Thank you for the fast response, i really appreciate your help.
I did think that it has to be a hardware error because everytime the system crashes i see a hardware related message in the blue screen.
I checked that post and point 8 caught my eye
8) Clean and carefully remove any dust from the inside of the machine. Reseat all connectors and memory modules. Use a can of compressed air to clean out the RAM DIMM sockets as much as possible.
I haven't really cleaned my pc in ages, and there is dust everywhere inside it. I'll do that right now and see if the pc crashes after that. Maybe the dust was causing the system to overheat?
Again, i'm really grateful for your quick response
