Hmm similar issue with Win7 to a poster above...
I can run in Safe Mode with Networking (hence the posting on GAF), but on normal settings, all processes lock up and the laptop stops responding after a few minutes. This has been ongoing since the weekend.
I've no malware/viruses, the system is seemingly clean. There is a 55MB Windows Update that failed to install, and that I can't get to install in Safe Mode.
I have tried to recover the system to the last known good configuration, but this hasn't helped at all.
I own a Sony Vaio laptop, it's a few years old, but hasn't had a single issue until a few days ago. Any help or suggestions as to how to fix this are most welcome
