    When you say crashes does it go completely off? Or does it restart itself.?


    Personally I'd bring it back to where I bought it and get them to fix it, especially if it's only 3 months old.

    Yes it goes completly off and doesnt restart at all.I thought that in Safe mode is not that problem but even in safe mode when i use it for at least 20 minutes it shuts down.
    I cant get it back becouse it was a gift from outside of the country so im stuck with it :( does anybody knows what is wrong with it ?

    It sounds like a motherboard issue, specifically bad capacitors , ok when system first on but when it warms up (literally) the caps fail causing the system to crash.

    Samuria i opened it but there is no dust becouse its a new pc.
    So you say that its becouse of the motherboard right ? I have Foxconn motherboard.When the Pc is not running during night and when i start it in the morning,is ok during 40-50 minutes than it goes completly off.When i try to run the Pc again as soon it opens the Desktop after 1 minute it crashes again.I think is motherboard or cpu heating what do u think for sure ? :(

    I think one of the parts for the CPU is overheating, not sure what it is exactly. Can you try opening your case and checking which part is the most hot and/or get a program that checks pc temperature. Looks like you bought some factory defected ones. I don't know for sure though. Checking it on your own is the best way.

    Do you have only 1 fan in your case? 'Cause that will most likely be the cause of the other part to overheat. At least 2 side fans and 1 fan inside will do. And it seems that all is doing okay except for your Temp1. I am not good at guessing which part it is so its better to catch your computer when it crash and most likely identify what part is the hottest. (Usually like touching a glass with hot coffee) After that we can identify your problem.

    Did you run with the case open?

    This behavior is typically due to overheating. Looks like the computer's graphics card overheats. Accumulated dust is often the reason for such a behavior. Clean the case from dust.

    Indeed this does sound like an overheating issue.

    I would recommend you, just like Prebenda has advised, clear out any dust from your computer, and also just to be sure, apply some thermal paste to your CPU.

    Also be sure to make sure you have no blockages in your graphics card fan(s).

    Where abouts is your computer situated?
