Blue screen occurring over and over?

This happened on my laptop today. I was playing league on it and it shutdown (which happens most of the time if i didn't do a restart beforehand ) only this time when it went on i kept getting blue screen ( dumping physical memory ) following the "starting windows" screen
It restarts itself after the blue screen.
Only to happen again. Over and over
The laptop is lenovo z470 ideapad.been using it for about 3 years. Its not overheating. Atleast not above normal heat. Is there something I can do about it?

BIOS / System Password? (Thinkpad T440)?

I just brought a second hand Lenovo Thinkpad T440, the first problem was having a faulty HDD which I need to still replace, but one of the screws on the bottom of the laptop is completely rounded so currently can't access the internals. The second problem is I can't access the BIOS due to the system having a password which I don't know, will removing the CMOS battery for a couple of minutes remove the password so I can access the PC once I've replaced the HDD?

I just bought a new laptop (Lenovo) and I was reading the instructions when I came to the warning section?

I just bought a new laptop (Lenovo) and I was reading the instructions when I came to the warning section. It said that there was radiation coming from lasers (like when the DVD drive is open) I was wondering if there was any other type of radiation that came from the laptop and if it was harmful.Also, it said that it was bad for the battery to keep it above 70% all the time so should I let it die all the way and charge it until it hits 70% or let the battery get low then charge it to 70%

Will I be able to switch processors on my 2 laptops?

I have a Lenovo IdeaPad Z560 model (with an i5 processor) and a Lenovo IdeaPad Z570 model. Both laptops look identical. However the Z570 has an i3 rather than an i5. Would I be able to interchange them?

My laptop keeps scrolling/going down right?

It keeps going down right. When ever I click my desktop it highlights the icon in the most down right. In browsers it scrolls down on its own but not instant. My page down, down & end button seems to be fine and unstuck. I tried unplugging the mouse and it still happened. I'm using a lenovo z370 laptop. Any idea on what should I do?
