PS3 Problem

[RACECAR]

Today I try to get on the PS3 as I usually do. When I had GT5 on and was doing a race, it just shut off on me. I tried to turn it on again, got the game back loaded up and it shut off on me again. I have no idea what it is, I haven't done anything different then what I have been and this has suddenly started happening to me. Can anyone help me figure out this problem?

Do you see yellow lights?

In good news, it appears to have been just dust. I dusted it out and it it ended up staying on and not cutting off just short of five minutes. Problem solved
