I think i will have to give one last conclusion about the issue:
- I have been using this system with no problems for 6 months.
-Upgraded the pc to 16gb ram from 4gb ram 1 month ago. ( Played Max Payne 3 , no shutdowns)
-PC had 3 different error at the days when the maid cleaned my room in the last month 1-windows didnt shut down properly ( pc was closed when i left)
2-blue screen (not sure pc was off when i left home) 3- windows closed itself 1 hour when maid left.
When asked she said she was lifting the power surge and cleaning under it, i believe those problems were about the cable gettting loose.
Now for the first time yesterday pc shutdown while playing a game.
