I built my desktop recently (AMD r5 1600+Gigabyte B350M GAMING+Crucial 8GBx2 DDR4 RAM 2400MHz+Crucial 275GB SSD+Seagate 1TB HDD+Gigabyte GTX 1070+EVGA 500W power supply). In the first two weeks it worked well even when I play AAA games with all high video setting (such as Watch Dog 2) but since yesterday a wried problem started to repeat.

It suddenly stops working with screen being black, keyboard and mouse off (LED does not turn on when I press NumLock key), but CPU and GPU fans keep working. If I force it to turn off and restart it I can see the Gigabyte logo during booting but same thing happens when I log in to windows or some time after. If I turn it off and wait some time I can successfully enter the system, but the problem occurs when I do some heavy work. I believe it to be a problem of cooling but when I use the monitor software to see the temperature and fan speed they look just fine (52 ℃ CPU with 2400 RPM fan and 60℃ GPU with 2000 RPM fan, during performance test) 1 second before it crashes. It really drives me mad.. Anyone knows what happening???

Hi Vincent. Just a couple questions, What is the make and model of your PSU? Do you have it overclo9cked and if so to what point?
