It's been a few months since my laptop Toshiba satellite L755 (i know quite old) restarts really randomly, when I'm on YT, simple search, just logged in my account or even the windows logo showing, i thought it's ram but no ram is fine since i ran memtest for 24hrs with no heating issues too, hard disk same i used it in another laptop no issues although i have 7 bad sectors in C partition, recently i tried using a separate monitor and it worked, i don't know what it could be??
Knowing, i have i7 2nd gen processor, 8g ram, nvidia geforce gt 525m and recently updated to windows 10 it didn't fix the problem, so should i uninstall the nvidia's drivers and install is again??
For now i uninstalled nvidia's drivers and installed it again, i didn't have a reboot for now.
For the bad sectors, i ran MiniTool Patition Wizard and it found 7 bad sectors but i don't know how to know which or to block them from being used, even windows repair chkdsk /r at the beginning stops at a certain point and reboots
