Fan Errors, Freezes - Is My Power Source In Need of Replacement?

[Spottyfriend]

So I've started having fan errors a while ago, but I dusted my fan and they stopped... for about a week and then returned at about a 50% rate of startups.

A week on from that and I've been having freezes when playing games. The display freezes (and sometimes goes to black) but the computer stays on. When I restart it the first one or two times, the display fails to turn on but the computer turns on just fine.

So my question is, is this my power source? And if so, how can I tell?

Any suggestions would great thanks!

Insufficient detail to diagnose.

What detail do you need exactly? Heat of CPU or something?

Dear Spottyfriend,
You have the computer there. All I know is that it freezes and sometimes blackscreens. Put yourself in my shoes. I don't even know if it a Mac or a laptop or anything. Look at the links, try to take a few steps and if it hasn't resolved, give us specific detail, providing system specifications (like the description you would see at NewEgg) and any error messages.
