Is my ps2 dying or is it already dead?

[Geo147]

This is bad, very bad, I have had my ps2 since about mid-feb and chipped since march wit a no-solder (CRAP) then a neo 2.2 for a couple of weeks, moved onto a neo4r and was happy enough until I played medal of honor:frontline dvd-rip. It started messing me around while I was playing it, not reading the cd and stuff like that. Now it just stays at the browser/sys.cfg. screen and you can hear the drive making all sorts of noises. I'm lucky if it will boot an original I tried metal gear got to the end of the begining cut scene and it failed to read the cd. On the bright side though it can play the first track of a cdr audio cd, the rest of tracks it is unable to read. Could it b that the arm of the laser is stuck or sticking?
Or is my PS2 pissed at me or is it dying? And wot will I have to do to correct the problem? Ne help gladly appreciated.

P.S: A mate rented medal of honor and played it the next morning his v1 machine is completely dead, it won't even turn on.
