I have an original CHCHA01 60GB launch model purchased around 2006 chrismas running 3.55 Kmeaw CFW since 2010. It has always ran hot but as of late, I have been noticing the screen would go blue and sound away for 1 or two seconds at random while playing backups off my Internal HDD. The screen is blue when the HDMI signal is lost on my TV which coincides with the sound going away. If I had a physical disk in, it could be compared to the game disk having scratches on it from the random freezing nature. I checked the cables and they were correctly connected. The problem is either overheating or my HDD is starting to die. I only get slow frames at times with Fifa and the HDMI disconnecting with NFS type games, both which run at 1080. GTA5 runs full speed at 720 though. I know the issue is probably more towards overheating since it is worst during summer and my dog closed the shelf where I had it the other day and the Ps3 frames nearly came to a stop. Is there homebrew to scan HDD for 3.55 to see if the disk is failing? Removing it just to check is not an option. I nearly stripped the cheap screws when I replaced the 60GB drive with a 600 GB. Also, how should I proceed about the overheating. I thought about opening it to clean and apply new paste myself before it gets yellow striped or taking it to a computer shop and have them clean and insulate it. Although the system might break from either of those. If anyone has experience with this, any advice is welcome. Bottomline, I want to keep my system working for a few more years and try to deal with the performance issues.
