Ps2 slim overheat problem SOLVED!!!!!: I too had the overheating problem where my sp2 slim would overheat and shut down by its self. Seems the longer I waited to restart, the longer I could play which would make one think it was indeed overheating. Whether or not mine was actually overheating has me wondering! Taking for granted it was indeed overheating, I took it apart and blew out the fan which wasn't actually all that dirty, as only just a very little amount of dust came out. (My fan was working when the overheating problem started so I knew my fan was good) After blowing out my fan and reassembling the case, it "overheated again".. Dang, so I again dissassembled the case, this time removing the fan and blowing out the holes underneith the fan. Yes! I noticed that a couple of the holes was indeed stopped up with dust. Thinking this was the problem, I proceeded to blow out the holes under the fan and anywhere else I could blow some compressed air. Problem solved right? WRONG!... Started my system up again and the game cut off after about 10 min. Then I started researching more and more, tried using different controllers, memory cards and basically trying switching out everything I could think of that might cause this problem, even tried a different outlet. NOTHING WORKED!.... So I decided as a last resort I would disassemble the whole thing (as I had nothing to lose at this point) and before I got too far, I noticed this little button battery that is used for memory backup. I unplugged its connector for about 10 min.... and plugged it back in. I sat my system directly in front of a fan. BEEN PLAYING FOR DAYS, HOURS ON END WITH NO SHUTDOWNS! (I have since removed the fan and still working). Don't know if my unit was indeed overheating or not, but I'm thinking it had some kind of fault that stayed in memory and removing the backup battery cleared the fault. Hope this helps out everyone that has this problem...
