or it's simply overheating

^ check the temp after turning it back on

how to check temp?

hwmonitor?

suppose it was overheating, what did? the gpu? I've heard of this thing called "thermal paste" but not really know much about

everything? from the proc, mobo, gpu, hdd. Make sure everything inside is clean, especially around the fan. If you're not sure about what you're doing, just take it to the shop or ask someone's help o.o/
