Used 60GB Playstation 3 Issue, need a bit of help. *Please?*

I wish I had all the answers but I don't. My girlfriend purchased a used 60GB after trading her 360 in for a Playstation 3. It was a good model, no scratches really and it looks like it hadn't been used much. The problem itself is not frequent yet every so often.

The Issue: Every so often, the Playstation does not want to play Playstation 3 games, or at the very least Call of Duty 4 or Warhawk, yet Uncharted, Assassin's Creed,and other Playstation 3 games do play. It will also play Playstation 2 games, as well as DVDs at this period of time when it doesn't want to play some of the Playstation 3 games. When you insert COD4 at this time, for example, the loading icon will appear then disappear. The disk will not be read and the Blu-ray disk icon where you would highlight your game will not appear.

The Concern: We don't really want to take backthe Playstation. We have about eighteen days or so before Gamestop will not take it back to replace for another used model. I just want to know your opinion on whether or not it's the disk drive or perhaps a glitch of some sort due to a Firmware update (It's updated to the most recent one). It's just slightly odd that when this problem does occur, that it will play some PS3 games but not others. All her games are brand new and no damage is done. They go back into their case when switched.

Thanks again guys, I just am really dumbfounded on this issue. My 60Gb on the other hand works as the day I bought it. So I have no doubts with Playstation 3, just wondering what's the issue with my girlfriends.

The problem is not happening right now, as she's playing COD4 right next to me. So weird.

Oh, cool. Well if you'd like to play with her and I it's AdamskaOcelot for her and Reule for myself. The update is the latest, I can't remember which one. Which is funny, I just told someone the update version earlier this morning. We play a lot and use mics, so just send an invite if you'd like. If not, that's cool.

Also, we traded in 360 because unlike this problem, we don't have to deal with the RROD and or paying for silly content on the Marketplace. I still have my 360, yet it's only so we can play the exclusives coming out/came out like Bioshock, Mass Effect, and Fable 2. Otherwise, her and I are more Playstation gamers.

Awesome, add us whenever. I'm on right now but I'm going to hang around Gamespot a bit to read up on some stuff. So if you don't add me soon, I'll do so later.

I think we may just end up taking it back and getting a new one. That or I'll surprise her and get a new Playstation 3. I was planning to do so anyways before she bought the 60GB but we thought we lucked out on finding one of those. Plus, like I said, we were impulsive to get one.
