all of a sudden this morning, no games will load on my ps2. i installed a harddrive yesterday but am not sure if that has anything to do with it. we took out the hdd and it still isn't working. when we put in a game (real, back-up, or hdadvance disc) nothing loads and the system browser screen comes up. is this a laser problem? we've been trying to adjust the laser all morning but nothing seems to help. any ideas? yrstruly.
