and after a hard crash wich litteraly wos first that hard today is like 5 mins or so(experienced quite alot crashes but they were like 10-30 secs long) skype disconnected and says: unnable to connect becouse of disk Reading/writing failure. restart skype. (small crashes didn't effect skype only that big one) litteraly until i wos on win 10 i wos getting those hard crashes like 5 minutes compiuter works fine, 10 minutes crashed, and again, again same again. everythink started from the blue screen windows crash, then i could not boot, it would only show lenovo splash screen, then i left compiuter to discharge the battery and left it off all night, the other day it booted up, but in the eavning the crashes started, but at the start it were like 2 hours of normal work, and then fatal crash ( when it crashes after 2 hours it would not recover all you can do is like hard turn off compiuter by holding the on/off key or removing power supply and battery) if i turn it off by holding on/off button, it would not boot, so first time when i turned it off by the key, it didn't start and show lenovo splash screen, so i left it overnight again ( as abrove) so i turned it on on the morning, it crashed straith away just in the windows, taked battery off and disconected power supply tried again, same happened, gone to other compiuter, downloaded bootable diagnostics, wrote it to flash drive, runed the scans, everything passed tried again, same! turned off compiuter by discconecting, pressed novo button and reseted pc to orginal factory state, after all settings on, tried to download firefox and crashed again, again run the diagnostics, keeped off over night, as i turned it on today it wos quite good, but it crashes for 10-30 seconds in the morning and hard crash of 5 minutes occured recently. all my story what have i did till now
