I'm having trouble getting my PS3 slim CECH-2101A 120GB to read PS3 game disc. All my PS3 games are in good condition but when I insert them into my PS3 I can hear the PS3 attempting to spin the disc but nothing shows up on the XMB. It takes me about 3 - 5 tries of ejecting and re-inserting the disc to get it to show up on the XMB. My PS3 is also a lot louder than when I first got it in 2010. I'm not sure if it's the fan or the disc spinning that's causing it to be so loud. My PS3 is kept in well ventilated area and sits on a hard surface.
Other types of disc such as CD, DVD & PS1 reads as soon as I insert them and show up on the XMB instantly compared to the PS3 game disc which takes about 30 seconds to appear on the XMB.
