I've had this same problem before but after some dust blowing and tinkering inside, I managed to get my PS2 running smoothly again. However, after a few months of game play it decided to go balls up again with no amount of dust blowing or tinkering able to rectify things this time.
What happens is that it boots up, then continues to ask me to choose a language and time/date each time I turn it on. The system settings show the year as being 1999. It won't read any discs, and when I eject the CD tray it shoots out fast and jams, making a high pitched grinding noise. The tray retracts once I've turned the console off. It also only displays black and white video output. Hoping that it was a possible dead battery situation I replaced the CMOS cell today but to no avail.
The images below show the boot sequence if its any help:

I've tried googling for the same problem but have yet to find any useful material. If anybody can at least identify a possible source of the problem that would be great!
Thanks
