Infection: Laptop freezes about 40 min after startup
A few days ago, my Samsung Pentium laptop freezes about 40 min after startup and I had to turn off and then turn on power to get the desktop.
I deal with this temporarily by turning the clock backward. This “bug” isn’t sensitive to pm, am, and date. It’s sensitive only to hour, min, and sec. (For example, if startup time is 3am, turning the clock back to 11pm the previous date doesn’t help and this actually leads to freeze because the “bug” sees that 40 min has passed. However, turning the clock back to 1a.m. will keep the laptop working for 2 hours.)
What is causing this strange problem and how to fix this easily? Startup won’t help. I tried Avast virus scan, but this doesn’t help.
I am reluctant to do a system restore, one reason being my laptop has no restore point.
Thank you for your help
