Hi, My Windows 7 laptop recently started to freeze at startup: after login, the computer would freeze at the "Welcome" screen. I then used System Restore to a previous date, which resolved this issue. But now, the computer completely freezes about 6 minutes after startup, and I have to force shut down. I am not sure if this is related, but about 1/10 of my google search links redirect to various advertisement websites. Because of the nature of this issue, I was not able to run all of the tests as required in the initial post. If it helps, I know that Safe Mode works without freezing, but I wanted to inform you of this before running any tests through Safe Mode. Thanks so much for your time!
