen with a movable white mouse arrow (not a blinking cursor).
BUT ONLY if the NIC is enabled and the LAN cable is connected. If I unplug the lan cable or disable the NIC in the BIOS it boots fine. Additionally, if I leave the NIC enabled but unplug the lan cable until AFTER it boots to the desktop, I'm fine. (Thus, I can't assume it's a driver issue. Something is happening upon boot via the network.)
I've looked in the Event Viewer and can find where I have to power off the system via a hard reset and I can see errors when it boots and it sees the NIC unplugged but I can't find anything else.
Something else, it only happens on my User Account. I created another account (aptly called Black Screen) and it booted fine with the NIC enabled and plugged in.
I'm running NIS2012, updated and have done a full scan twice now.
Finally, thinking it was a startup service/program under my original user account I used msconfig to disable all non MS services and disable every startup. It still booted to a Black Screen w/cursor if the NIC was enabled and plugged in. Furthermore, Safemode w/o networking is fine but safemode w/networking has the same problem. BUT ONLY IF THE NIC IS PLUGGED IN AT BOOT - NOT AFTER THE BOOT.
Edit: updated Malwarebytes - scanned and found nothing.
Used MS Security Essentials - scanned and found nothing.
Any ideas?
