Hi,
u need to go this link and follow the steps for ur pc optimizetion for better performance.

Open up de pc, to see if the fan stops turning after a while, if this happens a safety in the processor kicks in and shuts the processor down and holds it from over heating, this happens alot to pc with original intel coolers,
the fans are going bad after a while and just stop to cool the cpu for some reason.

Note, freezes can also occur when the memory is bad or the motherboard is bad.

Usualy it is bad hardware when this happens without the blue screens of death provided and made possible by the Microsofties.

This may also be a problem with your PC fans near your processor or on the CPU which may not be perfectly working because of which the processor gets heated a lot and freezes everything following which sometime it restarts too.

Also another reason would be high ram usage by running multiple applications than what the PC can support, try to use Free Ram kind of softwares.
