Screen flickers then shuts down
Sometimes after a couple of hours, more often than not, the iMacs screen start to flicker briefly and then the computer shuts down.
It tries to reboot and then shuts down again but sometimes it just stay dead. I have to pull the plug from the socket and reconnect it again to get it to boot.
I monitor the temperatures and the only hot part was the power-part and I use smcFanControl to increase the speed of the fans. Then I can use the computer longer before it happens, and it happens less often.
It is not a recent activity, but I want to try to fix it if its possible.
Es esta una buena pregunta?

Yes, that is correct. I have upgraded it to 4 GB RAM and a 1 TB HDD since I bought it.
