Thank you for replying,
I have gone into my BIOS yesterday and saved & exited with the "LOAD DEFAULT SETTINGS" option.
When I rebooted the PC, everything seemed to be working fine. I did not have any form of micro-stuttering, but ofcourse I wouldn't let me give myself false hope.
Today I turned the laptop on again. I did have a few micro-stutters now, but for some reason it's becoming less and less occasional over time. (which is weird, a PC cannot 'heal' itself over time as for example a human body, does it? Although I have had numerous occassions that I find it to act this way......
)
Maybe it didn't "save" the fact that I resetted the BIOS settings to default? (Although I did save & exit)
I have never changed any BIOS settings before at all.
I wanted to try re-flashing my BIOS today, but it is unable to do so.
Lenovo has a list of drivers on their site, specifically designed for my laptop model. The BIOS they offer is packed inside a flash utility, which is simply a .exe to run. When re-downloading the version 91 exe and running it, it couldn't proceed as my BIOS is already at version 91.
So far, there is no other way to flash my BIOS but with Lenovo's own .exe utility. That is all they offer me.
However, if you had other "diagnostical" procedures in mind that we could try, I would be glad to do so. :)
(As I said, blaming the BIOS might be a wild guess)
