i have minimal experience, but here's my "dos centavos": i'd check whether some type of cooling (eg, fan) has died. could be the fan in the psu or on cpu. especially suspect overheating if the pc stays running when "doing nothing", yet shuts off when doing work. could also sniff for burnt dust odors inside the case, or sniff at any exhaust grill.
 
There's always a reason.

A cheap PSU and 3D gaming will do it. Also thermal problems with either the CPU or GPU. Driver problems, particularly with video cards.

Need specs - particularly brand and size of PSU.
