More unrequested blather from me on maintenance (I'll stop after this post. I'm really going a bit off topic)
With respect to the hardware, and to cooling in particular, I'd also remind you (if you aren't already aware) that the thermal compound used to thermally "connect" the processor to its heatsink is a known problem in Sony Playstations (at leas the "fatties" anyway), (or at least it appears to be a known problem... I've seen dozens and dozens and dozens of posts over the past ~3 years indicating that it dries out, far in advance of thermal paste used in even semi-decent personal computers for instance) so if you have the skills, you may want to replace the goo. If you don't have those mad skills, you may want to ask someone you know who does to help you or consider having it professionally serviced. I've heard from gamer types who've done the maintenance that "Arctic Blue" is a good choice, but someone else may have a better choice to share.
The point is that even when well-ventilated, if the heat in the processor can't be transferred effectively into the heat sink from the processor, it can't be wicked away by convective and/or forced-air cooling.
heat flow:
Processor => thermal paste => heat sink => internal air handler => vent => dispelled to external area
Additionally, the cooling fan may also be dirty or worn, as is the case with my computer fan (I am presently augmenting my tower pc with a real fan until I can find time to break away from work and get out to a (insert computer shop name) and buy a replacement. It spins, and it looks clean, but it spins slowly, so it's not really doing its job. If the fan,
unpowered, doesn't spin freely (and I mean freely, as in, with almost no resistance) when you use your finger to spin the blades, there's something not so right about it.
As with the thermal paste, if the air can't be conveyed outside the case, then the heat can't be effectively dissipated from the heat sink, so even with a good thermal mount, the heat sink will become saturated and again the processor will not be properly cooled.
Secondly, DVDs do wear out, and when they begin to show signs of wear, they can start to miss bits of data on the disks here and there. Some omissions are so minor a user never knows it happened, but the wrong bit can spell disaster. I'm not a PC tech and and just don't have time anymore to know "everything", so I'm not sure if there's a tool (hard and/or soft) one can use to perform testing on a DVD drive, but if there is, and if you have access, it might be something for you to consider as well (since you're having issues)
Finally, if you do happen to be an "avid gamer" type who swaps disks out often, make sure to handle your GT disk like a baby. No grape jelly, no big oily thumb prints, no scratches, no shoving disk into the slot like they and the drive were made of indestructable unobtanium, or leaving the disk lying on a table out of its case, etc.
