I have a Lenovo ideapad 320 with windows 10, have been using it for over a year with no issues. About 3 weeks ago, it randomly froze (screen has a static image, mouse pointer is on the screen but doesn't move when you touch the mouse, keyboard has no effect). I had to manually power down the pc and start again. Then, almost every time it started, it would either freeze again within 10 minutes or so, or spontaneously reboot. It was becoming so frequent that I did a system restore, which initially didn't help much, but after about a half day, it seemed to settle in and did not mess up for about 2 full weeks. When it started freezing/rebooting again, I did another overnight system restore, which held steady for about another 1 1/2 days with no trouble. Now it started again, and I really don't know what to do.
It is starting to look to me like a hardware issue (like bad memory or cooling issue) based on how older systems behaved. But I am reading that windows 10 has these kind of quirks, so I don't really know. All I can say is it is random and very weird, not something that points to an obvious place or pattern.
Some more data points to note:
1. It first happened when I used the built in camera to snap pictures, and was able to reproduce it.... but after the restore, it stopped for awhile and I never turned on the camera again. ***** THIS MAY be a coincidence, but I thought I should mention it.
2. It other than the camera, it seemed to be when the system was idle, no input from me, like when it wanted to start the screen saver, it would freeze instead.
3. Today, it froze right in the middle of a youtube video!! It was a podcast (mainly audio) and right in the middle of the speaker's sentence, it just stopped, the screen froze, and the speakers just made a buzzing sound.
Please, Please, Please help me figure out how to pinpoint this and tell whether it is a windows problem or a hardware problem. Is there any kind of utility that can monitor and tell exactly what happened the moment before the freeze/reboot?
Or, hopefully this may be an "obvious" problem that experts can identify based on others experience ? I know that's a long shot...but I can hope!
