Help with PS3

Hello guys my Video Card burned down basically just one of the cap's exploded and yeah... It got messy a lot , so I decided to move to PS3...
I bough a second hand PS3 and bough brand new BF4, the second hand ps3 was working well and shit but when I removed the cd disk from inside it got serious... YLOD WHAT THE FUCK I PLAYED LIKE 5 MINUTES AND IT GAVE UP ON ME... Help will be appreciated... I opened it up since the warrant is expired since its old but everything worked fine I didn't even get the chance to unwrap the BF4 and play it... Just the moment which I removed the disk from the insite it gave me green, yellow, green, red... Everytime I start it, it's giving me green,yellow,green, red then just gives green,yellow, red... I opened it up and check like everything except the cd drive and the power supply but they seemed fine I mean everything else is like brand new, no dust no shit, btw I was the first one to remove the warrant thingy to open it up... -.-" I feel like FML THIS IS THE WORST YEAR EVER...

Opps Twas a double post.

You know that if you bought it form someone they have temporary fixes. I had this done twice after spending over $400 on Xboxs. I couldn't fix it, same with 1 PS3. Never buy used PS3's because the chance is that they are just on a temp fix. So you're pretty fucking screwed. Look on craigslist for a game console mechanic. Only costs like $30-$50.

Don't know much about PS3's but I recommend Google if you haven't tried that already, good luck.

The sellers PS3 that he sold to you, was probably already YLODed and you just need to contact the seller and get a refund. Thats what I would do anyways. Idk about the colour things though.
