PS3 graphics Stretching Glitch

I've been having some Graphics glitches with the assassins creed series (specifically 2/BH/Rev) and until today I assumed it was an issue with the game itself.

There are times where the textures/polygons seem to stretch out forever.

Some Reading would suggest its a heating/dust problem and could lead to the YLOD. So at this point I'm in fear for my PS3.

Two part question:

  1. How can I determine if it is a hardware problem?
  2. I'm unsure about whether to open it and clean it or not. Some people say that its too dangerous and others say it is real easy. Maybe I should stick to cleaning the vents first?

(I'm assuming cleaning it is probably good even if this isn't a hardware problem)

UPDATE :- Still happening after cleaning out as much dust as I could. I took a picture of it happening myself after only half hour: screenshot Only seems to happen with these games. So far.

UPDATE 2:- Tried my games on a different playstation and everything worked fine. I haven't found any way to fix it.


Solution 1:

It is a hardware problem if software updates don't fix it though a software update could fix it if the hardware problem was or could be cause by software use.

Make sure you have the latest system update and AC version.

Cleaning it is definitely a good idea and it isn't too complicated. The dust build-up will restrict airflow effectively reducing the amount of heat dissipation that is possible which can result in heat damage.

Unfortunately if heat damage has already limited the hardware in some way any efforts are going to be in prolonging the life and will most likely not fix anything.
