Yoga 720-15IKB BIOS Problems

My laptop has some weird problems on the lastest BIOS 4MCN31WWV2.03. Sometimes it seems that computer runs the coolers in turbo boost mode when I'm using it on battery saving mode. I'm still getting blue screens every 2-3 days, but after reboot everything works well. What should I do? Does somebody have the same issue like mine machine has? Should I go back to previous "loud" BIOS version?

My config: i7, 8gb RAM, 256 ssd, gtx1050

First thing to do is the usual "update everything." Download and use Lenovo Vantage to make sure all your drivers are up to date. I see you have the latest BIOS, so that's good. If the issue persists, use Event Viewer > Windows > System to see if an error was logged aroud the time of the BSODs. That could give a clue as to what caused it. Also helps to have any information the blue screen displayed. 

 

Next time the fans race, launch Task Manager and see what's hogging the resources.

I'd start with making sure all drivers and BIOS are up to date. See if that fixes things.

If not, make a note of what's running when you get the Bad_Pool_Header message. If it's happening with the same software running, you might want to see if there's a newer version of said software.

You can also run hardware diagnostics from Lenovo Vantage to rule out RAM issues. It's more likely to be a bad driver, older BIOS or buggy software.
